If you have a smartphone, you already know that mobile accessories have become part of everyday life: ultra-fast chargers , power banks, cases, headphones, car mounts… Nowadays, the phone is not just the device, but the entire ecosystem of accessories that surrounds it and makes the difference between using it "plain" or enjoying it to the fullest.
Throughout this guide, you'll find a detailed explanation of all the types of accessories that are currently popular in major online stores: from the most basic products to protect your phone to more advanced options for photography, sports, summer, storage, and battery life. You'll also see what criteria a store uses to rank results, what promotions they typically offer, and some practical tips to help you make the right purchase.
Mobile accessories: functionality, style and online deals
Large specialty stores have transformed their accessory catalogs into veritable showcases of functionality and design . In one place, you can find everything from high-speed chargers and high-capacity power banks to lanyards and decorative accessories to personalize your phone with a unique touch.
These online catalogs typically reorganize completely each time you select a filter or category . When you choose a search option, the page reloads and displays new results tailored to your selections, such as brand, accessory type, price, or relevance. Often, you can also open the product in a new window to easily compare multiple items.
A key point is that these stores' prices are designed for online purchases . They typically indicate that online prices may differ from those found in physical stores in mainland Spain and the Balearic Islands, and that promotions are only valid for products sold directly by the chain itself, excluding marketplaces or third-party sellers.
The ranking of results is not random. They are typically ordered according to several relevance parameters : the match between your search term and the product page, popularity among other users, actual stock availability, the item's relevance to the searched category, and recency (recent releases). All of this influences what appears first when you search for "mobile accessories."
Many of these stores also link to advertising and financing terms and conditions , with very extensive legal texts, explaining that they collaborate with hybrid payment entities such as CaixaBank Payments & Consumer, that money is protected in separate bank accounts, and that transactions are subject to approval by the entity.
Financing and purchase conditions for accessories
One of the advantages of buying accessories online, especially if you place a large order, is the interest-free financing options . Many retailers offer deferred payments over 3, 6, 10, 12, 18, 20, or 24 months with 0% APR and 0% nominal interest rate, provided a minimum amount to be financed is exceeded (for example, €299) and the conditions of their own credit card are met.
To give you an idea, a typical example would be a purchase financed over 24 months for around €654, resulting in 24 installments of €27,25, with a total amount owed equal to the cash price, with no additional costs or interest. This type of financing is based on the French amortization system, where each monthly payment includes a portion of the principal and, where applicable, interest.
These financing campaigns can be general or tied to specific promotions . It's common to see specific promotional periods such as 0% APR financing on certain SSD drives from brands like Sandisk or WD, or on new product launches from leading companies like Dyson, with very clear start and end dates and a warning that they cannot be combined with other offers.
In addition, there are marketing activities such as sweepstakes or promotional spins (for example, the so-called "Crazy Wheel" ) in which only purchases equal to or less than a certain amount can be entered, and only on the same day the order is placed. These are usually managed through the store's own app, where you try your luck once the purchase is validated.
In all cases, the websites link to specific pages where you can find more details about the payment methods for the card associated with the financing, including fees, limits, terms and conditions, and other fine print. It's important to read these carefully before deciding to finance accessories, even if it's interest-free.
Essential accessories: cases, covers and back covers
Among the most sought-after accessories for any smartphone are cases, covers, and back covers . They are the first line of defense against bumps, drops, scratches, and daily wear and tear, and they also allow you to personalize the phone's appearance.
Specialty stores offer cases in a variety of materials and styles : flexible, shock-absorbing silicone; leather (real or synthetic) with an elegant finish; rigid plastic for those who prefer lightweight protection; and even aluminum cases for those seeking extra durability. Within each material, there are plain designs, transparent options, cases with cute drawings, cartoon motifs, or more understated patterns.
For those who can't stand using a phone case, it's normal for the original back cover of the phone to eventually become scratched, faded, or even broken. In that case, it's possible to replace it with a new one, compatible with brands like Samsung, Bravus, or other less common manufacturers. Changing the back cover is a quick and relatively inexpensive way to give your phone a fresh look without adding extra bulk.
Some stores go a step further and offer personalized phone cases , where you can add a photo, logo, phrase, or collage of your choice. It's a very popular way to personalize your smartphone or give an original gift, while also providing good protection thanks to durable materials.
It's also common to find cases and covers from original brands like Apple or Samsung , which fit each model perfectly and usually take better advantage of features like MagSafe, wireless charging, or side buttons. For tighter budgets, there are third-party cases with excellent value for money and made of durable materials, which more than adequately fulfill their protective function.
Screen protectors: glass, bumps and scratches under control
The screen is one of the most delicate parts of a mobile phone, and also one of the most expensive to repair. That's why quality screen protectors have become another essential accessory. Their purpose is to absorb impacts, prevent scratches, and minimize damage from unexpected drops.
There are tempered glass, hydrogel, and other types of screen protectors on the market, but what really matters is that they're adapted to the specific size and model of your phone. Wholesale and retail stores offer screen protectors specifically designed for Samsung, Huawei, Xiaomi, Apple, and many other brands, ensuring a perfect fit over the visible area of the screen, the front camera, and the speaker.
In addition to protecting against impacts, these accessories help prevent the surface from being scratched or chipped by keys, sand, or any hard object that might rub against it in your pocket or bag. Some models include anti-fingerprint treatments to reduce fingerprints and make cleaning easier with a simple wipe.
Major manufacturers, such as Apple and Samsung, typically offer their own official screen protectors , designed to integrate seamlessly with the device's front and maintain optimal touch responsiveness. However, many users opt for compatible third-party alternatives, which offer virtually the same level of protection at a lower price.
Most online stores clearly indicate whether the screen protectors are flat or have curved edges , their hardness level (9H, for example), and whether an installation kit is included. Taking a few minutes to apply it correctly saves you from future problems and extends the life of your original screen.
Headphones for mobile phones: sound, calls and sport
Headphones have gone from being a simple accessory to becoming one of the star accessories for mobile phones . They are essential for listening to music, watching videos, playing games, making video calls, or answering calls without having to hold the phone to your ear.
Wholesale and online store catalogs include everything from classic wired headphones to Bluetooth wireless models , as well as specific options for ruggedized brands and devices like Bravus, Sonim, Militartec, and Gorila. In these cases, the focus is on comfort and durability, designed for professional, industrial, or harsh environments.
For the general public, wireless in-ear headphones and over-ear models with good noise isolation are the most popular. Battery life, sound quality, a built-in microphone for hands-free calling, and connection stability are particularly valued, especially when used on the go.
Within this category, there's also a wide selection of ergonomic sports headphones , with hooks or fastening systems that prevent them from falling out while you run, train, or do any exercise. Many of them are sweat and splash resistant, so they can withstand intense sessions without any problems.
Stores like PhoneHouse, for example, highlight that they have a wide variety of wireless headphones at affordable prices, so you can choose the model that best suits your budget and your usual usage, whether for leisure, work or sports.
External and internal batteries for mobile phones
Mobile phone battery life is a major concern for any user. It's not uncommon to spend many hours away from home, running from place to place, and find that at the end of the day the battery runs out just when you need it most . This is where two key accessories come into play: internal replacement batteries and external batteries or power banks.
Regarding internal batteries, it's important to keep in mind that current Li-ion batteries have a limited lifespan . With each charge cycle, they lose their energy storage capacity and their performance declines: the phone lasts for fewer hours, shuts down sooner, or takes longer to charge. To extend their lifespan, it's recommended to avoid letting them fully discharge regularly.
Wholesalers like Tecnogenia offer batteries for Samsung, Bravus, Sonim, Gorila, Getnord, MTT, Militartec, Beafon and many other brands of phones, so you can replace the original battery with a new one and recover lost autonomy, provided the phone's design allows it.
Meanwhile, external batteries or power banks have become indispensable. Online stores offer power banks with varying capacities, sizes, and power outputs, suitable for everything from an emergency recharge at the end of the day to multiple full charges during a trip. Many of these batteries are designed to be lightweight and easy to carry in a bag or backpack.
Some chains highlight that they have a wide range of external batteries with different designs and prices, so you can choose the one you like best and receive it in a short time, accompanied by occasional offers that further reduce the cost of the accessory.
External storage: microSD cards and USB flash drives
Storage is another critical point, especially if you take a lot of photos, record high-resolution videos, or install demanding games. Luckily, most current Android phones have a microSD card slot , allowing you to easily expand the device's memory.
Wholesalers like Tecnogenia work with well-known brands in the sector, such as Samsung and Kingston , offering microSD cards in 8GB, 16GB, or 32GB capacities, among others, typically Class 10 or higher. This guarantees very fast read and write speeds, ideal for moving files, recording HD video, or loading content without endless waits.
In addition to microSD cards, many online stores include USB flash drives and other external storage devices in their catalogs , designed for backups, transferring data between devices, or freeing up space on your phone. Some models have dual connectors (traditional USB and USB-C or Lightning) that simplify direct transfer between smartphones and computers; if you encounter problems, consult the guide " My PC doesn't detect my phone" for complete solutions.
In the context of cheap mobile accessories, these storage solutions are usually very competitively priced , so expanding the device's memory or creating regular backups doesn't involve a large outlay and avoids the classic "memory full" problem.
Car accessories: hands-free devices and mounts
Safety behind the wheel is paramount, and using your mobile phone while driving without taking the necessary precautions can be extremely dangerous. That's why smartphone accessories designed for cars are among the most sought-after accessories.
Online stores offer hands-free systems that allow you to talk on the phone without taking your hands off the wheel , whether through Bluetooth headsets, dashboard speakers, or integration with your car's audio system. These devices make it easy to answer calls with voice commands or a single touch.
Another common accessory is a phone mount to hold your phone at a comfortable height, usually on the windshield, air vent, or dashboard. This way, you can use your phone as a GPS and follow your route without taking your eyes off the road for too long, keeping the device stable and easily accessible.
Many of these stands are designed to adjust to different screen sizes and may include extra features such as wireless charging , 360-degree rotation, or extendable arms. In mobile phone accessory catalogs, these types of products are often associated with the driving and safety category.
These accessories are ideal for those who spend a good part of the day in the car, whether for work or for regular commutes, and seek to maintain a balance between comfort and safety without giving up the features of their smartphone.
Accessories for sports and active living
If you're very active, go running, or hit the gym, you'll probably need accessories designed for using your phone while exercising . This is where armbands, sports headphones, and other accessories designed for an active lifestyle come in.
Armbands for storing your phone allow you to carry your smartphone securely on your arm without it being a nuisance. They feature a front window that lets you see and use the screen, and breathable materials that prevent irritation. They're perfect for running or exercising without having to carry your phone in your hand.
Combined with ergonomic earbuds that stay in place while you move , you can listen to music, podcasts, or workout instructions while you exercise. Many models include built-in controls for adjusting the volume, changing tracks, or answering calls without touching your phone.
In the budget mobile phone accessories sections, you'll also often find other products designed for active leisure, such as small stands for recording videos while playing sports, or mounting accessories for carrying your phone on a bike or backpack.
This entire set of accessories is designed to allow you to integrate your mobile phone into your sports routine without it becoming a hindrance, keeping it protected and controlled at all times.
Mobile photography accessories: selfies and additional lenses
The mobile phone camera has become the primary photography tool for most users. To get even more out of it, accessory stores offer a wide range of photographic accessories , from classic selfie sticks to advanced lenses.
Selfie sticks allow you to position the camera further from your body for better framing, to include more people, or to capture more of the scenery. Many models come with Bluetooth remote controls that allow you to take photos remotely, without the need for a timer or cables, making it easy to take group photos or self-portraits with ease.
In addition, smartphone lenses have appeared on the market that attach to the phone's camera lens. They are usually easy to mount, using clip or clamp systems, and some sync or connect to the camera via Bluetooth. There are wide-angle, macro, fisheye, and telephoto lenses, allowing you to achieve effects and compositions that the native sensor cannot achieve on its own.
These accessories are designed to improve the quality and apparent resolution of photos, taking advantage of increasingly powerful cameras while adding an extra creative touch. They are ideal for those who enjoy taking photos of travel, food, nature, or social media content.
By combining these accessories with small tripods, LED lights, or remote triggers, you can assemble a very complete photographic kit using only your mobile phone and a few well-chosen accessories , without needing to resort to professional cameras for most everyday situations.
Summer accessories and water resistance
As the weather gets warmer, many accessory stores do a kind of "bikini operation" for your mobile phone , preparing the catalog for summer with products designed for the beach, pool, barbecues and outdoor getaways.
Among the most sought-after are portable wireless speakers , which you can take to the beach, the countryside, or a pool to listen to music with a group. They generally work via Bluetooth, with rechargeable batteries, and some models include water and dust resistance to withstand splashes without any problem.
Another must-have accessory this season is the waterproof or submersible phone case, which protects your phone from water and moisture. With one, you can go into the sea or the pool with your phone securely sealed and take photos or videos of your family and friends splashing and playing.
These cases typically feature watertight seals and transparent materials, allowing you to continue using the touchscreen underwater in shallow water or with wet hands. However, it's always advisable to check the manufacturer's recommended maximum depth and follow their instructions to prevent leaks.
With these types of summer accessories, the goal is to make your phone as ready for summer as you are , reducing the risk of water damage or bumps and allowing you to enjoy music and photography in more demanding environments.
Wholesalers and specialty accessory stores
Behind all this supply are both specialized wholesalers and retail stores. For example, companies like Tecnogenia distribute all kinds of accessories for mobile phones and tablets from different brands and manufacturers, with a clear focus on variety and competitive pricing.
In these professional catalogs, you'll find headphones specifically designed for Bravus, Sonim, Militartec, and Gorila devices ; batteries for Samsung, Getnord, MTT, and Beafon models; screen protectors for a wide range of Android smartphones; and microSD cards from well-known brands. The aim is to cater to the needs of both the general public and more specific niches.
On the other hand, stores like MaxMovil, PhoneHouse, and large electronics chains combine the sale of inexpensive, generic accessories with original products from Apple, Samsung, and other manufacturers. On their websites, they emphasize that they offer official brand accessories at competitive prices, along with third-party cases and covers made with durable materials and a good finish.
Furthermore, platforms like MaxMovil specify that the proper functioning of their online store depends on cookies being enabled in the browser, as these allow them to maintain the user session, the shopping cart, and product filtering preferences within the website.
Whether you're looking for professional accessories or just want to replace your phone case, this ecosystem of wholesalers and online stores makes it easy to find exactly the accessory you need , with different price ranges and quality levels, and almost always with shipments focused on the Peninsula and Balearic Islands in the case of Spain.
Offers, promotions and pricing policy
Websites specializing in mobile phone accessories rely heavily on promotions and special offers to attract users. It's common to find discounts on the base price, themed campaigns (summer, Black Friday, back to school), and bundled accessories that are cheaper than buying them separately.
In the case of large chains, it's usually made clear that promotions and offers are only valid for products sold by the company itself, and not by third parties using its platform as a marketplace. This means that two seemingly identical items may not have the same price or offer if the seller is different.
They also emphasize that online prices may differ from those in physical stores, although orders can often be picked up in-store to save on shipping costs. Furthermore, deliveries are restricted to certain geographical areas, typically the Iberian Peninsula and the Balearic Islands within Spain.
Meanwhile, websites like PhoneHouse encourage users to take advantage of current offers to get accessories at lower prices and receive them in a shorter timeframe. These campaigns are frequently updated and include everything from cases and screen protectors to headphones and external batteries.
Finally, many stores encourage you to browse the entire catalog at your leisure and ask any questions about availability or shipping , whether via chat, phone, or contact form, making it clear that their goal is to advise you and help you choose the most suitable accessory in each case.
With this wide range of accessories—cases, screen protectors, internal and external batteries, microSD cards, headphones, car accessories, sports products, photographic accessories, and water-resistant summer options—it's clear that the world of mobile accessories goes far beyond a simple charger: choosing each piece wisely allows you to extend the life of your smartphone, gain convenience in your daily life, enhance photography and entertainment, and adapt the device to your lifestyle, always taking advantage of the offers, promotions, and payment options offered by major online stores.
