Looking at a range of devices that can charge your electronics, store your files, or even keep up with your needs entirely, each of these maintains a slim form factor that can be carried when you’re on the go. Based on what customers say about these items, each of these devices has something to offer besides a slim design. We also did our best to look for items that play well with different operating systems and electronic devices where applicable.

While we mention cases where items offer different purchasing options, be aware that many also offer different colors, if aesthetics are a concern when choosing a device. If you have EDC items in mind, it might also be worth taking a look at some sleek, minimalist gadgets that can fit in your pocket, because you can never really judge a device by its size alone. If you’re the type who wants to squeeze an extra gadget into your pack, the options below may even save you a little more space.

At 0.7 inches thick, what’s notable about the Amazon’s Choice INIU Compact Power Bank is that it promises to be TSA-compliant and plane-travel-ready. Besides users having access to 45W fast charging that promises to charge a Samsung Galaxy S26 Ultra to 75% in 30 minutes, this 10,000 mAh battery also includes a nylon braided USB-C cord that offers charging capabilities as well as portability options. This power bank also includes a charging stand and a built-in flashlight.

Available in an assortment of colors, INIU touts that the device was designed to be stored in pockets or bags. Compatible with a variety of devices that charge via USB (the charger itself has two USB-C ports and one USB-A port), this charging bank also includes 18-layer SmartProtect features that can help manage things like voltage, current, and heat. Remember that the TSA will likely still expect you to keep this item in your carry-on bag.

We reviewed a battery from INIU as a more powerful compact battery than you might think, but customers on Amazon also give it a 4.5-star rating with over 24,780 reviews. Praising this power bank for its charging speeds and portable size, customers also give points for its reliability. Regardless, some report that the battery itself may not hold a charge as long as one might expect. Still, the multiple color options and small size can make it a fun option to consider.

Given the increasing cost of components these days, some may want to consider the Maxone 500GB Ultra Thin Portable External Hard Drive simply for the price. While we’ve gone with the 500GB model for this list, be aware that 160GB, 320GB, and 1TB sizes are also available with corresponding costs. At just 0.4 inches thick, this drive also features an all-aluminum design as well as compatibility with a wide range of devices and formats.

Offering support for both USB 3.0 and USB 2.0 technologies, Maxone has also included a 19-inch USB 3.0 cable that promises plug and play compatibility. However, this drive still offers read and media speeds of 625 MB/s as well as a data transfer rate of 5 GB/s. While there is broad device support, it’s worth mentioning that the company strongly recommends going for 250GB or more if you plan to use the drive with an Xbox or PlayStation.

This Amazon’s Choice item ranks 4th on the retailer’s list of best-selling external hard drives, and it also holds a 4.4-star rating among customers after more than 59,900 reviews. Although some may wonder if hard drives are still worth buying in 2026, users like this one for its storage options and easy connectivity. Noting that it offers fast speeds, some claim that the device itself can be somewhat fragile. Either way, this one is worth a look for the number of storage options it offers.

If you’re unfamiliar, Life360 focuses on location sharing, offering gadgets that can locate certain devices, pets, or even your family members. Taking the shape of a credit card and intended for a variety of locations, Life360 boasts that its 0.1-inch-thick Life 360 ​​Tile Slim Bluetooth tracker is the company’s thinnest tracker. However, it is not just about the size of the device as the device also comes with its fair share of features and capabilities.

Including support for iOS and Android, this device is intended to track a variety of different objects, including items such as luggage and passports, although users will need to use a companion app to locate objects. However, what’s interesting about Life360 Tile is that it includes a button that allows users to find a phone even if it’s silent. For an added safety measure, there is also an SOS alert that can notify others in the event of an emergency.

For what it’s worth, we found this device to be ideal for making international travel with your phone easier, although customers give this item Amazon’s Choice 4.4 stars with over 8,500 reviews. Users love the Tile Slim for its search and search capabilities while complementing its functionality with wallets and bags. While points are given for the functionality of the device, some complain about the battery life and the fact that it is not replaceable. However, Life360 promises that the device will work for 3 years.

Measuring just 0.55 inches thick, the company claims the Trebleet Ultra Thin 65W USB-C Charger is the thinnest 65W fast charger “yet.” On Amazon, users give this one a 4.4-star rating with over 330 reviews. This wall charger includes both 12W USB-A and 45W USB-C ports. Be aware that an E-Mark USB-C cable is required to achieve 65W charging speeds. This charger also maintains its compact size by being flush to the wall, which Trebleet says can make it suitable for virtually any outlet.

Besides a compact design and modern charging speeds, this Trebleet charger also supports compatibility with a wide range of popular brand devices, including MacBook Pro, iPad Pro, iPhones, Google Chromebooks, iPhones, Nintendo Switch, and more. It also includes intelligent temperature control that reduces power output whenever the device’s temperature reaches 149 degrees Fahrenheit. The company also promises 24-hour customer support.

Looking at what customers have to say about this Amazon’s Choice item, several compliment the charger’s slim profile while giving it high marks for portability. While users like the device’s charging speeds, many also point out that the device can have heat issues, especially when using 65W charging. Since this one requires a special cable to reach 65W speeds, users may also want to consider whether they are using the right USB-C charger for their phone.

Last on our list is the Amazon Samsers Foldable Bluetooth Keyboard with Touchpad which has a thickness of 0.71 inches when folded into itself. Users may want to check specific software compatibility, but this wireless keyboard touts its ability to work with a variety of devices, including iOS, Android, and Windows. As an added benefit, this device also includes a free adjustable phone backrest, and there are a few extra benefits built into the hardware as well.

Boasting 120 days of standby time, Samsers also promises up to 48 hours of use on a single 2-hour charge via USB-C (cable included). The device itself packs a full-size keyboard with 0.63-inch keys with touch-sensitive keystrokes, as well as media controls and additional feature options. For connections, users should be aware that the Amazon page offers single-device or three-device connectivity options, depending on the model, but both rely on Bluetooth to maintain wireless connections.

On Amazon, users love this device for its compact size (one user saying it’s ideal for international travel) and portability, which likely contributes to its 4.3-star rating with over 3,470 reviews. Praising it for its battery life and value, some users found it too small for their hands, while others also report connectivity issues. Of course, those interested in a portable keyboard may also want to consider these foldable keyboards, which are perfect for traveling.

For this list, our main goal was to look at devices with a slim design. However, this is not the only thing we took into account, as other factors such as user reviews also played an important role. Items should generally have a 4-star rating or better, based on hundreds or even thousands of reviews, but we’ll also look at what users have to say across the web, if anything. We also award bonus points to items that have received an Amazon’s Choice distinction or other special consideration.
