The Best Portable Chargers and Powerbanks for your Smartphones in 2021

There’s really nothing worse than running out of battery on your smartphone, especially when you need it the most. When your phone dies, you realize how important it actually is! Suddenly, you can’t call or text people, and it’s significantly harder to look things up or get directions. If you have a phone with a failing battery, or just have a lot of programs going on in the background, a low battery warning might just be a fact of life. If that’s you or a loved one, there’s a solution to your problem — a portable charger commonly referred to as a power bank.


You can charge your phone while out and about, and you won’t have to worry about not having a dead battery when there’s an emergency. Even if your smartphone is good on battery life, having a charger stored away can help if you forgot to charge your device or if you’re traveling. It’s a great companion to have on a flight when you’re whiling away time watching your favorite shows or even a road trip when you’re constantly using GPS.

    Slim and light

    This slim power bank from Anker is a part of its PowerCore lineup of portable chargers. It supports fast charging and is quite slim which makes it a good fit for traveling. You can charge it via a micro-USB port or Type-C port, and it has a USB-A for output.

    Charge Everything. I Mean Everything.

    Want to be able to charge everything from one device? Omnicharge's power bank will be what you want to grab. Charge your phone, laptop, and everything in between with this big power bank.

    In-built cables

    This is a slim powerbank which means it's easy to carry around in your pocket or while you're traveling. It comes with in-built cables -- both USB-C and lightning that just slot into the sides when not in use. It's a really convenient solution.

    Small, Round, and Cheap

    While this battery pack isn't as strong as other power banks on this list, the low price and compact nature of Anker's PowerCore make it an easy choice. You can easily slide this into the side pockets of your pants along with your phone and it will give you a quick top-up, enough until you find a socket.

    Big Battery for Multiple Charges

    This portable charger from Baseus is one of the few on the market with 30,000 mAh of power, meaning it can charge more before needing a charge itself. However, this is not an air-travel-friendly charger, so this battery pack is for domestic use only.

    Keeps Going and Going and...

    Exclusively at Best Buy, you can pick up a portable charger from Energizer, the well-known battery brand. You know you'll get a quality charge with one of these. There are a variety of different charge amounts, but I'd recommend the 20,000mAh one.


    Despite having a large capacity of 10,000mAh, this power bank or portable charger from AmazonBasics is quite compact and can easily fit into a small compartment in your backpack, or even your pockets. Very handy while you're on the move.

    Charge wirelessly

    Apart from the huge capacity of over 30,000mAh, this power bank has a unique feature - wireless charging. It has a pad on the top surface where you can rest your compatible devices and they can be charged wirelessly. It even displays battery levels.

    Best for fast charging

    This power bank supports Quick Charge 3.0 as well as USB-PD up to 20W which makes it a great option to charge most of the new Android phones as well as iPhone devices since they now support 20W charging. It can output to 3 devices at once.

    Plug and play!

    Instead of carrying a bulky powerbank with you, this small gadget plugs directly into the lightning port of your iPhone so it's easily pocketable. It's easy to carry, doesn't need any cables, and it's got 4500mAh capacity so it can give you a full charge.

    MagSafe compatible

    This is an all-in-one powerbank with a 5,000mAh capacity. You can use it to charge via a cable as you would normally do, but it's also got wireless charging and MagSafe support if you have the iPhone 12 or 13 series so you can just snap it on the back!

    Great for outdoors

    If you want a powerbank with a high capacity to charge multiple devices, this is a good option. It even has a solar panel for charging so if you go outdoors a lot, this can be a great companion. Great for camping and hiking. You can charge up to 3 devices at once.

With so many battery packs on the market, you can be sure these will stand up to the test. My personal recommendation is the Anker PowerCore 10,000mAh, which is my go-to for day-to-day use, especially with my aging phone’s slowly failing battery. From there, it all depends on your preferences. If you travel a lot, Omnicharge’s power bank will be great not only for your phone but for your laptop as well. I have this power bank and trust me, I use it to charge pretty much everything as it’s hard to access a lot of my outlets. It’s great!

If you just need something you can carry with you everywhere because you forgot to charge your phone or the battery can’t last the whole day, the smaller Anker Powercore is super easy to pack anywhere, is cheap, and can top off your phone when you need it the most. You can’t really beat that combination.

Once you have picked up a power bank, be sure to look at some great USB PD fast chargers and power adapters too.
