The 5 Best Portable Chargers and Power Banks, According to Our Tech Expert

Smartphones keep getting bigger, but smartphone battery life isn’t improving at the same rate. Many people charge their phones in their car, but what about public transit commuters or those on the go? A portable charger can make the difference between staying in touch or being caught in an uncomfortable situation—and the best portable chargers aren’t just useful, but reliable, too.

We’ve rounded up the best power banks and portable chargers to help you charge your phone as quickly and conveniently as possible. Whether you’re on a walk and need some juice or are stuck in a power outage, you can trust these products to see you through safely.

What to look for in a portable charger

Size and weight are going to be a primary concern when buying a power bank. As a rule, the more capacity a portable charger has, the bulkier it’ll be. The key is to find the product that fits your needs without having excess capacity. For example, if you just need to charge your phone once in a pinch, a small one will do. On the other hand, if you want to charge your entire family’s phones, or the same phone over multiple charges, you’ll need something bigger.

Battery capacity ties into the size and weight of a power bank. Find out what size the battery in your phone is and use it to estimate how many charges you’ll get out of a power bank. Many chargers state on the packaging how many hours of power they provide for various activities. You’ll also want to check how much wattage it outputs if you’re looking to charge multiple devices.

Finally, check the connectivity of the portage charger. It won’t be anything more than a paperweight if you can’t connect the device you want to charge to it, and different devices use different charging ports. Some power banks offer multiple methods to both charge them and power other devices. The most versatile portable chargers include an AC outlet, which will let you use a device’s normal AC adapter to charge it, but these tend to be bulkier.

Best overall portable charger

Mophie Powerstation XXL

The Mophie Powerstation XXL is on the larger side, but its 20,000 mAh battery will charge most phones at least four times over while being only a little larger than a smartphone itself. After all, your phone battery life doesn’t last forever, and you may need a quick charge here and there. In addition, the premium fabric finish is soft to the touch, preventing the charger from scratching your phone. You can even charge multiple devices simultaneously with two USB-A ports and one USB-C port. For a reliable everyday power bank, you can’t ask for much more.

• Fabric finish protects other devices
• Great capacity for its size

Best small portable charger

Anker Astro E1

There are smaller power banks than the Anker Astro E1, but most of them don’t hold enough of a charge to be worth carrying. At roughly the size of a small candy bar and 4.4 ounces, it’s easy to carry in a pocket or a purse without weighing you down. Its 6,700 mAh battery is enough to charge a phone a few times, but powering larger devices like tablets and laptops is out of reach for it. Its biggest drawback is that you have to charge it with a Micro USB port instead of the newer USB-C. Ever wondered what your iPhone’s lower power mode actually does?

Pros

What we like about the Anker Astro E1:

• Small and lightweight
• Rounded edges make it comfortable to carry in a pocket
• Affordable price
• Impressive charging capabilities for its size

Cons

What to consider about the Anker Astro E1:

• Charges via Micro USB, which means you have to keep track of another cord
• Won’t fully recharge a larger device

Best high-capacity portable charger

Anker 521 Portable Power Station

At eight pounds, the Anker 521 Portable Power Station isn’t going to be your everyday power bank. However, it’s one of the best portable chargers to have for camping or emergencies. It has a capacity of 256,000 mAh and can output up to 200 watts at a time through two AC outlets, a car outlet, two USB-A ports, and a single USB-C port. It can also be charged up using several methods, including USB-C, DC, through a car, or AC.

It’s impressive that this much power can fit in a package that’s around the size of a lunchbox. And if you find yourself needing to charge your laptop to make its battery last longer, you can use this power station for that, too.

Pros

What we like about the Anker 521 Portable Power Station:

• Massive charging capacity
• Six charging outlets
• Multiple ways to charge the internal battery
• Excellent to have on-hand for emergencies

Cons

What to consider about the Anker 521 Portable Power Station:

• Too bulky to use as an everyday charger. If you’re looking for a smaller charging option, Anker’s magnetic iPhone charger simply snaps on to the back of any iPhone for an extra power boost.
