8 high-capacity power banks for the traveling techie


Given today’s power-hungry phones and tablets, any power pack under 20,000mAh shouldn’t be considered high-capacity. While the majority of these beefier backup batteries aren’t suited for storing in your pocket, they’re still compact enough to toss in a backpack, suitcase, or laptop bag for a quick charge when you need it. Check out these power banks that provide enough battery to keep up with the most demanding tech-lover.

A note on air travel: What you need to know

While traveling in the U.S., the Federal Aviation Administration allows you to carry a device (like a power bank) with up to a 100 Wh capacity. You are also able to carry a limit of two spare batteries between 101 Wh and 160 Wh with prior approval from your airline. All lithium batteries must be in your carry-on bag and can’t be stowed with checked luggage.

Most power banks list their capacity in mAh (milliamp-hours) and not Wh (watt-hours). Let’s do some conversion using a 3.7-volt average. You can calculate from Wh to mAh using this formula:

(mAh)/1000 x (V) = (Wh)

After some rounding off, that means you can bring a 26,800 mAh power bank on your flight. With approval, you can bring up to two 43,240 mAh (again, some rounding is used) along as well. Just be sure not to put them in your checked luggage!

Other countries may have different regulations, so you should check before you travel outside the U.S.

Having a portable power bank with you is the best way to keep all of your devices charged wherever you go, and for the money, Anker’s reliable 26800mAh charger is your best option, with USB-C PD for fast charging everything that’s compatible.
