With a capacity of 10400mAh, this power bank can provide four to five full iPhone charges. It pushes a max of 3.1A of power across both USB ports. You should have no problem stashing it in your carry-on luggage or even your coat pocket as it’s just 4.4 x 2.8 x 0.8 inches in size. Rated 4.5 out of 5 stars from over 2,600 Amazon reviewers.
Keep in mind that you’ll need to provide the charging cables. I’d recommend stocking up on these Apple-certified MFi Lightning cables for $6.99 with coupon code GS5VLUIG at checkout.
Check out these deals from the weekend if you need even more portable power.
