Most Helpful Review
"Pros: Charges fast and holds a TON of juice. I think we can probably charge our phones four or more times out of one charge. Not sure how it holds up for bigger electronics, but great for cellphones. Also feels really solid and well-made.Cons: A bit heavier/bulkier than we imagined. Not a dealbreaker, but definitely not the most portable. And it takes a really long time to fully charge — like overnight."

We bought this 2 pack a little over a year ago, and primarily use it for travel. The airlines here in Canada aren't bothered with Power banks this size, so its perfect, and although you can commonly get away with units up to 27,000 mAh, not all airlines are the same, so this is the safe bet.Anker seems to produce great products, and these haven't let us down.It's so nice to not have to find a wall plug and wait for your device to recharge. We simply plug our devices into the battery, stuff everything back in out pack, and go find the closest coffee shop and quiet corner.Highly recommend.tony devlin
