My first choice for portable power banks is Anker

Sure they're are more powerful charging power banks but this one is sleek and gets the job done and lasts plenty long

Love my new power bank

Works great, about the size of an average smartphone, I can place both my phone and power bank in the sleeve provided.

Excellent power bank for a cellphone

Good power bank and fair price $20

I first had a cheap little power bank from dollar general that would charge for 30 seconds then stop

The best battery charging bank you will ever buy

Probably the best portable power bank

I think it's a phenomenal power bank without breaking the bank lol.

I highly recommend this power bank if you are looking for dependable backup power that is portable and affordable.

Great power bank!

I usually prefer dual USB battery bank and gave this a shot for the price but definitely not worth it.

Priced low enough to let the kids use them for their school tablets (& not worry about them dropping my other more expensive portable chargers) as well as to buy more for backup use

I've purchased several for myself as well as for gifts.
