My wife goes on long bike trips over the week this has to be one of the beast chargers out. It's compact and has a great charge life on it. it last 2 to 3 days for charging her phone and other peoples phones. The price on this is great we found another one at another store it was around the same price bigger but didn't have the charge that this one has.

This battery bank works very well with my phone. It fully charges my pixel 6 pro from dead almost 4 times. I also use it with my quest 3 and I dont have to worry about how long i have left to play. Over all no complaints and would buy again.

I use this on the regular and it works so well. Charges my phone multiple times after only charging it once. It's pretty lightweight for the power that it has and the cord that it comes with is just so convenient to keep in the little bag

Remi, the store manager is exceptional. Treats the consumers with a bright smile & takes pride assisting our needs.
Product: I gave my best Anker away, then bought another & noticed the charger was acting funny so i upgraded to this one as it's like the 1st one i gave away. I'm such a giver. It drives me crazy in my old age.. Ha!

Very good portable charger, with the size of this battery back you could charge you phone from 0-100% at least 2x depending on your phones battery size. Works very well for me and kept my phone charged over a few days without needing to plug the pack in itself.

I use this thing for everything. Charge my phone, airpods, my vape, my gopro batteries, my helmet headset.. I could go on for days. I charged it the day I got it nearly two weeks ago and I havent had to recharge it yet and I use it every day. Worth every penny.

While a little large this charger is exactly what i needed. It carries multiple charges and is basically the same size as a phone but is heavier. It charges up your devices very quickly as well. If i had one criticism it would be that it takes a little long to charge itself. Otherwise it is perfect.

Took this abroad to use in Europe when chargers were hard to find and it worked great - charged me and my friends phone to full twice before having to charge it. It does take a full 8 hours to charge so probably do that while sleeping.
