I get three plus charges for my IPhone. Fits in my coat pocket and works great

My iPhone and iPad don’t run out of juice any more. It’s a little heavier than I’d like but it does the job.

Holds a charge a long time, and love the size and portability.

Absolutely love my Tzumi- Pocket Juice 12,000 portable charger!! The charging time is FAST and it allows me to recharge my phone a few times a day!! Sometimes I’m charging 2 phones at once and I’m still left with power to charge more!! Best portable charger I’ve ever bought!!

I originally bought this for my fiance but she says it is too big to keep in her purse. So her loss is my gain. I have used it a few times when I'm on the go and my phone battery is getting low. I can connect it to my phone and it charges my phone pretty quickly.

Has good battery life and is fast to charge any device

I purchased this charger prior to an overnight backpacking trip with my teenage son. I wanted to be sure we could both charge our phones and my Apple Watch once we arrived at camp. Not only were we both able to charge, but I still had 85% charge left.

Everything should be moving to USB-C at this point. Too bad this sticks with micro usb and lightning. However, if that's already what you have, you can't go wrong here. High-quality, well built. Should last you a while.

This was great to charge a few phones while in Disney World.. it was lifesaver to keep the phones charged so we had cameras on the phones readily available for pictures of grandkids!!!

Recharges at a descent rate. Needs a longer cord .

A great backup when you're not close to an outlet. My phone's getting older and this is a great alterative to getting a new battery. The LED power indicator is nice to have.

This charger was able to keep five our phones charges throughout the day on a snowboarding trip. The cold drains your phone battery, so this was very handy to get the phones recharged for lots of videos and pictures!

My son just landed a job in New York City and since he travels via taxi subway lyft etc this was the perfect gift for him. Now he will be able to charge his phone or any other device if need be. Thank you Best Buy he loves it.

Because it costs less than some power banks that have half the mAh, I thought it must be made more cheap. I was surprised that it’s actually well made and can charge my phone rather fast multiple times. I use it for Pokémon

This charger is great for on the go charging. It's a bit bigger than you're other chargers but it makes up for that for how many charges you get off of it. It also supports quick charge which is a huge bonus!

I love this extra batttery, I can charge my phone/iPad/etc... on the go. I never worry how much charge I have because it holds so much power I can charge things multiple times.

Love this battery pack. I have use others that depleted fast & didn't fully charge my phone. I can fully charge my phone numerous times before recharging the battery pack.

I bought this at a great price while it was on sale thankfully I didn’t pay full price this portal charger stopped working after a few months

This portable charger worked well for my needs. I purchased it because it had the 12V capacity which is what I needed for the item I needed to power remotely. Worked like a charm.

Great back up charger to have on the go. Will charge a iPhone plus 6 or 7 times fully. Perfect when you’re out all day and can’t leave your phone plugged in the wall for long.
