Customer Ratings & Reviews

I returned it. Each time I charged the battery it would take over 24 hours.

I started looking for a portable charger when I realized I was going to making a trip via van to New Mexico. I live in Oklahoma and the trip was gonna be 12-14 hours depending on stops that we made(a group of us from my college). I was worried about having phone battery that would keep up and keep me entertained for the trip when I couldn't sleep or taking funny pictures on the van and blasting music. This battery was and still is awesome. The only down side is how long it can take to charge fully if you're pressed for time but charging it over night seems to work well. There are four squares that light up to let you know how much battery power you have used. It works well and can charge 3 things by USB at once. I love it and keep it on my person ALL the time.

I have traveled to Nevada and went on a Business trip to San Diego. This charger was able to charge two devices at once and multiple time before having to recharging it. It is a bit heavy, but worth it. I bought it for traveling and for emergencies. It's always good to have a back up. I have charged 3 devices at once before as well. I would recommend this product. Devices I have charged are cell phones and my tablet.

Charges quickly, only down side is my cell phone does nor stay charged as long as it does when I use the wall charger.

Playing Pokemon go drains my iPhone's battery life quickly so this is perfect for those days when I'm out on the town catching them all.

The device holds 20,800mAh which is much more than the average battery pack and it is not BIg at all. This is must have for anyone who travels and needs power. I wish i had this when I went to Disneyland recently as my GoPro died mid day and having this battery would have solved that battery issue. Speaking of my GoPro, this device also charged my GoPro3 while shooting a timelapse. I hooked my GoPro to it and it lasted for almost 2 days! Anyway it's not just for GoPros it will charge all of your devices and it is AMAZING!

I bought this product because i play pokemon go and i charged 3 smart phones one jbl BT speaker and my gopro in one charge and it still last me for the next day i use it more to play pokemon go and i stream from my phone to twitch it's an amazing product now im a life saver for my family and friends Lol i love it only 39.99 100% recommended

My phone used to hold a great charge. Now I'm lucky for half a day charge. This battery helped keep my phone on for 4 days and nights while I couldn't charge my phone. Unfortunately it and my phone died on the last day but only like two hours before leaving vacation. Definitely worth the purchase. It would have lasted me but I also charged my girlfriend's phone as well a couple times.

A little large but does an excellent job. Will charge phone fully at least 4 times.

Easy to go. Just a little heavy... Very large capacity. Good device.

This by far is the best portable battery pack on the market!!!! I went for a 6 hour car ride to northern MN charged my phone and headphones the whole way, I can't leave home without this. The only downside is recharging this takes a whole day to get it back to fully charged. I am purchasing another one for myself because its just that awesome!

I love the 20,800 mAh. It can charge my phone 12 times from 0% to full. This has been a wonderful help for those times when a conventional charger is unavailable. As long as you read the questions and answers before buying and realize it's not for laptops, it will suit you perfectly. I have recommended this to everyone I know.

I was looking for a device that would charge I-pads and other devices when power is not available.

Purchased two chargers for my daughters before leaving for an extended trip which would offer limited opportunities to recharge their phones. The chargers worked very well and also allowed their friends some opportunity to recharge their phones. The units were a little heavy but worth it for the peace of mind.

This battery is great for road trips and charging your phone when you need it most. This battery does take a while to charge, but when it is charged, it lasts a very long time. This charger only offers a slow charge if your phone has a fast charging option, but it worked great for me at the time.

Super fast charger. Only negative is that it is a little heavy to carry around.

I used this for the first time on a annual road trip with a couple friends and it charged my iPad, iPhone, and DSLR cameras the whole 8 hour way there. Same for the way back. Takes a very very long time to charge, but if you leave it overnight it's always enough for the day + more.

So I just got this battery pack and it's so awesome!! But when I died and I plugged it in to recharge after a few hours it only had 1 light lite out of 4 lights. I even plugged it into my computer over night and woke up with the same results!! I'm hope I didn't get a "lemon" so please help me out!!

I could get as much as 4 full charge on my phone with this and I also like the charge indicator which lets me know how much is left and gives me ample time to plug it back to an outlet.

This was a great tool for taking on vacation. We were able to charge phones and cameras at the same time and never ran out of power during an entire trip.
