Customer Ratings & Reviews

I really enjoy this item. It's come so handy while traveling.

Just picked up as it was on sale. Seems to work as advertised

Portable Charger is really good for my Phone perfect for work

It is a bit too big and heavy. I was able to find batteries that were smaller and lighter with nearly the same capacity and better quick charge capabilities. Overall not bad, just not what I was looking for.

I recently used the Tzumi on a camping trip. I charged my iPhone and iPad several times during the 3 day trip. The battery pack worked well and I still had power when I got home so I used it to charge my Apple pencil.

I was thinking of purchasing a portable charger. What impressed me was the amount of charges you get from this charger before you have to recharge it. Great price also motivated me to purchase it. Also it is very compact.

Bought this a week ago with good price, however the charge as others mentioned was taking long. With 2A fast charger, it took almost 36 hours to complete 100% charge for mine. Comparing with my 5200mAh, it can charge about 2.2 times and super heavy.

This charger is an excellent addition to anyone's collection.

But they work awesomely! I had some 12000mah charge packs that failed (would not hold a charge). I got 3 of these to get the the additional Best Buy 25% off accessories, so paid $15 each! And except for the expected bulk, they've been GREAT!

Excellent unit, compact, fairly light weight and powerful.

Works exactly how and when it was needed! Thanks Best Buy!

Reliable charger nice size bought for emergency situations

Bought this for long car rides (6-7 hours). Usually, will last two of these trips with constant charging. Love the fact that I can charge two different devices at the same time. It does take a long time to charge back up.

I didn't really like the fact that it doesn't charge with the original charger I have to use the ue BOOM charger and I had to get a replacement because it wouldn't hold charge anymore after 2 weeks

This product is a Christmas gift so can't give a good review. But good price

Awesome would recommend to any one who is a tech head

this battery pack is amazing, it charges my phone quickly. and i can get multiple charges out of it. also it holds the charge very well. the only reason i'm giving it a 4 star its because it only has 2 ports for charging.

Initially purchased because I had a power outage and no landline. It worked beautifully. Now I will take it with me when I go on cruises. Usually end up on Caribbean beaches and this will help keep my battery life charged. So compact and light.

This works great I have charged my iPhone with it about 6 times without charging it out of the box it did take about 18 hours to charge completely dead but all together best little battery I have ever had!!

Love it love it, would buy again and would recommend
