Customer Ratings & Reviews

I love this small charger because it's size makes it convenient for me to put in one of my pockets when I go for my daily walk at lunchtime if my phone happens not to be charged. And it takes up very little space in my purse! It is a great charger and very inexpensive!

We bought these chargers on sale. Used them to provide phone charging at music festivals. It’s a little larger than I anticipated, but still fits easily into pockets. Works great and provides 1-2 charges. Recharged quickly and holds its own charge well.

Solid little battery pack. Good for recharging small to medium (iPhone 6) phones twice, larger phones (Note series) once. Recharges quickly. Small size is great to shove in a pocket or your purse and go. Wish it charged a little faster and had a little more juice, but the this is reflected in the low price. Would recommend.

Works great. Charges phone fairly fast, and I can use phone while charging. I bring it with me on long hikes as tracker on my phone uses up battery. It is nice and compact to fit in my small hip pack as well is in my purse.

Been using it several times a week for quite a while. Very good quality, unbelievably easy to use. Definitely worth what I paid for it! Keeps and holds charge for pretty long time, great for recharging devices when away from the house!

Good charge capacity, very compact, great price, nice battery level/charge status indicator. Very handy to have available. I keep some of these in my hiking pack and the kitchen desk to take with me on the run. I get two good phone charges from one battery.

We bought two of these to use at Disney World. They were good for about 2 charges, (1 full charge) with a phone battery of 30% left. They did the job, and I would recommend them. Just don't forget your device charger. It comes with a short cord to charge itself. Small and easy to carry around in your pocket.

We have been very happy with these little batteries. They charge easily in the car without overheating the charger the way a larger battery would. They are inexpensive enough to leave charging at work. They seem unable to charge some micro-USB devices, such as our headlamps, but work well for iPhones.

I have tested it twice and it has been able to charge my phone with battery capacity of 4000 from 0 to 100%. Generally speaking, slow charging keeps battery health good as per my understanding so overall satisfied with product.

I took this on vacation and it definitely charged my phone fast! It only went up to 80% and stopped charging there, I’m not sure why. But it wasn’t a problem at all because it helped my phone last all day!!

...this mini power bank is perfect for a purse or even your pant pocket. It holds plenty of juice and great back up power. Have purchased before and very pleased with it's service, why I purchased again as gifts. Insignia has yet to disappoint.

Grandson need when traveling out. Phone was always dead and needed to stay in touch. Now he don’t have a excuse when I text or call. And it’s small enough for him to put in bag or pocket. It’s made very well and strong. No more missed calls.

This charger is one of the few that can get me multiple charges on devices when they are almost empty. This seems to charge my phone faster than some of the larger power banks too. Very satisfied with this product especially at this price.

Great little device. Took on vacation to Florida. Was able to recharge iPhone while in parks. Perfectly sized to fit in pocket or a purse. Able to use phone while on charger as well. Great tool especially for the price.

The was a great choice for me. I forgot my portable batter on this day. I went into Best Buy looking for a small portable battery and fob d this one. It’s good fit. It works very will

Bought this Powerbank on Best Buy's early Black-Friday deals and I must say it does its job very well!! With family over for the Thanksgiving holiday was able to use this Powerbank when the battery on my phone was running low from all the picture taking and short video taking. A great deal for a good "go-to" type powerbank!! If you need more juice then step up to a higher one, BUT this is as good as it gets if you're only needing to charge one device and don't need a higher amperage one!! Am considering a one or two more for a niece and nephew of mine since the Black-Friday pricing is still going on!! Again overall, a great mighty might Powerbank!!

Great portable charger. Got this item on sale for next to nothing. Loved it so much I bought two. Charges fast and is able to power up devices with some left in reserve.

I test all power banks I buy with a USB tester and dummy load to check performance. The specs on this one are legitimate! It provided roughly 5V up to 2A and fully charged to discharged measured 3200mAh. This is actually good - power banks are advertised based on the battery voltage of 3.7V, not the 5V it actually supplies. They are also not 100% efficient, there are losses when the voltage is boosted to 5V USB. Power banks are typically 85-90% efficient. 3200mAh @ 5V is 4324mAh @ 3.7V which is about 87% efficient - perfectly acceptable at this price point.

I got this to charge my iPhone in a pinch and it has been great! I can typically get 1 full charge of iPhone 6S with this and a 1/2 charge before having to recharge the power bank. Super size (fits in any pocket!!)

Nice size works as directed. I think I does well on charge of small device if your looking for greater device charge u want to look for a 20 or 30 mah. Again great for normal uses
