Customer Ratings & Reviews

Extends portable electronics on the go. Bulkier than other models, but significantly greater battery life. Recharging from vehicle DC shows full when empty, and charging from hotel AC is a slow process due to trickle charging. I will alternate between two units during my next road trip.

Very heavy duty, charges iPad, and lasts a long time.

Love this charger! It charges my devices so fast and holds a charge on itself for a long time! I had one that lasted about a month, but the input receiver slot broke. I think it was just a weird fluke. I exchanged it for a new one and no problems since. Great charger and great price!

This portable battery is for a family & for long road trips. It holds a lot of power for over 12 charges & for a single person it was a bit much. If you have a family I highly recommend you get this or something like it for everyday use or have for a backup.

Bought this to save my phone from imminent power shut off on long trips and occasional no access to a charger. This Charger works great, I can usually get about 8 charges from it from 10% all the way back to 100% before having to recharge the battery charger itself. However it does take a long time to charge the portable battery, several hours. Over all good portable battery charger.

This battery charges my iPhone 6S plus 5 times before I need to charge it again. Only downfall is, it takes around 12-13 hours to charge. Only right that it takes that long since the battery is so large. I recommend it!

I love this powerpak, my Nexus 5 has a less than adequate battery life and Im not yet ready for a new phone, this makes the difference while on the go. It takes a while to charge it fully ~ 6hrs maybe. But it charges my phone and tablet pretty fast. Will recommend

This charging brick is awesome. I can get 7 full iphone / ipad charges on one brick charge. The only drawback is the size and weight. I don't mind it though.

I bought this charger thinking it would only be able to charge my phone once or twice. I was definitely wrong about that. It will charge my IPhone 7 Plus multiple times before this charger even begins to think about losing a little bit of charge.

It's outstanding. I used it heavily on a cross country road trip in a car with no cigarette lighter, and didn't have to charge it once in four days and 2,500 miles.

Recently went on a 2 week trip and this worked overtime charging phones and iPads alike. Never had any issues except when trying to charge it with a smaller power block like one of those that come with a iPhone. When I switched to a usb wall plug it worked fine.

Best powerbank I bought and highest capacity I've found in any store; I have an iPad and iPhone so this makes charging both fairy easy and at the same time, I can use this to charge my iPad from 10% to 100% about 2-3 times and my iPhone 6s Plus about 5-7 times from 10% to 100% or both iPad and iPhone twice at the same time.

It is portable, holds a charge for a long time, and will charge my phone 4 or 5 times before I have to plug it in. I travel often and having this is in my backpack helps me not have to worry about when I will have time to plug my phone in next!

This thing is huge capacity and certainly acceptable in size for the amount of charge it holds. Not too heavy and certainly smaller and lighter than other high capacity batteries that only have a fraction of this things capacity. If you looking for a portable battery that can charge an iPad and 2 power hungry phones and still have charge left for more, this is what you want... and it's less expensive than other big name brands. I've been on a couple cross country trips and it was more than enough to keep several devices topped off at all times.

The reviews on this product supersede its performance as a compact charger...used for my phone..tablet..and so compact..easy to use..easily fits into my purse and readily available at my fingertips when either device is running low on battery.

This is a very powerful charger. It will charge my almost dead iPad at least 3 times. Charges the iPad quickly even while I use it. It is a little heavy but not bad for the number of charges you get out of it.

This is my only and first portable that i had purshased from Best Buy and so far so good. I really like it that it last a long, long, time before i had to charge it. So if you are thinking on purchasing one i do recommend this insignia.

I bought this as an alternative battery replenishing source. I travel regularly and often. When there is no outlet and the battery is low, I boost up with this little bad boy. I am super impressed with the amount of charge this guy holds. I've charged my iPhone a few times with it off the same trip and have yet to run it down. This is a must have if you are in need of stored power, plus the multi USB ports come in very handy if you more than one device you need to charge. I do not leave on a trip without it!!

I love this charger. I carry it with me at all times. It safely charges my ipad, iphone and mp3 player several times without needing to be recharged. I raved about how useful it was and my daughter also purchased one as a result.

I love the capacity on this. I did own two, but one took an insane amount of time to charge, and then failed after a couple weeks of usage. The second one is absolutely fine, but with the failure, and when trying to replace it, being told they no longer carried it in the store, I had to dock a star
