Insignia™ - 15,000 mAh Portable Charger for Most USB-Enabled Devices - Black

Just bought this item few weeks back and used it few times. Seems works ok. Took 5-6 hours to full charge. Little heavy and big in size. It charge the mobile in average rate. I never charged any other devices yet. I should add review comments after using it some more tine.

Awesome product, you may charge your cell up to 6 times

I bought this for a festival and I wasn’t sure how it would hold up all day out in the heat. This is the BEST portable battery pack ever! I was out all day 13hrs and my phone never died thanks to this! By the time I made it back to my BnB, I still had 2 led indicators left on the pack! The box said it would charge your phone 6xs and it’s no joke. There’s no power button on it which is nice so you don’t accidentally turn it on in your page. It automatically turns on when you plug your cord into your phone and it’s nice to charge 2 devices at once. I highly recommend this battery and it’s affordable! Nothing like affordable quality!

I Like How You Can Take It Anywhere And Have Charge!!!!!!!

unit is bulging due to defective batteries inside it. specs say narrowest should be 0.8 inch - it is now a bit over 1 inch. It is still within stated warranty period. Guess I'll be finding out how good the warranty actually is.

I purchased this (primarily) for my wife to use while she's out-and-about with our two young children, to make sure that she always has enough battery life on her phone (and/or our eldest's tablet) to be able to communicate and to entertain the kids. We first used it to maintain the charge on our smartphones on a much-needed day-long date, as we were looking up shops all over the Seattle-metro area, but also needed to keep our phones charged in case our child care needed to get ahold of us. Over the course of the day, with charging our phones on-and-off, we barely used half of the capacity of this portable charger. Our next test for this will be a long day of house-hunting!

I have a RAV Power power bank I've used for years now. Nothing wrong with it but having extra power, and more storage of it, is a plus. I've charged it up when I received it, mere days after ordering!, and I haven't exhausted it yet. I'd say it charges maybe a little faster than any I've used before (that is, relative to the amount of storage in the device). It's a slick design. It charges two devices at once though haven't tried that too much as yet. Both charging ports are USB-A so if you're using a USB-C cable you may be out of luck. This device may slowly become obsolete but I think there's plenty of time before everything goes USB-C. A little thing but one I greatly appreciate the the battery indicator. The LEDs are recessed where one has to look at it face on to read it. The great part of that is that with this design the LEDs will not light up a dark room when being used or charging. When being used, blue LEDs will not distract you out of the corner of the eye. As someone sensitive to needless light I truly like this design. And, as stated, I've yet to use my first charge of the power bank completely yet. Nice Insignia product so far.

Best portable charger I've purchased to date. It charges fast. I love the convenience of having 2 ports.
