Insignia™ - 26,800 mAh Portable Charger for Most USB Devices - Black

Cons: This Battery-Bank is long and heavy. But, that's expected based on it's higher capacity. The edges, while not sharp, are barely rounded. Pros: It came fully charged. It's refreshing to see stated on the device and instructions the "actual-delivered" amp capacity at the higher output voltages, rather than just the battery's capacity at their lower "stored" voltage. Extra Info: You'll lose "energy (watts)" as the bank increases voltage from it's batteries to it's output USB port; and again you'll lose energy through the cord and device to be charged before that energy is stored inside the device's battery. At 5 volts delivery .....easily 15% is lost getting out of the bank, and another 15% is lost getting through the cord and into the battery on the end device that you are charging. So, if you're trying to find out how many charges you can get out of this bank (at 5v) by dividing the "stored" 26,800 milli-amp-hours by your device's "stored" mAh, make sure that you reduce the result by 30%. And ... the higher the output voltage the more energy is lost... meaning the faster charging at the higher delivered voltage (9v) gives you less number of charges... using the smaller "C" port on the bank. This is not a knock against this bank, it's just how any battery-bank works, based on today's technology.

Pros: works great. Charges device very well Cons: bulky, heavy, & basically overall HUGE (added pic for comparison) (I will admit, that is MY FAULT for not checking the specs before ordering) I feel like the device takes forever to fully charge. Left it charging over night and woke up and the last blue light was STILL blinking, indicating that it wasnt fully charged yet. (Put it to charge with 2 full blue lights, so it was anywhere between 50% - 75% charge when it put it to finish charging overnight)

I had alot of portable batteries but this is the best one I take it everywhere with me. I decorated mine lol

Worked well and provided multiple charges or tablets and phones before depletion. It's been exactly a year, and now I'm hearing a high pitched frequency sound while it's charging devices. It now also does not immediately light up when charging.

Great charger! You can charge your phone while using it and then charge your iPad Charger lasts for two days and I use mine multiple times a day.

Good battery pack over all. I use it for camping and in case of an emergency. It can charge small devices quite a few times.

Best value, quick charge, lasts long time, charger iphone 14 pro battery ~20 times

Very good charger, just a little heavy in weight but reliable.
