Portable Charger Capacity 2200Mah Lithium

Good little HD. Great capacity and portable.

I love the compact size of the charger, and it seemed to charge my lithium batteries quicker than my last charger.

These lithium batteries are very light and last a long time. Charger works well too.

I have used Energizer Ultimate Lithium batteries for many years and have never had a problem with leakage. The capacity of the batteries doesn't diminish even after years of storage. These Energizer batteries are absolutely dependable especially for camera flashes and flashlights. I highly recommend these lithium batteries. I have used other batteries but these are the best.

I purchased this, not for analyzing rechargeable batteries, but for measuring capacity of several different brands of lithium AA batteries. There is a common knockoff of this product that didn't actually work for my use case, but I did use it for charging batteries, and I can say that the user interface of the Powerex is much more intuitive and easier to use. As far as customer service, I emailed Powerex to find out if this would do what I was trying to do, and a representative called me and let me know that while it is not an officially supported use, it would work, which proved to be true. I would definitely buy more products from them after having that experience.

For disposable batteries, these are the best! They really do have 9x the capacity of standard batteries - Consumer Reports tested them. They ARE lithium batteries so they weigh less. I've never had any fire or overheating problems but I am aware that lithium batteries can have these problems. They have a long shelf life as well. I primarily use rechargeable batteries but I keep these in my camera bag as a backup. The price from B&H is competitive.

I have many many of these and they work well in the Olight I use them. Like all lithium cells, they eventually lose their capacity as the number of charge cycles increases, but it takes a while for this to happen and a replacement is inexpensive. The USB charging feature works well -- I use this almost as often as I charge these in a stand alone charger.

Very portable with decent storage capacity

I use the watson cr123a rechargeable lithium for my personal portable air cleaner. I get around 80 hours of use before I have too recharge the batteries. And as usual B & H is superb in delivery fast. I highly recommend the Watson cr123a rechargeable lithium battery.

In less than three and a half hours, a Remote Audio Hi-Q Portable Lithium-Ion Battery (98 Watt-Hours, 14.4V) is fully charged,really !!!
