18650 Battery Charger 2 Slot, and Tactical Flashlight, Super Bright Waterproof Handheld Flashlights for Outdoor, Emergency, Camping(Use 9900mAh High Capacity Battery)

These work great 😀👍

Nice charger that runs off any USB port. And the batteries seem to hold a charge for impressive amount of run time.

Firstly, the battery has a counter-intuitive +/- install (+ is down on the spring). Secondly, the multiple light levels are in both steady and flashing modes (flashing might be good for some instances, but BAD for epileptic, etc.). Depending in which mode it was turned off, it might require multiple clicks to get the desired mode. This is true for both small and large areas. Also, threading care is required when installing a new battery. Other features are great. It can be very bright; has a great battery; has a great USB charger (with only minor green/red led quirks); it charges quickly; & lastly, this is a great price for 6 included batteries!

This Maxiaeon charger comes with four 18650 batteries. Here's a couple of things to know. The batteries were individually wrapped in plastic. Charging went much better once I removed the plastic. Second point, I plugged into a USB charging port powered by a 2.0 18V battery, the type used on drills and other tools. I first thought the Maxiaeon charger was faulty because the 1st 18650 battery showed charged after about 5 minutes. Switching power supplies, I got charging results that I believe are accurate. So, I am pleased with this purchase. I have four flashlights that shine brightly.

Original battery that came with flashlight didn’t last past three or four recharges. These have beat that already.
