6PCS 9900mAh 18660 3.7V Rechargeable Battery and 2 Bay USB Batteries Charger Suit for 18650 Flashlights, Headlamps, Doorbells, 3.7 Volt Batteries Charger Suite

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

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.

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!

These work great 😀👍

Great little light a bit smaller than the original atomic beam but every bit as bright the flood setting coverage is a bit smaller but the smaller size is great to slip in pants pocket' the charger is clean and compact and also works well and having the extra batteries is a real plus. i was hopeing it came with a sleeve for the 18650 battery but no such luck (I made one out of an old plastic party cup) also no storage case for the extra batteries. Overall a nice little package for the price. I would buy it again if i need another light.

These batteries work great with a long last after charging and they are true to size fitting the product I needed them for with ease. It shows the charging mode green when the mode is complete from red so the modes are easy to read The weight is normal for these batteries and the versatility is great.

the flashlight seems fine, but if you're buying this for those 9900mAh batteries, note that I'm measuring an effective capacity more like 1120mAh. Which might be fine for a flashlight! Just don't expect the relatively huge capacity that the labels imply

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