This product is a pack of two (2) 18650 Lithium-Ion batteries, each with a built-in charger. This is a novel design since they need no external charger other than a common USB-C adapter. A USB-C port is built into the side of each battery. Two indicator lights are on top on the battery that presumably indicate the state of charge, although no instructions were included with the batteries. When the battery is fully charged, the indicator lights are green while charging. A short USB-C Y-cable is included to allow both batteries to be charged by a single USB power supply. No USB power supply is included but any common USB power supply can be used. Since there are no instructions, the minimum current rating of the power supply is not known but a 1000 ma (or larger) USB power supply works fine according to my tests. My batteries arrived fully charged, which was surprising because rechargeable batteries are typically only about 70% charged upon purchase. As stated in the online advertisement and as shown in the photo that I have included with this review, these batteries are about 1/4" longer than most 18650 batteries. This could prevent them from being used in some devices. Indeed, they would not fit in my 18650 charger, as they were just about 1/16 of an inch too long. However, the batteries fit just fine in my LED flashlight. As long as you take the additional length into consideration, these batteries should perform very well in 18650 applications.

18650 Li-Ion batteries are the workhorses of the rechargeable industry. They're used in portable power banks, , Laptop removeable powerpacks, even EV batteries. I make my own power banks as well as custom size power packs. (see pictures) The TEMIBATT 3.7V 2600mAh USB Rechargeable Lithium lon Batteries. are typical weight (49 gr) and proper size for 18650 batteries and charge up to 4.2V exactly as they should. I put them into one of my battery powerr banks and they work well. My only complaint is that their capacity, 2600mAh is a little lower than the 3000-3500 mAh of most of my other18650 batteries.

The built-in USB-C port makes it easy to charge these 3.7v batteries on the go and it's a perfect replacement for my 18 65 0 batteries.

These 3.7V batteries have a long-lasting charge and work well in my flashlight and headlamp.
