Test/review of Fitorch 26350 USB UC20R 2000mAh (Black-Orange)

[size=+3]Fitorch 26350 USB UC20R 2000mAh (Black-Orange)[/size]



Official specifications:

• Capacity: 2000mAh
• Voltage: 3.7V
• Charging: micro USB

A 26350 cell with build in USB charging.











Behind the small hole in the black front is a red/green led that shows red while charging and green when done.



The two cell matches fine, but they are not exactly high current cells, it is probably best to stay below 3A.













This is charging with a round cell LiIon charger using 1A current.



This is charging with a USB charger.





[size=+3]Conclusion[/size]

The battery looks good for low current applications, but be aware that the USB charger makes the battery 5mm longer.

The batteries was supplied by Banggood for review.

Very interesting cell size here. I would like to see a 26350 with better performance under load, and without the built in USB recharging.

One of my most used lights is a 2X26650, which is actually a 1X26650 body plus a 26650 extender, which I run with 7.4V incandescent bulbs. A cell like this would allow me to run the brighter 7.4v bulbs without the extender, halving the size down.

I can think of several other different configurations where a quality cell in this size would be useful, Maglite mods being one. Of course, I don't expect any manufacturer to start making quality cells in this oddball size.
