#502 LiitoKala Lii-202 Smart Charger

Quick teardown and review of the Lii-202 18650 charger and power bank.

Build

Notes

I wanted a general purpose 18650 charger and picked up the LiitoKala lii-202. It seemed like a good deal because it included 2x ICR18650 2600mAh batteries, and it included a power bank function in addition to supporting a multiple charging modes for a range of Lithium and Nickel Metal Hydride batteries.

I’ve since found a very good review with detailed performance tests. Overall it is a good unit, although the power bank function is a bit of a gimmick (only runs from one battery, and the output is a bit noisy).
