Works, but not completely. Not fully, but it works.  Adravil: use Liitokala Lii-M4 few months |
* On one hand, I have no complaints about charging Li-ion batteries. NCR18650B charges without any issues.
* On the other hand, I have problems with Ni-MH batteries. You can leave a Duracell AA charging for the entire day, return, see the "END" indicators not blinking and showing 100%, turn off the device, turn it on again, and see that the batteries are only charged to about 50-70%. You can repeat this several times—immediately after turning the device back on or even after a couple of minutes of charging Ni-MH batteries after turning it back on, you will never see 100%. Moreover, if you forget about this and just insert the batteries into a consuming device, the fact that the batteries are not fully charged will be confirmed. A cheap Chinese kitchen clock powered by a Duracell AA Ni-MH battery charged this way works for 1-2 days. With a Duracell AA battery, it lasts several months, up to 6 months. Testing was conducted on 4 of the aforementioned Ni-MH AA batteries taken from one package.
And that's that.
P.S. By the way, the support service at https://liitokala.com.ua/ doesn't care about your problems if the device was not purchased from them. Keep that in mind.
