M5StickC and 18650C endurance

I use a USB type watt meter. Please see below.

@liemph Ah, nice device. Been searching the internet and found one brand with interesting devices (even with blue tooth data gathering) but the shipping costs are ridiculous. Could you tell me what brand you have. Makes searching less difficult.

Those usb meters are so useful. I use a kewize one

kewize
Can you be a bit more specific? I can not find any information with that name.

@kees I bought with the brand Keweisi from Aliexpress a long time ago (same with the one mentioned by @ajb2k3 ?). But I could not find now. However, I found a very close one in Aliexpress:
10 in 1 Digital Dispay DC USB Tester Current Voltage Charger Voltmeter power bank wattmeter voltage tester doctor detector (462 Japanese Yen + 12 Yen Shipping to Japan).

I own 2 as I had two usb items running on a solar system.

@crami25 the question was not related to the M5Stack but to the M5StickC. And most powerbanks will only work for a few minutes. this because the current is to low and the powerbank will cute off the power.
I can confirm this behaviour with a RAVPower bank, I have tried to power low current sensors with it and it was a failure due to the cut off.

@Pepsi Thanks, I could not find the call to decrease the speed. Not very much, but it helps.
