How many ports on a USB charger would be perfect for you?

One function I’ve never found in any powerbank is the ability to charge low power devices. I have hearing aids and a small bluetooth device that streams audio from my phone and tablet to my hearing aids. It small so has a small battery with which only takes a few mA to charge. Powerbanks just switch off at such small loads.

The new Xiaomi 10000mAh power bank with QC can.

double click the button allows low current devices to be used, previous models switched themself offf below 0.07A, so the dimmable USB LEDS didn’t worked in moonmode and also it wasn’t possible to charge small batterys on smartwatches and rc helicopter so well

The YZXStudio power bank also has a user configurable auto off current.

2. Sleep current threshold. Under this the powerbank will shut down after a set period, see next setting (0.01-2.55 / off)
