UI1 Charger is just a simple single battery charger. It would be better if incorporated with display as its uniqueness where no other charger ever innovate instead of just with 3 LED.
charger was awesome but unfortunately the charging port is micro usb instead of usb C would be better if it was standardise to usb c
recently bought a charger and battery, although the HC33 didn’t work for me but I can still use it for my P10 V2
Compact and USB friendly. Not the fastest charger but helps to get some juice into my batteries.
Easy to use. Need to modify to usb c for more convenience
This is one of the rare USB battery charger that can charge protected 21700 battery. It is compact and light so that it can be conveniently carried around. It can charge a wide range of my batteries from 16340 to 26650 and protected 21700 with a charging current of 1000mA. It is simple to use and does not have a lot of controls, good for majority of users who just want to pop in a battery and let the charger do the rest until it is fully charged.
I have only 1 improvment to share,I would love to see the charging cable change to type C charging cable
