### ⭐⭐⭐⭐⭐ Good charger
*by M***Y on 15 January 2026*

Bought as my daughter lost the charger for her 3d printing pen. Build quality is goodand having multi power dial makes it great for everything.

### ⭐⭐⭐⭐ Flexible power supply, just beware of the polarity!
*by M***M on 3 September 2025*

Needed to replace a power supply for two different devices, ones which I only use occasionally, but need an external power supply to work, so bought this. The selection of tips is great, as is the reverse polarity adapter, although I would say it would have been better to have a physical switch on the main PSU to reverse the polarity rather than the adapter cable. It you forget you have the adapter installed, you run the risk of damaging the equipment you intend to power. You have to look at the main unit to set the voltage anyway so a switch for polarity would have been helpful. Works well and luckily didn't need to power anything below 3v as this is the lowest setting.
