Input:100-240VAC,50/60Hz,1.2A Output:42V--1.5A, mini 3 prong connector show:"1"means "+", "2" means "-", “3”means ground, The plug's Diameter is 8.8mm(0.31in), please check the size before order.
105℃ Output capacitor, global applicable AC Input voltage.100% full load aging test, Internal EMI filter, ripple minimum. The precision current between ±0.1A, the voltage tolerance is ±0.1V, absolutely not virtual marking.
The charger Built-in simply fan, with radiating fin surrounding the board, dissipating the heat through the shell, So some hot on the shell when charging is very normal, but it is durable.
The Charger protected: Short circuit protection/ over current protection/ over voltage protection; red light -- charging, green light -- charge OK, it stop automatically when the battery is full.
To make your batteries last 10X longer, avoid using batteries below 35% and don’t charge above 85-90%. Replace your broken charger or add an extra charger to charge in 2 locations without taking the original charger with you
