    The step-up booster arrived in perfect consition in bubble envelope. Heavy and good quality board. The PCB board is attached on a thick plate made of aluminium alloy in order to stick it with thermal past on a heat-sink. Very good value for the money.

    He's back safe for eight days! I tested it, and it works! At higher loads, it requires cooling! Reliable Bolt! I can only recommend it to everyone!

    Not exactly soldered, I'll correct it and then test it. It could work properly.

    The unit works as specified. Max output voltage is 59vdc on a 19vdc input.
