Swapping flashlight/shaver batteries with a handheld

90-second unboxing of the H1 portable spot welder: the creator’s old welder built from a microwave-oven transformer was too bulky; the new unit is very light, sits well in the hand and charges over Type-C. In the box: charging cable, nickel strip, welding pins, manual. He will test it tomorrow

The creator’s home-made spot welder, built from a microwave-oven transformer, was too bulky to carry around; today a portable spot welder arrived, and it is very light. Opening the shipping carton reveals a long black AWithZ box (H1 label), nicely packaged; the black cylindrical body sits well in the hand, with a Type-C charging port on one end and a power switch; the box also holds a charging cable, nickel strip, welding pins and a manual. He will try it out tomorrow. Comments: some ask how such a small battery can spot weld at all, suggest opening it up to see what battery is inside, or say it won’t last; one user says they bought this AWithZ unit before and the welds were rock solid, and after the power was bumped up they also bought the supercapacitor model UF20B.
