Well according to the description on the U.S. shop page it does have short protection. So my guess would be if it detects a short it will prevent the device from working
Underneath its bombproof shell, the Booster is packed with a comprehensive array of circuitry like short circuit protection, over current protection and under voltage protection. Even when used constantly at maximum setting, the time between battery charges is only reduced by 25%. It will work with mods that use 18500 or larger sized batteries and IMR low drain batteries, providing the correct adapter is used to fit the Booster to the device.
Oh my god, I am struggling to understand english, I didnt realize I need to understand electricitian as well
"Packed with a comprehensive array
of circuitry" = a lot of electricity parts in it
"short circuit protection" = this one I think I know, prevention of shorts
"over current protection" = Is this "spike" protection, to much at the same time like protection from a thunderflash?
"under voltage protection" = Is this somekind of backup system that accumulate "electricity" in case it is to low it will put it up
I am just kidding, better not trying to explain to me. There is two problems, I dont understand the english and even the explanation might be to difficult for me
So in short my thought was correct, the booster will protect the machinery against evil smokys?
