Applying area:
Products which their power are less than 100W, like computer book, music CD and work lamp, etc.

Protection:
Overload protection, high temperature protection, short circuit protection, reverse polarity protection.

Auto re-start function:
When the inverter shuts off once it being in protection, it is not necessary to press the switch (on/off), just moving the high loads, the inverter can restart automatically. So there is no need to place the spare fuse.
