But there are many kinds of car jump starter, such as metal and ABS, which is good?

No matter what material, the power supply must meet the temperature resistant and flame retardant requirements, if the jump starter for car internal short circuit or failure, can be a good protection of the user.

It looks good on the surface of the metal case and is completely flame retardant. However, in the process of use, it is likely that the metal shell will be conductive, the power supply is short-circuited or burned, even the safety of the owner and the car insurance are threatened, so it is still a good choice.

Ordinary plastic, when the car jump starter is short-circuited or the fault produces high temperature, it will be damaged or even melt directly, threatening the safety of the owner. In contrast, the ABS plastic shell has good insulation, high and low-temperature resistance, and has excellent impact resistance, and can be fully competent for the car jump starter. The use of the power supply.
