The truck is 24V.
The supplementary information about the car charger is as follows: 1.USB interface: At present, some high-end car chargers generally include 2 USB interfaces, which can charge two digital products at the same time. Such products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, four safety protection functions to ensure safe use. Car charger in the car at the same time, but also home, to achieve car charging, direct charging, USB charging three-in-one multi-functional use.
The input voltage of the car charger is 12VDC, the truck is 24VDC, the output is 220V AC, and the instantaneous current of 0.3 seconds is 150-300A. The normal voltage of the truck is between 25 and 28v. The truck uses two batteries in series, and the voltage when running should be about 27v, and it should be normal at about 26V after parking for a period of time. Battery voltage should be no-load voltage is about 26 volts, load voltage is not less than 22 volts is normal, lower than this voltage may be difficult to start.
