Will it start a semi-truck?

Topdon rates it for 12V gasoline and diesel engines up to 16 liters, which covers semi-trucks and trailers. It is not intended for 24V systems.

How many jumps per charge?

Topdon claims up to 45 jump-starts on a single charge. Real counts depend on engine size and temperature.

Jump-starting works without it. The battery test and status monitoring run through the Topdon app.

Can it charge my phone?

Yes. It has USB fast charging, and Topdon says a smartphone can recharge in about 25 minutes.

Is it too big for a car?

It works on cars, but it is sized for trucks and large engines. A smaller pack is easier to store for a compact car.

About the V4500Plus

The TOPDON V4500 Plus is a 12V jump starter for gasoline and diesel vehicles with engine displacements of up to 16 liters. It has a peak current of 4500A and is meant for large vehicles such as semi-trucks and trailers, as well as off-road vehicles and boats. One charge provides up to 45 jump-starts.

Boost mode is for stubborn batteries. It keeps current flowing for three minutes, which allows multiple start attempts. Paired with the app, the unit also works as a battery tester.

The 120Wh battery doubles as a power bank. It has a bidirectional PD100W Type-C port, two USB QC 3.0 ports and a 12V DC output, which can power on-board equipment such as refrigerators and dash cams. The unit has 15 LEDs that give up to 500 lumens, plus 6 red warning lights. The casing is IP65-rated, and the cables are heavy-duty copper.
