Questions about our five picks.
01Which of these jump starters fits a car, SUV or truck?+
The NOCO Boost GB40 is the compact pick for cars and smaller SUVs within its 6.0L gas / 3.0L diesel limits. The WOLFBOX MegaVolt16 and NOCO Boost GB70 cover engines up to 8.0L gas / 6.0L diesel, while the two MegaVolt24 models extend to 10.0L gas or diesel. Always match the exact engine and 12V starting-system requirements before use.

03What is the difference between picks #1 and #2?+
The MegaVolt24 has a 4,000A peak rating and an 88.8Wh battery for engines up to 10.0L gas or diesel. The smaller MegaVolt16 has a 3,000A peak rating and a 59.2Wh battery for engines up to 8.0L gas / 6.0L diesel. Both support 65W USB-C input and output.
04What is the difference between the MegaVolt24 Air and MegaVolt24?+
