The Wolfbox MegaVolt24 is a 12V lithium jump starter rated at 4000A peak with a 24,000mAh battery. Wolfbox says it starts gasoline and diesel engines up to 10L, which puts it in the heavy-duty class rather than the pocket boosters sold for sedans. It also works as a power bank through a 65W USB-C port and a QC 3.0 USB-A port, and has an HD display plus an LED light with high-beam, strobe and SOS modes. It suits drivers of large SUVs, trucks and diesel vehicles who want one pack for jump starts and device charging; it is bigger and heavier than compact boosters, and the high output is more than a small car needs.
