4000A Jump Starter for 10L Engines

The WOLFBOX JS24 delivers a 4000A peak current to start 12V vehicles with up to 10L petrol or 10L diesel engines. Its 24000mAh internal battery stores enough energy for multiple jump-starts on a single charge. The unit is rated IP64 for dust and water resistance and includes ten safety protections such as spark-proof, low-temperature and high-temperature safeguards. An integrated LED light provides high-beam, strobe and SOS modes for roadside emergencies.

65W USB-C and QC3.0 USB-A Ports

A 65W USB-C output and a QC3.0 USB-A port let you charge phones, tablets, laptops and other USB devices while away from mains power. The jump starter itself recharges in 1.3 hours when a compatible PD65W charger is supplied separately. This combination turns the booster into a versatile power bank for travel or camping without adding extra bulk.

Suited for drivers needing high cranking power

Buyers who want a compact unit that can start large-displacement engines and keep electronics running will find the JS24 fits the brief. Those who require an included PD65W charger in the box or need wireless charging should look at alternative models that bundle those features.

Questions about this item

How often should the 24000mAh internal battery be recharged when the JS24 is stored for long periods?

Recharge the unit at least once every three months to keep the 24000mAh battery healthy during storage.

What limits how many consecutive 4000A jump starts the JS24 can deliver before it must cool down?

The 10 built‑in safety protections, including high‑temperature protection, will pause operation if the pack overheats during repeated cranks.

Does the IP64‑rated case or the 65W USB‑C port generate noticeable heat or fan noise during all‑day charging?

The JS24 has no fan; the IP64 enclosure and 65W USB‑C port run silently, with only mild warmth during extended use.
