Rank #6 in Best Jump Starter 2026: 10 Car Battery Boosters Ranked
WOLFBOX MV24 Jump Starter Power Pack, 88.8Wh, 65W USB-C, LED Display
Price and rating as shown on Amazon when we collected them. Both change.
The WOLFBOX MV24 is a 4,000-amp lithium jump starter that ships with a 65W USB-C wall charger, and it takes sixth place in our jump starter ranking. Everything on this page comes from its Amazon listing rather than from our own testing: the GBP 129.99 price, the specification table, the spread of its 5,820 customer ratings, and two review quotes copied word for word. The listing sells it on that screen: an LED display that shows charge as a number rather than a row of lights.
One line of the specification is worth a second look. The table gives the battery as 6,000 milliamp hours, while the Item Highlight field on the same page gives 24,000mAh and 88.8Wh. The two capacity figures sit a factor of four apart on the same listing, so the watt-hour number is the one to carry over when you compare packs. Two other fields read oddly as published: the listing claims cover for 10 litres of petrol and 10 litres of diesel, and its Specification Met field reads simply true, with no standard named.
How those 5,820 ratings break down
An average hides its own shape. This is the spread behind the 4.6 stars.

Questions people ask
What size engine will the WOLFBOX MV24 start?
The Item Highlight field on the listing claims 10 litres of petrol and 10 litres of diesel, from 4,000 peak amps. That is a very large diesel figure for a pack this size, and it is the listing talking rather than a number we measured.
How big is the battery?
The listing gives two answers. The specification table says 6,000 milliamp hours; the Item Highlight field on the same page says 24,000mAh and 88.8Wh. We report both because both are published. The 88.8Wh figure is the one that compares cleanly with other packs, since milliamp hours mean little without the voltage behind them.
How much current does it actually deliver?
The listing gives 4,000 amps twice, once as Peak Output Current and once as Amperage. Both fields carry the same number, so the specification publishes no separate continuous rating.
What comes in the box and how is it charged?
WOLFBOX lists the MegaVolt24 jump starter itself, a 65W USB C wall charger, a USB C to USB C cable, the jumper cable and an EVA pack.
How heavy is it and will it fit a glovebox?
The specification table gives 1.36 kg and 9.8 x 23.7 x 3.8 centimetres. It is flat and long rather than chunky, at 23.7 centimetres long and only 3.8 deep it is flat rather than chunky, though the listing does not say whether it fits a glovebox.
What warranty does it come with?
The listing states a 2 year manufacturer warranty. Its Specification Met field reads simply true, so no standard or certification is named on the page at all.
