The TOPDON JS3000A Car Jump Starter with Stop Spark Sensor is a lithium pack the listing rates at 3,000 peak amps, from a vehicle diagnostics brand, and it takes tenth place in our jump starter ranking. It was GBP 119.98 when we collected the listing. Everything on this page comes from that listing rather than from our own testing: the price, the specification table, the spread of its customer ratings, and two review quotes copied word for word. We placed it tenth as the professional-leaning pack in the group; the listing's own highlight line names an LED flashlight and the 24,000mAh battery, which suit someone who jump starts often rather than once a year.

The most telling figure is the weight. The table gives 2.26 kg, the heaviest pack in our ranking and five times the 454g of the NOCO GB20, so this is a boot item rather than a glovebox one. Two other details are worth a look. The table prints 3,000 amps twice, once as peak output current and once as plain amperage, so read 3,000 as the peak. And the ratings have an unusual shape: two stars, at 4%, is more common than four stars, at 3%, on a base of only 127 ratings.

## Questions people ask

**Will the TOPDON JS3000A start a diesel?**

The listing covers engine size in one line, and it reads "for 9.0L Gas or 7L Diesel Engines". Gas is the American word for petrol, so that is 9.0 litres of petrol or 7 litres of diesel, from the 3,000 peak amps the table gives. TOPDON publishes no other engine figure.

**How many amps does it actually deliver?**

The specification table prints 3,000 amps twice: once as peak output current and once as plain amperage. The same number in both rows points to 3,000 being the peak figure rather than a sustained one. Neither row is something we measured.

**How big is the battery?**

The table gives 24,000 milliamp hours of lithium ion. The listing does not publish a USB output rating or a number of starts per charge, so we cannot tell you what else it will run or how many jumps you get between charges.

**How heavy is it, and will it fit a glovebox?**

The table gives 2.26 kg. That makes it the heaviest pack in our ranking, five times the 454g of the NOCO GB20, so plan on the boot. The listing publishes no dimensions at all, so we cannot quote a size.

**What vehicles does the listing say it suits?**

Compatible vehicle type is given as ATV, Motorcycle, Passenger Car, SUV and Truck. Together with the 9.0 litre petrol and 7 litre diesel figure, that is the whole of what the listing states about fit.

**What does the listing say about safety and approvals?**

The specification table has a row reading "Specification Met: UL", and the product name carries a Stop Spark Sensor. Both are what the listing publishes: it gives the label and the name, not how either was tested, and we make no claim about certification.
