ZDNET reviewer says Topdon JS3000 started his car after months in the trunk

ZDNET's Adrian Kingsley-Hughes says a Topdon JS3000 portable jump starter revived his car during a snowstorm after the unit had been stored in his trunk for close to six months. He found the device, connected it, pressed the boost button and the car started.

The reviewer described the JS3000 as a 3,000A unit built to start gas engines up to 9 liters and diesel engines up to 7 liters, and said that when fully charged the unit should be capable of up to 45 jump starts. He also noted the unit has a light built into the front and that, despite months in varying temperatures, the jump starter showed about 75 percent charge when he needed it.

Kingsley-Hughes framed this as a real-world test of how people actually use such gear: devices are often charged once, then forgotten in a trunk or glovebox for weeks or months. He said short-term review tests are useful but real emergency usage is the ultimate test.

After the incident he said the unit had "earned a top-up charge" and that he will try to recharge it every few months. Beyond his account of this rescue, the reviewer emphasized that reliable emergency gear matters more than short-term test results.
