YESPER Car Jump Starter, 2000A

The built-in air compressor gives this YESPER jump starter a second job: it can help with a low tire as well as a dead 12V car battery. The unit combines a stated 2000A peak current with a 150 PSI compressor, an LCD showing battery level and operating status, and an auto-stop feature for inflation. That mix is useful when you want one portable emergency device rather than separate tools. The tradeoff is that it also needs care between uses, and its charging adapter is not included.

Where it shines

The practical appeal is having jump-starting and tire inflation in the same box. If a tire needs air before a drive, the compressor has four preset modes and three nozzles for cars, SUVs, bikes, and balls. The maker says it can inflate a car tire to 30 PSI in three minutes, actual results can depend on the tire and conditions. Auto-stop is a helpful detail when you’re topping up a tire: set the target and watch the LCD rather than trying to judge the pressure by eye.

For a roadside battery issue, the unit is designed for 12V vehicles and lists support for engines up to 8.0L gas or 6.0L diesel. According to the maker, it can provide up to 20 starts, though that figure shouldn’t be treated as a guarantee for every vehicle or situation. It also has a USB output for charging a phone or tablet and a light with flashlight, strobe, and SOS modes. Picture keeping it in the car for a trip, then using the light while connecting the clamps after dark, it’s a more self-contained approach than carrying a jump pack alone and a separate inflator.

Quick overview

The unit weighs 635g and includes smart battery clamps, a pump tube, a multifunction gas nozzle, and a phone adapter cable. The LCD reports remaining power and working status. Listed protections include reverse polarity, anti-spark, low voltage, overheating, and overload, with indicator lights for correct or incorrect connections.

It’s a great fit if you want one device for occasional jump-starting, tire top-ups, and basic emergency lighting. If you prioritize the smallest possible battery-only jump pack, the compressor and extra functions may be more than you need. The USB output is rated at 5V/2.1A, and the package does not include a charging adapter, so plan around that before relying on it as a ready-to-use kit.

How to take care of it

If the jump starter sits unused for a long stretch, the instructions recommend charging it every three months. The listed working temperature range is -4°F to 140°F, the maker warns against using or storing it for extended periods in high temperatures. It also advises against repeated jump-starts at high frequency and calls for at least one minute of cooling between starts. Those limits matter if you expect to handle several vehicles in a row: this is an emergency tool, not a substitute for a high-volume compressor or repeated-duty shop equipment.

Should you buy it?

The YESPER is worth considering if you want jump-starting, tire inflation, a USB output, and emergency lighting in one portable unit, and you’re comfortable keeping it charged and following the cooling guidance. It’s not for you if you need a charging adapter in the box, plan on frequent back-to-back starts, or would rather carry a simpler jump starter and choose a separate inflator for heavier use. The deciding factor is whether the compressor and extra functions will earn their space in your vehicle.
