The WZHMSJL 1500A is a compact lithium jump starter that claims 1500A peak current and a 37Wh, 45C-rated battery. It is built for 12V vehicles and is rated to start gasoline engines up to 6.0L and diesel engines up to 3.0L, though the product name lists smaller figures. It also works as a USB power bank and a three-mode LED flashlight, and it weighs about 1.4 lb, so it stores easily in a trunk or travel bag. Against lead-acid booster packs it is far lighter and needs no wall charge before storage; against better-known lithium brands, its safety electronics and clamp quality are unproven.

This is a portable 12V lithium jump starter with a 1500A peak current. It uses a 45C high-rate lithium battery with 37Wh capacity. It can start gas engines up to 6.0 L and diesel engines up to 3.0 L, and it works with other 12V vehicles such as motorcycles, cars, SUVs, pickups and lawnmowers. The peak current helps start low-voltage and fully drained batteries.
It has 8 built-in protections: reverse polarity, reverse connection, overcurrent, overvoltage, overload, overcharge, over-discharge and short circuit. It also works as a portable power bank with USB charging. An LED flashlight has 3 modes: flashlight, strobe and SOS.
The unit is compact and lighter than bulky lead-acid jump starters, so it fits in a car or travel bag. Keep it away from high temperatures. Make sure the positive and negative terminals do not touch, and avoid continuous or frequent start attempts. In winter, store it at a proper temperature and avoid charging or using it in extreme cold. Check the manual before use.
