It can save you from waiting on roadside assistance, flagging down another driver, or digging out jumper cables when a battery dies. That makes a cordless jump starter useful for summer road trips, long commutes, airport parking, camping weekends, and getting ready for cooler fall and winter mornings a few months from now.Thanks to this flash deal we found at Walmart, the Soulor Car Battery Jump Starter is on sale for $28, more than half-off its normal price. It's listed with 3,000A peak current and is designed for 12V vehicles with gas engines up to 6.0 liters or diesel engines up to 3.0 liters. That covers a wide range of cars, SUVs, motorcycles, trucks, and vans, making it a solid item to keep in the glove box, trunk, tool box, or emergency kit.Soulor Car Battery Jump Starter, $28 (was $57) at WalmartSoulor Car Battery Jump Starter, $28 (was $57) at WalmartCheck PriceProsCompact enough to keep in a glovebox or trunkLCD makes it easy to check remaining battery levelBuilt-in flashlight with various modes helps with emergency situationsConsOnly rated for diesel engines up to 3.0 liters8,000mAh battery is smaller than some other jump starters on the marketAdvertisementAdvertisementThe compact design is a big part of the appeal. It measures 7.0 inches tall, 3.5 inches wide, 1.5 inches thick, and weighs about 0.77 pounds, so it won't take up much space in the vehicle. It comes with an 8,000mAh capacity and is designed to jump-start a vehicle up to 30 times under ideal conditions. The built-in LCD screen shows the battery percentage, which is helpful because a jump starter only works if you remember to keep it charged. It also has a three-mode LED flashlight with normal, strobe, and SOS settings for low-light emergencies, outdoor use, and roadside situations. The package includes the jump starter, jumper cable, type-C USB cable, and user manual. For dead batteries, road trips, daily driving, and seasonal emergency prep, this is a cheap tool that can save a lot of hassle.Related: Every Trunk Needs a Portable Jump Starter, So You Should Grab This One for 70% Off at AmazonOne buyer said, "[It's] easy to use, starts the car quickly, and the battery display is clear.
