A portable jump starter is one of our mechanic’s must-haves, but it’s also one of the smartest emergency items any driver can keep in the car. 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.
51% OffPros
- Compact enough to keep in a glovebox or trunk
- LCD makes it easy to check remaining battery level
- Built-in flashlight with various modes helps with emergency situations
Cons
- Only rated for diesel engines up to 3.0 liters
- 8,000mAh battery is smaller than some other jump starters on the market
The 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.
One buyer said, “[It’s] easy to use, starts the car quickly, and the battery display is clear. Compact size but plenty of power, plus the USB and LED light are very handy.”
Another happy shopper commented, “This jump starter is very small and light, just like a power bank. It is a lifesaver in an emergency.”
