Weighing under a pound, it’s highly portable and supports 6.0 liter gasoline engines and 3.0 liter diesel engines. It includes a built-in LED light and a power bank, though its lifetime is modest compared with premium units.

Wolfbox’s 4000A jump starter is priced at $109.99 (35% off) from $169.99. It combines a jump starter with two built-in charging ports and an LCD readout. The unit handles most gas and diesel engines under 10 liters, with an LCD that tracks battery status. It charges in about 90 minutes and includes a USB-C port, a USB-A port and an LED light with SOS and strobe modes. It’s designed to withstand a wide range of temperatures.

Gooloo’s A3 jump starter with an air compressor runs $69.98 (36% off) from $109.99. It supports 12V batteries and works in temperatures from -4 to 140 degrees. A boost button activates a stronger jump, and the built-in cordless air compressor can inflate eight tires on a single charge. There’s also a power bank and an LED flashlight.

DB Power’s Peak 3000A is the budget choice at $39.48 (51% off) from $79.99. It can jump start a vehicle up to 30 times per charge, and includes a compact design that fits a glove box. The LCD shows remaining power and there’s a compact compass built in for emergency use. A single USB port charges devices quickly.

DeWalt’s 1,600-amp jump starter with a compressor and power bank is $143.99 (10% off) from $159.99. The unit adds an alternator tester, an alarm to alert if clamps are reversed, an air compressor with auto shutoff, and USB-A and USB-C ports for device charging. The overall package is larger but well suited for weekend work or roadside maintenance.

When shopping for a portable jump starter, buyers should consider engine size and typical use. For most cars and SUVs, 800–1,000 amps suffices; trucks, RVs and diesel engines may require 2,000 amps or more. Most units offer between 15 and 40 starts per charge. Look for safety features such as spark-proof clamps and a reverse-polarity alarm. Portable jump starters avoid needing another vehicle, which can be a practical advantage in roadside situations.
