Our take on the Soulor 3000A Car Jump Starters

The Soulor CY20-6 is a portable lithium jump starter rated at 3000A peak and 8000mAh, sold for 12V cars, trucks, boats and RVs. It doubles as a power bank with dual USB ports and has a three-mode LED light (steady, flashing, SOS). It is small and light enough to keep in a trunk, and the clamps carry built-in safety circuitry. Against better-known rivals it is a budget option with a smaller battery reserve, so it suits occasional jump starts and charging phones more than heavy daily use.

Questions and answers

Will it start a diesel truck?
It is rated for most gasoline and diesel engines up to 12V, but the 8000mAh capacity limits how many attempts you get on large diesels. It is best for cars and light trucks.
How many jumps can I get per charge?
Soulor does not publish a jump count. With 8000mAh, expect a few starts on a small gasoline engine and fewer on larger engines, so recharge it after each use.
Can it charge a laptop?
The dual USB ports are for phones, tablets and similar USB devices. There is no AC outlet or laptop DC output.
Does it come with a case and charger?
The listing describes the jump starter, jumper clamps, USB ports and LED light. A carry case and wall adapter are not listed, so check the box contents before relying on them.
Is it safe to leave connected?
The clamps have built-in protection against reverse polarity and short circuits, but disconnect them after the engine starts and do not leave the unit connected long-term.
