Q: Dos e it come pre charged to jump battery
A: The jump starters are shipped with some charge, but it’s best to fully charge the unit before first use. This ensures you get maximum performance and safeguards the battery health.
submitted byLauren - 2 months agoA: The one I bought had 83%… instruction manual says it must be at 80% to work but preference is 100%. I would imagine the charge percentage depends on how long it has been on the shelf. I changed to 93% before trying and it worked like a charm.

Q: How many times can it charge a phone on a single time being charged
A: It depends on your phone’s battery capacity, but with 8000 mAh of stored energy, you can expect approximately 2 to 3 full charges for a typical smartphone (3,000–4,000 mAh capacity). Results may vary.

Q: Can this unit be used as a trickle charger for a 12v battery also?
A: No, this unit is designed for jump-starting (high-current bursts) and as a USB power bank—not as a continuous trickle charger. Using it as a trickle charger might strain the internal electronics.
