Is GK-J1201 suitable for my vehicle?

The GK-J1201 suits cars, trucks, boats, buses, SUVs, RVs, lawn mowers, motorcycles, and more, with gasoline engines up to 5.0L and diesel engines up to 3.5L. Designed for 12V lead-acid batteries only, not for other battery types.

What should I do before using the jump starter?

All Green Keeper jump starters come partially charged out of the box but need to be charged prior to first use.

How many times can I charge my phone with GK-J1201？

To determine how many times a 3.7V/10000mAh power bank can charge an iPhone (3000mAh battery), consider power transfer efficiency (60%). A 100% charged GK-J1201 can charge the phone approximately 2 times, accounting for the 60% conversion efficiency.

Why does your product display the peak current on the cover?

Many products avoid printing this to allow flexibility in altering peak current claims on listings. We print the actual, tested peak current directly on the product ensuring transparency and reliable performance.
