## Description

Portable Car Battery Jump Starter: 3000A Battery Jumper Pack for Car Engines Up to 8.0L Gas/Diesel, Ultrasafe Jumper Box with Jumper Clamps & Emergency LED Lights, Power Bank with PD65W Quick Charge : desertcart.co.uk: Automotive

Review: Multi function and great! - Really good bit of kit! Cheap for me in sales but I would pay full price it’s worth it! Fits under my seat, charges in couple hours, seems to last but I don’t need to use it only for emergencies, torch light is handy! All rounder works. Easy to use.
Review: Works really well. Excellent piece of kit and great value. - Just had a chance to use it for the first time this morning, on someone else's car. It was very simple to connect up and the car with the gutless battery started first time. Very impressed and pleased that I had it. I bought this neat little device to carry around in my EV just in case the 12v battery on that failed (which it never has) and also so that I could jump start other people's cars (I always carried jump leads in the past for this reason, but the EV's 12v battery can't be used with those). I've yet to try starting a car with a completely discharged battery but that seemed like a pretty important feature when I was considering which jump starter to buy. Pros: Simple to use, plenty of power capacity, seems to be solidly built, packs into a tidy little case, has potentially useful additional features (emergency light, powering coolbox, charging phone etc), holds its charge for a very long time when not in use and is very good value for money. Cons: None

## Questions & Answers

**Q: How to jump start?**
A: 1. Insert clamps into the EC5 port. 2. Securely connect clamps to battery terminals. 3. Start engine within 30 seconds when the light is green. 4. Disconnect clamps promptly after starting. *Ensure the Jump Starter battery volume is above 50%.

**Q: Is GK-J1204 suitable for my vehicle?**
A: The GK-J1204 suits cars, trucks, boats, buses, SUVs, RVs, lawn mowers, motorcycles, and more, with gasoline engines up to 8.0L and diesel engines up to 8.0L. Designed for 12V lead-acid batteries only, not for other battery types.

**Q: What should I do before using the jump starter?**
A: All Green Keeper jump starters come partially charged out of the box but need to be charged prior to first use.

**Q: How many times can I charge my phone with GK-J1204？**
A: To determine how many times a 3.7V/20000mAh power bank can charge an iPhone (3000mAh battery), consider power transfer efficiency (60%). A 100% charged GK-J1204 can charge the phone approximately 4 times, accounting for the 60% conversion efficiency

**Q: Why does your product prominently display the peak current on the cover, while others don't?**
A: 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.
