How to Maintain Your NOCO GBX55
If you own a portable jump starter or are considering getting one, it’s crucial to understand how to keep it in top-notch condition
- Regular Inspection for Optimal Performance of Your GBX55 Car Battery Jumper
- Proper charging is crucial to maintain the functionality of your NOCO GBX55 car battery jumper.
- Storage. Proper storage is equally important, especially if you don’t use your GBX55 frequently.
- Regularly testing your jump starter ensures that it’s in working condition when you need it.
- Whenever possible, store your GBX55 portable jump starter in a moderate temperature environment between 50 ºF – 70 ºF. Like vehicle batteries, exposure to extreme temperatures is detrimental to jump starter batteries, both in the short term and long term.
- Respect the cycles. Every jump starter is subject to a duty cycle in which the vehicle can be cranked only so long before a period of rest is needed. For almost all jump starters, the recommended duty cycle is between 5-6 seconds of cracking followed by 3-5 minutes of rest.
- Clean clamps. A battery in poor condition may have battery acid on the posts, so wiping down the clamps after jump starting a vehicle always is a good practice to keep the clamps from becoming corroded

NOCO Boost X GBX55 User Reviews
Nuno Miguel Alves – ★★★★★ (5/5)
Excellent product!
I was already a user of a lower-range version of this product and was quite satisfied, but this upgrade has made me like it even more. The car starts right away without any issues. For fast charging, I use the 60W charger from my MacBook Pro, and it charges in about 1 hour. I recommend it!
Kikechdez – ★★★★☆ (4/5)
It worked on the first try!
It came with some battery, and it started a Porsche Boxster on the first try, so far, so good. The issue is that it comes without a charger. It was connected to a mobile phone charger all night and didn’t charge at all; the exclamation mark even appeared in the morning. It’s illogical that if it doesn’t easily charge with any charger, you sell it without one. I bought a charger separately, but it doesn’t have a delivery date, so that’s a downside in that regard.
Felix – ★★★★★ (5/5)
