4.Damaged USB Charging Cable

A damaged USB can also be the reason why the jump start is not charging. These cables tend to be strong with a long lifespan. However, they can get damaged with frequent use

5.Dirty USB Port 

If you store your NOCO GB 70 in your garage where it is exposed to various liquids and lubricants, the USB port may have accumulated some of it. Therefore, it is important to examine it for any corrosion, dust, or grime.

Usually, starting a car takes a lot of energy. This means that you will be burning a lot of stored energy on the jump starter. With that in mind, it is important that you recharge it after each use even if it has not been used for three months to avoid over-discharges. 


As an indicator of a fully charged battery, the 100% charge LED turns on. It will go off if the battery is slightly less than 100%. When fully charged, the green LED will be solid. It turns off if 25%, 50%, and 75% are full.
