I have a Noco boost plus GB40 And I'm just wondering what this thing that my usb cable has on it. It's a round thing that opens down the center of it and with it open the USB cable is wrapped once around it then the thing is shut. It looks like it has maginots in it. What is its purpose? Can I remove it?

What is this

It is a ferrite noise filter. It is there to reduce any noise generated by the battery charging circuits to other nearby electronic devices such as radios and other devices that are sensitive to electronic interference.

Hi, the user manual states “The 100% Charge LED will ‘breath’ on/of while charging and will be solid Green when the internal battery is fully charged” - ie the green LED doesn’t flash when the booster is 100% charged. I’ve charged mine many times. Hope this helps.

I have been trying to charge my GB40 for few days now but never goes beyond 25%. Is it defective? Do you charge while it is on or off?

I NEED THE USER MANUAL FOR NOCO GB 40, WERE I CAN DOWNLOAD?

Tommi Burton • 12-2-2021

I am in need of the User Manual for the Noco Boost Plus GB40. I can’t read the user manual included in the box because the print is way too small. I would like the very same instructions but only in a format that I can read. I need to charge it and can’t read the print on how to do that. All the manuals I have been able to find online are for ther “Genius” model. Mine is the one below.
