Well, I got a response from NOCO. The response I got from them, makes me believe the GBX35 (Costco NOCO) is generic version of the GBX45. Specs are the same, internal guts are not. If that makes sense.
Here is the responses from NOCO:
Hello,
Thank you for contacting NOCO Support.
The GBX35 jump starter that is available at Costco is a special unit manufactured for that reseller in particular. While it does not have a direct equivalent to any of the models on our website, its performance would be comparable to that of a GBX45 (
https://no.co/gbx45).
Sincerely,
Steve | Customer Support
I then replied and ask the following:
So, what you are telling me or not telling me, is that even though the numbers are directly comparable between the GBX35 and GBX45. They are different.
Is the internals DIFFERENT???? If so how are they different???
The response from NOCO:
They have the same internal specs.
