Review: Had previously bought cheap versions of these and they did not last and I believe fried a couple batteries! Not worth saving 20.00 on a charger and then having it destroy a 300.00 battery! Noco Pros: compact, lights are very bright easy to read, simple system to use, trust the technology. Not afraid to leave it on indefinitely.
Review: Straight out of the box and put to work.......you need to sort the plug out though, not Aus standard.

*by S***Y on 29 January 2026*

Great product! I use it for my Generac portable generators. Note: Make sure you know what type battery you have. Most generators ship with a standard lead-acid battery. Make sure you select the correct charging type when using the NOCO. (It will remember your setting so you don’t have to do this each time. Only if you change battery types (such as to an AGM battery). Having the “clamps” removable allowing you to screw the connector wires directly to the battery is brilliant and works great! Just connect the charger when storing your generator with the quick connect and disconnect when using the generator. The electric start battery stays charged, ready and healthy 24/7. Highly recommend.
