Exactly what I needed, now my solar panel is charging the battery
I had a 2.1mm DC cable going from my Renogy solar panel to a Golabs battery station. It wouldn’t charge. I determined that the cable was the wrong polarity. This adaptor has swapped the polarity and now the battery charges. Very pleased with this item 😁

Useful add on to Zolt PSU
Goes with the Zolt multi-voltage power supply. Needed as the only thing the supply doesn't do, is cater for the odd thing that uses a negative center pin

This is a 2.5mm NOT a 2.1mm adapter, will not fit
Beware! NOT a 2.1mm adapter, it's a 2.5mm adapter. Bought specifically to power a device which requires a 2.1mm adapter, I already had a 2.5mm which didn't fit, this is exactly the same as my existing 2.5mm Absolutely avoid if you need a 2.1mm rather than 2.5mm adapter, this is not as described
