I wish somebody would sell the real KG41-9-800D,
Verified Purchase(What is this?)
This review is from: Replacement power supply for 9V PURE KG41-9-800D PSU part (Electronics)
I bought this replacement power supply for our Pure One because the wire had frayed on the original and little blue sparks shot out when you turned it on.
We used to get about ten hours of use on full charge. After using this power supply a couple of times battery life went down to less than an hour. I'm used to rechargeable batteries degrading with use but it's usually gradual and not as dramatic as this. Coincidence or a shoddy power supply? I'm still hunting for a real KG41-9-800D so that I can find out.
