Hello,
I recently received a motorized telescope that runs off of 8 AA batteries. A power adapter is available but I have yet to find one available and my local telescope stores. The power requirements, as stated from the manual, are: 12 VDC, 750 mA (tip positive). I found a power adapter lying around at home that has printed for output: 12 VDC,
1.2 A (tip positive). First of all, if this power adapter is outputting the listed amount of power, would it be safe to use on the telescope? I pulled out my voltmeter and measure the output power of the adapter, and it hovered around 16 VDC. I tried some other power adapters around my house and they all seemed to be reading more VDC than was printed on the adapter itself. Is this normal? Or is my voltmeter just screwed? I measured the VDC from the 8 AA battery pack and it came up with about 12.2 VDC, which makes sense seeing as how each battery is 1.5 VDC.Any help would be greatly appreciated! I don't want to hook an adapter up to my telescope that might fry it!
Thanks! Derek
