This 12.8 volt /1.5 Amp switching power supply with protective-disconnect plug serves all Celestron telescopes up to the CGEM-DX series, but of course you can use it with most Skywatcher telescopes as well. Some Skywatcher upgrade kits powered with 6V, so obviously you cannot use this PSU with those....
At little higher price the Baader Outdoor PSU offers enormous benefits compared to common department store indoor units.

Conventional power supplies having a 12V nominal voltage are made for use in your "living room". When used outside in the cold the voltage will reduce with temperature. Already at -10°C the remaining voltage output may have gone down to only 10.5 V. The motors of many telescope mounts will behave erratic at such low voltage. Especially the motor driver electronics then tries to replace the missing voltage by draining ever more Amps until both - power supply and mount electronics - will stall or become damaged. Many users then blame the mount and it´s messy electronics - instead of checking whether an inadequate power supply may be the culprit.

The Baader Outdoor Telescope Power supply offers continuous 1.5 Amp/ < 12 volt DC voltage all across the AC voltage range from 90 to 260volt. Even at extreme cold the voltage can not go down as far as to damage the electronic components or motors of your telescope mount.

19 Watt/ 1.5 Amp permanent power ensure ample reserve for smooth tracking even at full photographic instrument load and high torque variations due to changing telescope balance. In addition to the outdoor voltage of 12.8V also the thermal working temperature has been designed for -25°C to +40°C.

The connecting cord measures 2.5m in length. This is longer than usual to ensure that the wall plug portion of the power supply can be safely stored down the tripod legs so that the power cord will not become a trip-wire. The elbowed plug does protect the power cable from accidental breakage and especially the telescope power input socket from damage when actually someone would trip over the cable. When accidentally the cable gets tightened the connecting elbowed plug will release the cable straight, without ripping or damaging the power socket affixed in the telescope.

This item is Baader product number 2457610 but with a UK plug. Picture shows the original unit, but there is a UK adapter in the box as well.

Safety advise:
PLEASE USE AN EXTENSION LEAD WITH SAFETY RCD for your own safety if you decide to use it outdoor at your own risk (!).
We would also recommend to put it inside a much larger transparent plastic box (e.g. sandwich box or shoe box with ventilation on sides, so to exclude any possibility of dew or rain water getting in contact with the adapter for your safety and longer service of the equipment. The above are only personal recommendations that worked for us, but otherwise we can take no responsibility for where and how you use it.
