Hard to say with the 10m cable need to check with them what Amp rating it is I cant see it it the specs? It needs to be able to handle up to 5 Amps. The thinner it is the less it can handle.

Maybe this will help illustrate what im trying to achieve. >>>>>>>>> Dew heater, Scope & Camera. This should work fine with the 5amp right? The middle cable doesn't need to be any mad fancy type to handle the extra power does it? give it a go Chris, the 5amps should cover it

So just to clarify.... Power supply is works different to a charger? So i defo cant use the 5amp plug from the pic on the left to charge my power tank? It lights up when i plug it in

Personally I wouldnt try to force 5 Amps into it, It may damage the plates inside. With the amount of use your getting I would try and go for just the mains set up

The one on the left is 12 volt @ 1.2amp max. where did you get the 5amps from?
so in theory it should take about 10hrs to charge

changing the plug = it will be a twin core wire, red + positive, black - negative.
the red wire will go to the centre pin/connector and the black to the outer pin/connector

The above is a male plug
same for the female plug, inside the plug will be the same as above

Grab a battery charger out of Tesco they do a small 4 Amp one for car batteries. It will do a far better job plus it has a light to tell you when the battery is ready. I measured what Amps they actually put in and its roughly 2.5 Amps. But the key thing is the voltage is starts at 14 Volts so the battery is forced to take the charge.
The 12 Volt 500ma one you have, the battery will be fighting against it and probably no more than 200ma going in hence it take ages as its just trickle charging and never full.

This thread has me wondering now about my own power supply now and whether it is sufficient or even safe!! I basically plug an extension lead from the mains to the scope. I then plug in my 12V 5amp adapter. Into that I plug in a 4 way cig adapter. Into that I plug the mount power lead and two dew heaters. Now, the thing is each of these 4 sockets have 1 amp written on them. Therefore does this mean my mount is only getting 1 amp when it needs minimum 3 amps? From the voltage side of things, would the dew heaters mean the scope is not getting the full voltage? If so it may mean it is not be getting the minimum 11V required? From the safety aspect, is this set up okay at night when things can get a little damp and even wet from humidity. That last thing I want is to blow up my mount and cameras! Electrocution is one thing but not my scope and cameras!

Electrocution is one thing but not my scope and cameras! Karl think your fine I use an extension lead to go to the scope. If I did have any worry about damp I would just wrap the socket in a plastic bag for the time its out which usually isnt long. The 1 Amp marking is the recommended max current for the cig adapters and to be honest they are being very liberal there they will easily take more than that. Is your power supply sufficient? To work that out you just count up all the Amps your kit is using at any time. With a mains 12 Volt supply the Voltage wont drop it stays the same. Scope draws 3 Amps Dew heater one draws ? (should say in instructions) Dew heater two draws ? Add these up and if they come in under 5 Amps then the supply can power them. If they add to more than 5 Amps then you need a bigger supply ie 6 Amps. (If the dew heaters are rated in Watts, to find the Amps required divide the Watts by 12 Volts, ie a heater rated at 20 Watts divided by 12 Volts = 1.6 Amps) (Another example is car headlight is 55 Watts, car battery is 12 Volts so the current it draws from the battery is 4.58 Amps. ) Hope that makes some sense.

Excellent Carl very clear and thank you. I always put the extension and all power sockets in a plastic box under the scope so it should be fine. I'll try and get the heater info and work that one out but I'm guessing it should be good.

Think the scope only pulls three amps when slewing.and abiut an amp when just tracking....a lot if guys guys use the maplins bench power supply in there obs..I got one at Christmas works a treat. . £45..ok expensive but you have piece of mind its minted for the job.

Hi karl..its maplins £45 one..when I used a heavy duty car battery I sometimes got some power probs gear meshing sounded out clicks ect,, since going with the maplins bench power not noticed prob again..

Guys if you need a good reliable supply that gives you 12 Volts at 12 Amps and you have an old computer lying around there is a power supply in it that screws out and with a simple bit of DIY you have a supply that does everything for free!!
