[stuffedhaggis]

Guys looking for a cheap power tank of Amazon to use with my new Goto Scope and mount ,

Which of these would work ok .

Silverline 234578 900 Watt 12 Ah Jump Starter and Air Compressor

Universal Jump Starter: 300 Amp

PORTABLE POWER STATION / ENGINE JUMP START c/w AIR COMPRESSOR

Hi

What you want is Ah, and I see no specifications on all of these except the Silverline wich has 12Ah. This would be enough, but you should be able to find better ones. If I had to pick one of these, this would be the one for that simple reason. But again, the weight seems a bit low as it states item weight 3kg and boxed weight 13kg. Wut?

The Universal one is too light. Wont have enough battery on board with just 3kg. The Portable Power station has horrible reviews. Therefore I wouldn't recommend either of these.

I would recommend you look around a bit more to find a 17Ah one, this should be enough to power both mount and a heatstrip on mid power for the duration of the evening. You could get away with less, but not for those extended marathon sessions.

they will all work ok. the reviews for the 3rd one should tell you something about the quality of these things though

if you do get one make sure you keep it charged and try not to discharge it below 50% when using it

Check out maplins mate , got mine from there for £25 and it does what I need no probs , if you want to run other bits as well then you will need something bigger

[cantharis]

Mine is a Maplins 17Ah - didn´t cost a lot and certainly does all I could want for my EQ5 Synscan.

I have had this one for a couple of years and it works a treat. I charge it every few weeks and after every use.

Ive just brought one from maplins as advised by FLO for £25, this will be running my SW 150P-DS & EQ5 PRO GOTO, they advised this should be good for a good 3hrs of observing.

Lots of extra bells and whistles but still just the 17 Ah.

I picked up a 26 a/hour sealed battery that would have been for a golf cart and paid £15, ideal

I like the look of the mid Maplin unit. 17Ah (and a compressor to blow up your comfy chair) but the stock checker says they are all out...

I had been looking at a specific PowerTank but will take the advice here and nab one from Maplin.

Have you thought about makng your own power tank. There are some well documented power tank projects in the diy section.

Exactly! Maybe a bit more often than annually but you don't worry about running out of power

imho, the power tanks are a cheap and nasty heap of junk build down to a price so the cheapest components are used with little or zero quality control. At the core of them is a piddly little battery that on a good day is 17Ahr but probably nearer 10Ahr with an awful mains charger that may or may not charge it. All you need out of the yellow perils is the battery all the rest is plastic scrap which you pay for.

Investing in a proper deep cycle battery and a proper battery charger/conditioner which will last 5+ years is the most economic and reliable way to go.

A very important point there, a poor quality charger will shorten the life of even the best battery
