I looked around at possibly a new Powertank and found this.

Yes it really is not much bigger than my mobile phone if a fair bit thicker.

It has a good LED torch built in to annoy folks at star parties  but no red light.... mind I always found the powertank difficult to balance on my head when observing so use a head torch.

Is it man enough to do the job???

well correct me if I am wrong but the charge is bigger than the large powertank I had. AND its designed to jump start your car....... WHOOOOOHHH

It comes with car Jump leads, a 12V out socket (.... yes only one but it will take a double adapter) , two USB leads to fit its 2 USB charging ports and a very sexy case.

It was also a lot cheaper.....

What do you guys think, anyone used one yet. I will let you know when darkness returns.

Clear DARK skies.

Very interesting find, its suitability depends if it's a deep cycle battery or not, in other words will it discharge under demand over a period of time and recharge ok over many cycles, time will tell.

Looks a good way to go, LiFePO4 and think I have seen this type of thing on SGL before.  How long to recharge ?

I.used lipos on my rc stuff, been great if you review it after a night under stars running a mount and camera with cooler or dew controllers, I wonder if you could put a 3 way socket on or more?

According to the specifications it is only 57.6W/h, at least it claims to use LiFePO4 batteries.

I use one of these:
https://www.amazon.co.uk/20000mAh-Multi-Voltage-Portable-Notebooks-Compatible/dp/B00BUJCMUQ/ref=cm_cr_arp_d_product_top?ie=UTF8

Which is a similar size but is 74W/h but I don't need very high peaks of power with my kit.

Very interesting unit - thank you for posting it.

Me thinks I'll do a bit of hunting to see if it also live over here.

Over & Out -

It's either 'Over' or it's 'Out' - it can never be both !!!

Its something that really irritates me in war films, submarine movies etc etc ;-)

Well if its got the same sort of tech onboard as my mobile phone charger you might be pleasantly surprised.  I got mobile phone boosters last year.  About as big as 3-4 packs of playing cards and a fair weight for its size it reckonned it gave 18000mAhrs.  All I know is it did stirling service keeping the kids two mobile phones charged for a whole week.  The only draw back is from fairly empty it can take over a day to recharge!   However it is that good that I got anothet for my bro to take to festivals!

      Hello Everyone!

      This is my first post to SGL, but it's certainly not my first visit. I've been a reguar leech to the wealth of information on here and have amassed a plethora of equipment for exploring the night sky that evolved from an 8" 200P Dobsonian, and finally up to its current "Mark IV" as the 8" Newtonian Equitorial you can see in the photo. I'm aware of the ettuiqette here, and this isn't a "hello" post, no.

      This is me sharing my write-up for the 12v Power Supply that I made myself in the eventual journey to my fully remote observatory (hopefully opening 2018) at the end of my garden. Hoping to maybe give something back to the community that i've taken so much knowledge and tips/tricks from over the last 18months; because 19months ago, I'd never even put my eye to a telescope eyepiece and now I'm flocked, guided, and powered. So thank you everyone for that.

      I've written half of the write up for it last night, pt 2 to follow soon  I hope it's ok to share an external link to my personal Blog: http://milkandbourbons.tech/telescope-power
      Finally, its not in the Blog just yet, but here's the picture of the final, finished powersupply. It's a little rough looking 'cos I didn't order as much wire as I should have, but it does the job amazingly!

       
      Thanks for reading!

      I recently purchased a EQ5 mount with synscan. But rather then use the car adaptor running though a 3 pin convertor i bought a 12v 500mA DC power supply. The back of the manual states it requires 100mA (see image). So here i am thinking great this will do. Wrong. Its enough to start the hand controller and go through all the set up but it doesnt seem to move any motors. This being my first attempt i wasnt sure if i was doing something wrong. Did the brakes need releasing? - No. are the cables going to the right sockets? - Yes. After much head scratching i went back to to start and used the supplied 12v car style plus in a convertor i had. Sure enough it all worked perfectly. okay went back to my 500mA and nope nothing worked. After searching the house for a 12v 1A DC supply with the correct plug and trying that, Sure enough it all works fine. Have they simply missed a '0' off the manual or am i missing something else here? Tomorrow i'll probably go an exchange it for this 12V 1000mA Power supply. I'll let you know how i fair. And for anyone checking for power supplies (Like i did) your looking for a 5.5mm x 2.1mm power tip to for the unit.

      Hi, Does anyone know the pin outs for a Canon 1100D battery pack?
      I am trying to build an external power supply for my 1100D and have bought a cheap replacement battery that I have pulled apart, but there are four contacts across it and I am not sure which ones are the +ve and -ve terminals.
      I have taken some pictures of the regulator board that was at the top of the two batteries:

      The first picture shows the component side with the three contact pads marked B+, B- and Bc.  The B+ and B- pads were connected to the +ve terminals of the batteries and the Bc was connected to the -ve terminals of the batteries. However, when I connected these terminals up to a regulated bench power supply unit set to 10 volts DC, I was only getting a couple of volts at a couple of the contact pads (shown in the second and third photos).
      So rather than go through the regulator board, I thought I would just solder my dc/dc converter to the correct terminals to power the camera. This is where my question comes in. Which of the four contacts as shown in the last picture are the +ve and -ve terminals.
      Sorry for the waffle and thanks if you can help. 
      BTW: there are no markings on the battery case or label itself to help - cheap copy component made in China.

      Just spotted this in Avonmouth - might be interesting to someone in the area....
      A "6-in-1 Power Station with 140w invertor".
      Output 230v~, max. 140w.
      Condition: Used. Working condition unknown, not tested.

      To advanced astro_DIYers this little project will seem trivial, but it fixes something that was bugging me for ages
      My main problem was that my Skywatcher tracking mount requires a 12V DC power supply. I can use either a mains adapter or an 8xAA powerpack. The former tethers me to the house, and I don't much like running cables across the garden when there is a lot of dew. Rechargable AA cells are OKish, but only give a few hours worth of charge. Non-rechargables work better but cost a fortune.
      So, I went to Maplins and bought:
      a 4.2Ah sealed lead acid battery
      a connector to fit the SW mount power in socket
      a cable to connect the two
      crimp on connectors
      a charger for the lead-acid cell
      Assembly was literally: bare the wire cables and crimp on the connectors that slide onto the battery terminals, plug teh connector into the other end of the wire and plug that into the mount.
      I wasn't sure it would work - I've tried using one of those portable car jumpstarter packs before and found that the current was really variable, and that the charging process took ages. This battery gives a good constant current and charges fully in a few hours - much better than the 24h+ for bigger car battery size cells. I've done about 5 hours observing with it and it's not flat yet - I reckon I should be able to get 8h or more since the mains adapter supplies a max of 500mA. Compared to car-battery cells this unit is small (no more that a 10cm x 10cm x 10cm cube) and light (maybe 1kg?).
      I'm hoping this set up will meet my mount power supply needs - for now I am pretty happy with it.
