    Default Power Tank or DIY Portable Power Solution!



    I've been trying to decipher portable power solutions from various threads and am now very confused. My question is what would be wrong with Orion's 17ah power tank? It may be pricey at $140 US, and it may have somewhat useless gadgets, and it needs constant trickle charging or death, is that it? The reviews seem to unfavor Celestron tank offerings, and the bad Orion reviews seem to indicate user error resulting in beyond dead units.

    What I like about the power tank is it has regulated 6V and other onboard receptacles so it is very versatile. I am intrigued with forum member Bob327's power scooter battery performance record. Do power tanks fail or have short life even if maintained? Are there any good links on a DIY power solution for dummies?

    I would like to be able to power not only 12V drive motors, but also various accesories that are 6V and/or 9V. I'm not an electrician, and I am concerned with frying expensive accessories.


    I currently need 12V to power a CCD Camera and 6V for a dual axis motor drive. The CCD camera warns not to dare go above 12V or the unit will fry. So I'm a little leary of unregulated components, or shouldn't I be?


    Thanks,

    I would think that it would be cheaper to build your own but that is usually the case. That is the main reason that it is more expensive because it is pre made. And beings you aren't electically inclined it would be the best bet. I'm sure that the DIY people will be along shortly to tell you and give you advice on how to make your own if you want to go down that road. Good luck

    Not sure why, but the Celestron Powertank seems to have fried a lot of electronics in its time. Not at all sure why. . .

    Part of my question would be how much you want to spend on power. Also, will you be needing to transport very much?

    If you already have a large deep cycle battery around that might be an option for use.

    There are a lot of options available. Must of us end up using relatively inexpensive jump starters.

    I agree, the jump starter is a good way to go, not expensive.. Mine has been a good server now for almost 5years so has earned its keep... Also a battery will , in my opinion, give you the cleanest DC volts available. I also have a well regulated AC/DC power supply but I'm always concerned about component failure and where the voltage will end up.. Best to play it safe with the jump starter.
    cheers.

    I bought a Peak jump starter power pack. I also had to buy a cord to use from the cigarette lighter recepticle (it has two) to the base of my Celestron 8i. It works great, and it was only $35 on sale. I even used it to jump start a car already, it did great there, too. It also has an inverter to power 120 vac. So far I'm sold on it. I can't even tell it has used any of its power after several hours of use, unlike the short life AA batteries.

    I picked up a Diehard 750 jumpstarter pack to use as a power source for my scope mount two years ago from a Sears Essentials that was going out of business. Payed $20 for it I think on clearance. They are on KMart.com for $65 right now. Works pretty good and the battery is a standard size used in UPS systems so if it ever goes bad its easily replaceable. It is only 12Ah but I've never drained it to even 3/4 after a couple hours use with my 6SE so it works well.

    As a car starter you have to let it trickle charge your battery for several minutes before it will jump start things, but that's still easier than finding someone willling to help out at 2am.

    Thanks Bob. I'm going to take a look at that battery Pack.

    This looks like a project I could handle, although the step down unit on ebay is sold. Is there another place to find step down converters? Is there a difference between a charger and a trickle charger? If I go the scooter battery route, what would be best to maintain (charge/keep charged) the battery? Is there a divice that also has the de-sulfer component? It would also be nice to have a guage that would indicate the ready to use charge in the battery, are those available somewhere?

    Thanks!

    orion's is pricey- but most orion stuff is anyway, jump starter is the way to go- not sure what you need adaptors for, most stuff is 12v, but $60 for that is ridiculous- i think i got mine for $2 or $3 with multiple V settings on it
