nice, heavy, tricky switches

Lots of cool functions, but this thing is heavy. Also, if you don't turn the switch to on, your telescope will not get any power. You need to tell it when its on, off, or charging. Still, it does what it is supposed to, and has a red light built in that is quite handy for astronomy.

CelestronPower Tank 17

By

from Bellingham, WA  -  Casual/ Recreational

The battery tank 17 came fully charged up and I used it for 3 straight nights at about 4 hours a night with no problem at all with my big Celestron C11 telescope attached to my Losmandy G11. I have a NON - GO TO mount, so I can't speak about the current drains if running with high slew speeds on the device. I only draw .5 amps per hour with my scope at 12 volts. It also has an extra 12 volt cigarette lighter on it for using larger powered items like a dew shield, or a ccd camera. These two ports are rated up to 10 amps each which is really nice. I contacted Celestron and they said they can run for 16 hours usually without needing to recharge, and they recommend to charge it atleast once a month even if not using our else you will loose its charging capacity. I just love this Celestron Power Tank 17 and highly recommend the purchase of this.

Works fine

By

from Stamford, CT  -  Casual/ Recreational

I use this power tank to drive my Celestron CGEM DX mount. So far it has worked fine. It's powerful enough that I can run a portable hairdryer with it to de-dew my scope, and i've discovered that I can even recharge my mac laptop with it with an adapter, which means the laptop battery isn't the limiting factor in how long I can stay out and photograph. There are 2 cigarette lighter ports and a few other DC outputs as well, jumper cables, a radio, and 2 adjustable lights. It's really good for many things besides astronomy so I didn't feel guilty about buying it. It is a little bit heavy to keep in the car all the time if you obsess over your gas milage but the peace of mind is worth it.

No longer need extension cords

By

I no longer have to buy and stock up on batteries to run my 'scope when in the field. Worth the price and easy to use.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  1. The first 2 pics of the item are different. Which one do you get? 2. Are the jumper cables built-in?
Charles S  Hi, I have not used this Celestron Tank 17V rechargeable Power Supply that much, so my help will be limited. But here are my answers: (1) The Power Tank I have matches the first image, showing the 250 A rating. I've looked about and I think, though both images are slightly different, they are the same device. That being said, the one rated at 250 A rating (image#1) does show the car/other battery jump cables. Image 2 doesn't show the cables, so it's conceivable that image 2 might not have the 250A jumper cable rating because it is a version that doesn't not come with the jumper cables, but is simply a different version doing the same thing power supply wise. (2) Same as in one, there may be two separate versions. Just be sure if you want the 250 A jumper cables to make an emergency jump off, then be sure the sell page shows the 250A rating with cable. This might best be answered by one of the staff of Adorama. They have always answered my questions. Now having said all of that, I do have this added info you might want to consider. I did keep the power supply topped off every two to three months. During the time I was out of state for two months, when I came home and tried to recharge it, it would not accept a charge. I tired different ways, all met with failure. What I did find on the internet helped me to get the power supply fully charged again. What I found out was: (a) The front charging lights are deemed to be useless. They can show the power supply is fully charged, and it is just under fully charged. Also I found out that the AC adaptor that comes with the unit is basically about as useless as the charging lights. I ended up replacing it with the recommended battery charger, the Soneil 1206S battery charger. This charger will bypass the front charged/charging lights. You will use the lights on the charger itself. It is also a charger that you can use for charging other battery types, and it is a trickle charger, meaning you can't really over charge the b
Shopper  Does it include cables and adapters necessary to connect to Nexsar 6 SE and for charging and what is battery type?
Andrew R  This unit includes a 12v cigarette lighter type charging cable and a 110/220 vac switching adapter for charging via shore power. The manufacturer does not indicate the type of battery but I believe it's a lead/acid type.
