Schumacher XP2260 6-in-1 Jump Starter to power mounts and other astro stuff
I have been using these smaller power packs that I have collected, using them to run the Losmandy mount with good success...
Light, I carry two for Chicago Astronomer Star Parties. I have also been using them to power the new CG-5 mount, but the go-tos are energy hogs and I can get about three hours (or less), on a full charge. It comes to a point that the energy drain is enough that the CG-5's computer just won't calculate anything and will displays error messages on the hand controller readout.
I need something more robust and versatile.
There is the usual solid stand-by of the Celestron Power pack...
This version even comes with jumper cables!
C.A. Patrick has a similar one and is happy with it's performance. I almost pulled the trigger several times for the same unit, but for one reason or the other did not. About a month ago, my car battery died and I needed a jump. A co-worker said he would give me jump, but would use this to do it with...
Hooked up the cables and with a single turn of the key...started the van with a completely drained battery. I was impressed...

Looking over the powerpack, I saw that it was more than just a jumper box, but also had several other options that could be of use out in the astro field...
It has two 12v cigarette power outlets and 2 AC outlets and a USB port - which are the items that caught my attention - apart from the jumper cable abilities. It also has the inflator/deflator pump and a 3 lamp LED light, but I don't see using those often.
So...I ordered it and it arrived in about a week...
It's hefty, weighing in at 26 lbs, but so far, in limited usage...works ok. Runs the Losmandy and CG-5 very well. I like the digital display of volts and watts, as the ability to use AC power in the field is very attractive. Reviews state that some are getting about four/five hours of television hooked up to one of these. Could prove useful during a black out as well for astro intents.
Let's see how well it performs in actual field use.
