Celestron Power Tank

Just out of curiosity, how long does (should) it take for the 12v DC Power Tank to recharge? Mine has been plugged-in for 11 hours now and the recharge light is still red. Hoping this is just normal. I'm new to using one of these.

All the best!

Just a few thoughts:

No more than about 12 hours for a well-discharged one. You can leave it plugged in and see what happens, but the Powertank is notorious for bad chargers. You are better off with a jumpstart battery from Wally-World, usually.

I use instead a pair of 92 Amp Hour AGM marine batteries. I use one to power scope, camera, and dew heaters. The other is either kept in reserve or used to power the laptop when there's no AC on the field. Since they are AGM they are sealed with pressure ports on the cells and there's no chance of leakage. And since there's no chance of evaporation, they won't dry out in my garage when the temperature gets hot. Cost with core was around $200 each.

Some astronomers see things as they are and say WOW!

What did you end up buying? Are you happy with it? I've read a lot of mixed reviews on pretty much all the offerings for 12v DC power packs. This one looks nice: Duracell 600 Watt Powerpack Pro and I also saw Xantrex XPower Powerpack 600HD Portable Power Source. Read various reviews on Amazon. The marine batteries sound great but are a bit out of my price range...
