I have had this unit for a year now and have LOVED having it. The red light is very useful for being able to see without ruining your night vision or disturbing other stargazers. The spotlight is awesomely bright and has come in handy when out in very dark places. I can run my Celestron Nexstar telescope on the unit (while using the red light) for several hours.
The only problem with this unit? The wall charger sucks more than a Dyson vacuum (and Dyson's have a ton of sucking power ;-). Following the instructions I plugged the unit in to charge it before initial use, after 72 hours of being plugged in the charge was still not full. I did a quick troubleshooting search and everyone said the same thing, the wall charger is useless. We were heading out of town to a dark sky park so I didn't have time to get a different charger (many people recommend using a Battery Tender or an NOCO Genius G750 charger) so I plugged in the car power cord (it goes in your car's power terminal) and charged the battery that way on our trip, the unit was fully charged before we got to our destination. Thinking that maybe it needed the extra boost from the car to get it's initial charge up and going (and disbelieving the online reviews) from then on I only used the wall charger. The unit never said that it was at full charge but I figured if I followed the guidelines of topping off the charge every month, charging before use, and charging after use that everything would be ok. Enter 4 days ago when I went to charge the unit for use and it wouldn't charge, again 72 hours of being plugged in and the "needs charging" light was still on. Again I had to take it in my car with me and charge the unit up, worrying that after a year of never being charged up I had completely killed the battery, thankfully it charged just fine in the car. I have now purchased the NOCO charger (as it had the most recommendations on forums) and will never again use the wall charger that came with the unit.
It is only 7 amp hours. This might seem like a lot, but it isn't if you have a medium-to-large scope and mount and need to run dew heaters. This can easily burn through in less than a night. For close to the same money you can get yourself a rechargeable deep cycle marine battery and battery box with built in aux. plugs and power meter. This will give you 25-35 amp hours. I ended up having to do this in the end.
I almost never use the flashlight - actually never. My small red pen flashlight or my head mounted one is used almost exclusively when in the field or in the back-yard.
The USB ports may come in handy for people, but I make sure my devices are charged when I go out, so have never needed them. Like I said, if you have a decent sized scope running heaters or lots of accessories this won't be enough for you. Go the marine battery route and have no power worries.

This same model is also available with other branding and equally without which the latter reduces the price considerably... but beware the bonus car charge function. Some insulation tape will do but when connecting cables you will forget until you get a shock. Even short out the charger itself.! The next model up includes a radio but only one 12v socket so compromises are abound if you want to power the Scope controller and a dew shield... most necessary in the UK. I have also. modified the large torch with red film so setting up without losing my night vision is a thing of the past.... Overall a great buy... BUT don't kill yourself....seruously...get it professionally protected or disconnected.
But I would be lost without it
I mean trying to power my C6SE with batteries is a joke
This beast is therefore a lifesaver... but I can't help thinking smaller cheaper and prettier would be better
And such a tool is probably certainly available from Celestron...also this thing has to be charged every 6 months (or is it 3) don't quote me on that... but you'd best check and don't forget to keep charging it otherwise you'll ruin the battery. I write the date of my previous full charge (around 24 hours) so I know every 3-4 months to charge it up. Pain in the neck, but hey... that's what I have to do.
