Good solid item but really heavy, so be aware of that. If I could have afforded the Li version, then that would have been better. That said, I have used it once, and provided a good steady flow of power to my slt mount and dew heater, whilst the in built radio kept me amused (nice little bonus). Good for the price, just the weight to be cautious of. Really speedy delivery from FLO, so really happy about that. Thanks everyone.
Thanks FLO for answering my queries on portable power supply and also the recommendation on this. Good choice. Ordered on a Tuesday and it arrived on a Thursday to the very North East of Scotland. The Celestron Lithium PowerTank may have been my first choice originally but this solution was half the price which allowed me to purchase a few other items with my pocket money. I have only had this two weeks and only managed five nights out with it but so far no issues. It lasts the whole session on my CGX with my SW200PDS on it and that is all I can ask for (maximum session duration was 3.5hrs). During the session I also use the red light to view my notes and night plan (possibly this will be a little too bright when the moon disappears from the later evening skies here) and I use the white light at the very end on the session as I leave my field to check I have not dropped anything, this works well. Not used the radio, however, tested and worked ok. Comes with a car socket charger (which I have not used as yet) and mains adapter which plugs into the side. Not sure how often you should charge, however, I have charged after every session but when I have used it for firmware updates or trying out something with the mount for half an hour or so I just do the next session on that charge too. For anyone's information, there are two connectors on the back that allows you to 'jump' your car, however, this is not the case of jumping directly from it. You are suppose to put the PowerTank cell onto your flat battery for half an hour, remove it, then start your car, it gives your flat battery a boost. I wondered how this was done before I bought it but it is clear in the instructions. Don't anticipate using that feature but thought it might be helpful if you are considering buying one to explain. Anyway, five stars for this product, highly recommended for portable field power supply. I highly recommend buying this from FLO too, great team to work with and super fast delivery too.
Got this instead of the usual car jump pack to power my portable set up,, I'm going to be powering a lattepanda with it, having to slightly adapt it to get higher amp usb socket,, hopefully the manufacturer can look into upgrading the USB ports to higher amps at some stage,, but it seems a cracking bit of kit so far,, and I'm happy I bought it, davy,, video astronomy forum
