I use the c800 for my Tronyx Crux 1 3d printer, able to run at 100% battery for 4 hours print time + 30 minutes of pre-heat the bed before print & 5 minutes of pre-heat the nozzle at the last 5 minutes of the 30 minutes + cool down after print during the night. So after that the battery life is low at 10-20%.

Took about 6-8 hours of battery recharge to 100% from 12% with a 200 watt solar panel.

From morning to night, I used the 200 watt solar panel with the generator at 100% to do a 12-14 hour 3d print a mid size model. If your battery is at 100%, it will stay in 100-90% spot with solar panels positioned facing south at 35° angle getting a reading of 55(at 6:30)-180 watts(after 7am) until sunset.

Tronyx Cruz 1 3d printer printing facts:
Polymax Petg
240°c Nozzle temp (preheat & during)
80°c bed temp (preheat & during print)

I also uploaded the 3d printer’s specs which you can find the power info in the "power source" section.

Works well and seems to be very substantially built. The charging cables are a challenge to fit them in the top storage compartment. The only problem is the solar charging cable was missing.

They indicated that they do it in 7 business days, but it was many more days, I received adequate support but it took much longer than indicated.

Great product really help with the power surges we been having really help keep my devices running while the power was out

For $399, you can’t beat the power and convenience this thing brings. We have two freestanding wood sheds on our property that needed some electrical, so we decided to pair two 100W solar panels on each shed and run them to one of these each. Boom. A few cables later and we now have enough power to run our laptop, desk lamp, charge devices, and more during hours where the panels are pulling even 50% wattage and then have sufficient power to work for hours after it’s dark out. The app is brilliant and was one of the main reasons why I was interested in this brand. I have constant awareness of capacity/use and it doubles as a way to turn my lights on and off. Big risk buying two - and so far, it’s paid off!
