Portable solar system to run electric fans

I know it was mentioned in another post that the goal zero system may be overpriced but this one for $600 (just battery) can charge a laptop 3 to 5 times. I am familiar with these so it is a place to start.

This one will charge a laptop 17 times and cost $1300 but that is just for the battery

What are some similar alternatives and is hooking such systems to panels a simple matter?

  You shop in a higher end market than I as 100 amp hour battery can be had in the $75 to $100 range and a 100 watt panel with controller well under $200 and this would run several fans and lights for several years before needing to replace the battery and let me add that AMP HOURS is the measure to look for ....not how many times you can charge a laptop or electronic cigarette...

Post some links or recommend brands

This unit looks interesting. It weighs 12 pounds and sounds like it has a lot of power for its size

About 30 amp hours,if compared to a 12 volt battery, as the 120,000 mah rating is very deceptive because it is a 3.7 volt main storage cell and depends on inverters to produce usable voltages for other devices  with this you basically have 300 Watt Hours (I know that it claims 400 Watt Hours) of available power...300 watts for one hour....30 watts for 10 hours....enough to run one small (say 6 to 8 inch) fan for 10 to 20 hours or a good 20 inch fan for maybe two hours.

Fans require a fair amount of power to move quantities of air and few quality fns are designed for 12 volt battery use.


May I suggest you find the fans that you want to use for the job and work towards a power unit that will give 10 hours run time ,or more and maybe allow for a light or two ....though flashlights and portable lamps do work great also. You will have a far greater chance for success this way.
