Running a fan? How long will I be able to run a portable 12v fan off of this battery?

How long should it take to charge this unit once it is completely drained?Unit has only been used once. Charging seesm to be taking an abnormally long time. (8 hours?)

The 3 Amp should be a good choice to run that fan. I have a Vornado 510B (which is similarly rated) and I run it between 50-75% voltage to get absolute quiet operation and it works beautifully.

If you mean a battery with a 20,000 mAh capacity and a fan with a .400 A continuous current drain, then the battery could power the fan for 20,000 mAh/400 mA = 50 Hrs

Hello, there. I took my Micro Fan to Disney World during the summer time. I used it every day, all day while waiting in lines. One battery lasted me the entire five days of vacation. It's still on the same battery (9 months later), however during the winter months I have used it seldomly.

I'm sorry for the delayed response. We are new to Amazon so have just found your question! We don't recommend solar fans as a sole means of running the system since they have limited battery storage and charging potential. After a day of clouds our tests have shown that the fan will stop running in the early morning. However, we do offer a 5 watt solar panel that can be connected to a battery. This option is actually less expensive than the solar fan and works very well. Geoff

Yes, This can be attached directly to a 12 volt battery. I would suggest running a inline fuse. There is not a power cord on the fan. There is just a little amount of wire off the bottom of the fan and you would run your own wire to make it a clean install.

You can also get a SLA battery and plug it into the 12v input jack on the back. A 12v 7ah should give plenty of runtime. That's really the only way to go for outdoor use, in my opinion. I've powered all my portables this way for years. D cells get expensive fast and rechargeable D's don't last long in powerful systems. (as little as 2 or 3 hours in one of mine)

Sure, there's a 12V outlet so if you have a separate inverter you could use it to create AC power. I have no idea how long it would last for any given application or exactly what maximum load it could handle. Since it's not designed for that, the manufacturer doesn't give provide any specs. But is it a substantial battery.

No, the fan can't run off batteries, at least not as is out of the box. The cord is about 3 feet long if I recall.

Battery power goes directly to this unit. If the fan stays on when car is off, you need a new one. This is what happenef to me.

there are better ways to do that because this unit requires a 12v. power source to operate.you could use a 12v.a.c. transformer as the power source and the off timer contacts for the fan motor.i believe this unit requires a 8 pin socket.

I don't think you could run 12 off of 1 battery but then again I'm not a electiacal expert the ones I have run off a car battery and how I have them wired I can turn them on with out the key in the ignition and they run for about 18 hours before it kills the battery I know it's 18 from experience

I would suspect that you could connect to a battery with a converter. Have not done that. There are solar fans that would not require electric power of any kind. We used this for one summer, took it to a desert location, planning to get a solar fan for it soon.

Yes it will run off any 12v system with a small battery you wont have as much run time as you would a deep cycle or automotive battery , but I am sure it would last all weekend if thats the only thing running off of it ... run a in line fuse of the red wire " positive " & run it how you would like from there .mine has wire coming off the fuse link so I put a eye style connector of that to the battery post .

I will charge mine and find out. I would say a few hours best guess. The fans don't seem very demanding but I'll let you know.

The internal fan is very quite but not up to the task of high loads (20+ amps) for long periods. I hooked a 120mm 12v computer fan up to the terminals and just place it on top of the unit with the fan pulling air through the power supply and out the fan. I can touch the rear heat sink now when I have heavy loads, before it was way to hot. 12 volt computer fans can handle voltage from 6-15v just fine. Just a tip.

Hi Liz, Our fans do not run on batteries. They can run off of solar power or DC power. Please let me know if you need any further information.Thank you,Nextek Power Systems
