The rated DC supply voltage for a USB connection is 5 volts, which means any 6-volt lantern battery is enough to charge cell phones or run small fans and such that have a USB connector. Of course you'll need to rig up your connections to the battery. Since USB receptacles made to plug into a cigarette lighter are so cheap these days, I used a cigarette lighter receptacle with two battery clips that I had collecting dust as a way to connect a USB charger to a 6-volt battery.

While this has very limited applications no doubt, there may be cases where a 6-volt battery used in feeders and such might be the most easily accessible power source.

Got to say that’s really useful information. I absolutely will build one. That’ll sure impress the DA teenagers and so-called techno geeks (SiL).

Speaking of those 6V lantern batteries, wired parallel(++,- -)2 of them will even power one of those “power wheels” type vehicles for about an hour. Wire 2 up in series(+-+-) and you have enough to power small 12V items.

My daughter and I made one from two feeder batteries a cigar box, 12 volt receptacle and a solar panel. It worked and she got an A. I’ll look for a picture of it.

You can also use a 6 volt solar panel and charge your cell phone with it.


lf the saying "Liar, Liar your pants on fire" were true
Mainstream news might be fun to watch

Interesting, thanks for sharing.

I have a new 6v solar panel but have converted all feeders to 12V... i know what im going to do with it now lol.



As a side question, if 6v is right to charge it then do the ones you plug into a cigarette lighter in a truck(12 v) have some kind of limiter in them?

Without additional components added to them, solar panels work more as current sources, meaning they're designed to push a small amount of current into a battery. You might think of the battery in your phone as being a small can of compressed air, and the charger as a small compressor that adds air to replace what runs out of it to power the device. Small solar panels like those used with feeder batteries are also current sources rather than voltage sources, which is why the motor on your feeder doesn't turn if you were to connect it to one. It takes the voltage or pressure of a battery to make it run.

This also explains why the 12-volt supply from your car doesn't blow up your cell phone when you charge it, even though the phone's battery voltage is usually much lower (3.7 to 4.2 volts). You can think of the 12-volt car battery as just a larger tank of compressed air. While there might be a larger supply of air, it's still pushing a small stream into your cell phone battery. However, because it has 12-volts of pressure behind it, it charges your phone faster than if you used a 6-volt lantern battery. It can also charge faster than a USB charger that plugs into a wall because these convert AC power to typically 5-volts of DC pressure to create the small current stream. In fact, you may have noticed how your phone charges more quickly while on your way to your lease than it does when pulled into your charger at home. Once the battery is fully charged, the charger is designed to stop pushing current into it.

Here's something else to consider. I have a cap light that has a re-chargeable battery in it and it came with a cord for connecting to a USB charger. Don't have a clue what size battery it has in it but it re-charges from all the usual sources.
