"Rechargeable solar panel or kinetic crank energy"
1359724
solar panel with D-Cell back-up. You can select power from the solar batteries or the D-cell, gives it added flexibility for use in emergencies

Well worth getting, is the most effective and efficient solar panel/light, I've seen

Rechargeable solar panel that folds out for charging and folds back flush with the unit. It is a marvelous lantern and works many hours on a single charge.

Rechargeable solar panel and battery operated too. I bought it after Hurricane Sandy and we lost power for 6 days. We used it during the past winter storms in the Northeast when we lost power. Worked very well! It's a perfect size and both the light and solar panel flip up and then fold back down flush.

That would not work. It would be like trying to heat your home with a candle. The sun has incomparable amounts of light energy compared to anyman made light. For example say a 12v 7ah battery takes a day to charge in the sun. It would take the same battery 2 months to charge with the lights in your garage.

The solar panel is the only way for it to work. The solar panel is the only way to charge the batteries. You plug it in and leave it alone.

I actually use mine with a voltaic solar charger while biking. I find it charges faster than the computer and is free when it is very sunny. However, it could also depend upon the batteries. The batteries that came with it didn't last long, so now use the rechargeable energizers. The heat from the sun may have sped up the degradation of the original batteries, too. Love the recharger and gave a couple as gifts.

This unit generates a regulated 5V at its USB port. It has no idea what type of appliance you connect to it. It is up to your appliance (cell phone or tablet) to monitor its own internal battery status, and stop charging once its internal battery is full.The solar panel on this unit works, but very slowly. It is best to fully recharge its internal battery using an AC-to-USB adapter, then rely on the solar panel only as a trickle charge.

Yes, I use a large panel at home and it can fully charge the batteries in about two hours in direct sunlight. I have a small 40watt panel that I used out in the field and it kept my ham radio running all day without a decrease in stored battery power.

The manufacturer- "windynation" recommends one- "100 watt solar panel" for charging batteries of 50 ah. Example-If you had two 25 ah batteries connected that would be 50 ah. Now depending on a lot of variables I could get by with this for awhile; and someone else may not.My train of thought centers on it is better to have it and not use it than to need it and not have it. But if you don't need it for extended periods,have plenty of sunshine,and can keep the little woman away from the blow dryer you may be o.k.. I am not an expert though. The best info is sometimes available from the literature,the mfg.,etc. and you can always contact them.

no problem with my crank but i've seldom used it...mostly used solar. batteries can be recharged but seem not to be normal size or shape, hard to find replacement for them when they died...multiple battery only shops didn't have. overall i found the unit far too complex for a "survival" and "emergency" type radio. my belief is that you want ruggedness and easy to use basic functions not lots of complex options. better and simpler options available.

Make sure that you ask for solar rechargables. Apparently there is a difference!

Honestly, I don't remember. I think I purchased cables but can't remember for sure. If you contact the seller or manufacturer I'm sure they can tell you. On another note, this is a good piece of equipment. I have it installed on my SunTracker Barge and it works perfectly. I always have power to crank. Also, if you are like me and your family spends hours anchored, swimming and listening to music, I recommend a small solar panel. It will trickle charge all day in the sun and keep your batteries topped off. Hope this helps.

I believe any rechargeable battery can be used in a solar light application.

The solar battery can be charged via USB. If you have a USB phone charger that plugs into the wall it should work for this too. You can also charge it using a USB port on your computer. You can use any of the USB cords it comes with. Its really much more versatile than what the instructions show.

If I had it to do all over again I would probably buy something better. Batt is probably 1600 and the solar panel puts out 1.5 watts per hour. Took 2 weeks for solar panel to charge internal batt in the window sill, direct sunlight in summertime.

These solar panels are the best. They are a little heavy though. My experience with these panels to have a very good experience is to plug them into a 30 Amp Solar Controller into the input side. On the Output Side of the Battery Charger going outside the controller plug in this device first, Lanzar VCAP5000 Vector 50 Farad, 16 Volt Hybrid Capacitor on the input side of the capacitor. On the output of the capacitor, is the side to charge the battery cells. The logic for this is that the capacitor hybrid cell is storage for the solar cells because the prediction of cloud positions are random and hard to predict on any given day. Thanks, Dr. Sheldon Cooper.

The battery is where the energy is stored. The solar panel recharges the battery. No, a battery is necessary to hold the charge.

I would not, its designed to have electricity running through it all the time. The battery tender turns on when the battery needs juice. A solar panel is not constantly pulling energy, and this is always turned on. I would ask someone who is an automotive electrician.

This is a very nice solar panel that is mounted on a somewhat flexible metal sheet. I produces about 16v dc at the contacts in Florida sun (rated at 12v for a 12v battery), but I use a solar controller so it won't overcharge my battery. I have it hooked to a 12v trolling motor deep cycle battery on a small boat. I have not had to externally charge the battery since attaching the solar panel, and that gives me a few hours per week of power.
