can you charge the internal battery with the solar panal?

Yes, but not fast or complete. If you got no charging source, though, it works.

not very much. the solar charge will not take it from 0 to 100%. think of it only as a very minor extra tool. unfortunately you can not count on the solar panel. I have tried it on a boat trip with clear sky, full sun, left it on the deck for the whole day and the maximum I could get was not even around 20% of charging.

Yes, and the brighter the sunlight, the better the re-charging goes; so I pay attention to align it to direct sunlight as much as possible. Had the unit for quite a while now and still going strong.

Yes. The solar panel charges at a low rate. I do not have my paperwork with me, but I believe it charges enough to then charge a cell phone 1 or 1.5 times after a 7 hours with direct sunlight solar panel to internal battery charge.David B.Electronic Technician

The solar charge rate is very slow. Depending on bright sunlight and several days I guess you could.

You wouldn't need to charge this as it is a charger. Whatever you could charge with a solar charger you could charge with this provided the connections are compatible.

Yes, this panal has the capacity to charge your batteries, just remember, the 20w is at optimal environmental conditions, sun, angle positioned ect...I always connect in parallel. You didn't mentioned the 'what' you are utilizing the batteries for...heavy watts out, need more watts in. Good luck!

I'm sure you can let the sun charge it but I charged mine overnight because it gave it a full charge to start. It won't charge at night or cloudy days so best to start with a full charge.

Yes, Connect the positive lead of the solar charger to the positive terminal of one of the batteries and the negative lead to a negative terminal.

I don't think the solar batteries can be recharged that way but I'm not sure.Maybe contact the battery company and ask them.

yes... the solar panel doesn't charge it all the way up. The best way to "top it off" is to plug it in to a car phone charger or something simialar to that. A tablet charger works the best.

Yes, just connect it independently to the batteries(not through the solar charge controller).

I don't know about that one. I've always hooked up the 12V battery directly to the solar charger. A lighter adapter didn't come with the solar panel.

The inverter is designed and supported to be connected to a 12 volt battery. You can use the solar panel to recharge the battery while the inverter is in use.

Yes! it has dual charging options, it can be charged via the included solar panel and via any wall outlet.

Spare batteries or you could use something like this: Opteka BP-SC6000 Ultra High Capacity (6000mAh) Backup Battery Solar Charger with Faster Charging EcoPanel

I charge mine with the Anker 14watt solar panel. You can also charge it using a usb cord. Just connect it to a computer or any other usb port that has the ability to charge. Great battery.

Sure, I plug it into a 12v back up battery I charge with a solar panel. But you could use an outlet.
2204257
No. You can plug into a wall usb or othe panels as long as it has appropriate connectors and you can also use other brands of rechargeable batteries.

i have 28W solarpanel which produces voltage between 15 and 21V depending on sunlight. Can this battery be charged with variable Dc Volt from the solar panel? will it damage battery ?

It has internal battery that can be charged manually by the crank, solar, or by electricity. It needs an ac adapter that is not supplied but easily available. The internal battery cannot be removed as far as I can tell.
