Do you need a solar panel to recharge?

No but the top/ "solar panel" is entirely inadequate in my opinion. 8 hours in direct sunlight to charge 2 AA batteries doesn't meet my needs.

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.

You always need a Solar Charge Controller between the solar panel and the battery. This particular solar panel comes with a solar charge controller, so you don't need to buy one. You will need to connect it. The controller that came with the panel I bought is not high quality. I purchased a separate charge controller. The charge controller needs to be rated for 12 V battery and at least 2 A (amps). There are many available. How you connect to the battery depends on the battery terminals. I need reliability, so I bought ring crimp-connectors that fit the clamps on the battery.

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.

All solar panels should use charge controllers. For this controller you need at least a 5-10 amp controller to support this panel.Let us know if you need any further help.Regards,AW

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.

Yes. You just need to ensure that you have a cable to connect from the USB port on the solar panel to your device.

Yes it is fine. Most solar panels have or need a charge controller because they put out 24v. This panel has an integrated controller, and will automatically adjust to a 12v (or 24v) battery system.

No, it comes with batteries, and the solar panel keeps it charged up. You should not have to get batteries for it for a very long time.

No you don't need rechargeable batteries. There is a built in battery inside that is rechargeable by solar. Great light tho.

if the item you are replacing the battery in is "solar powered" they use the sun to recharge in the item you put them in - i have them in solar lighting out back and they recharge in the item using the sun and the "solar panel" in the item. You cannot charge these in an item that does not have a solar panel on it though. So using them for some regular item, you would need to buy a charger to recharge them

All solar panels are only able to charge batteries. You need a dc to ac inverter and battery to power an appliance.

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

I need to amend my previous answer. It DOES have what appears to be a ac outlet in the back, although it doesn't ship with a charger. But the solar panel works fine and I don't see the need for charging.

NO. This solar panel is designed to keep a deep cell battery fully charged. The dc battery drives the electrical motor.

No batteries needed. The kit uses green energy so the rechargeable battery that's included is recharged using an included solar panel.

No. You also need a voltage regulator to ensure no overcharging of your battery, or you need to manually monitor charging so you do not ruin your battery. I think the regulator I bought was less than ten dollars and it was all I needed for three panels.
