How many minutes/hours does it take the solar panels to charge the external battery?

The external battery holds a charge for a long, long time, therefore I haven't seen the need to charge it up. I have charged my I phone 4 with it. At 45% full the solar panels charged it in less than an hour. The panels work very well and the size is right and the price is right. From what I understand, you can encase it in a ziplock bag and it will work just as well and keep the panels protected.

it depends on how much sunlight you have available. In direct sunlight, with only the battery plugged in, it's on the order of 4 hours for a full charge of the provided LiIon battery, give or take. In practice, I've always had one battery topping up and a phone in the other slot, neither fully drained, so it's hard to answer precisely. When I'm camping but not moving campsites every day, this solar panel means i don't worry about running out of charge for my phones, as long as i use them conservatively.

Approximately 6 hours in direct, full sunlight. Try to keep the panels at the proper angle by adjusting panels in relationship to the sun for maximum charging of the battery.

The panel, horizontal in mostly direct sun, in January, in Clemson, SC charged the external battery in around 20 hours. Keep in mind this is winter sun, and through a window.

It usually takes around five to ten hours depending on the device that you are trying to charge.

I normally charge it overnight, but if I had to guess, it's about 3-5 hours. However, the length of it being able to charge other things far surpasses three hours.

The battery can be removed from the bicycle and charged without being attached to the bike. It can take from 4 to 8 hours to fully charge the battery, the incremental progress is not known or has yet to be determined. I hook my battery up to the charger every other night for about 6 hours; owners manual says you should never charge it longer than 18 hours continuously.

You can charge this Power Bank from any USB port, either from your computer or AC adapter. If the USB port is only rated 1A, the power bank takes more than 10 hours to charge. If the port is rated 2A, it takes around 7-8 hours.

Although I never timmed the charging of the Battery, I do know it doen't take all night. I would guess about 5 or 6 hours

I haven't actually timed it but I guess it takes between 2 to 3 hours. It depends on if you are using it while charging.

You charge the camera, not just the battery, by attaching the USB cord to the camera at one end and the USB-AC Adapter at the other and then plugging the whole setup into the wall outlet. It can take up to 4 hours to charge. You can also charge it the same way through your computer but it can take much longer. The battery is wafer thin and tiny. Because it is so small it doesn't allow as many shots as say a DSLR battery or a larger compact camera. So I have purchased a backup battery at Amazon so I always have one with a full charge ready to shoot.

I'll guess a few hours, if you use it a lot. I keep mine sitting in the charger all the time, though.

8 to 10 hours. Did not charge on the solar panel at all. Two different units they shipped me. Terrible product. Carried it 500 miles on the Camino de Santiago for nothing.

Depends on the strength of the charging supply. A couple hours. I do them overnight.

Not by more than a few minutes. Would take three or four full days of sun to charge your battery, and thats when your not using it.

You'll need a 24V solar charge controller, hooked up to the solar panel and then to your battery. In full sun, it will take about 20 hours to fully charge a 100 AH battery. However, you should not let your battery get much less than 50 percent of capacity between charges.

Charging time will depend on several factors... how sunny it is, how much capacity (rated in Amp Hours) your battery has, etc. The R15-300 produces 0.3A (at 15V) to charge a 12V battery. For example... If your battery capacity is 10AHr (amp-hours) and it's down to 70% full, that means you need to add 3 AHr back in... As this panel produces 0.3A, that means in 10 hours of full sunlight (max sun) you will restore the depleted 3Ahr. Of course, the sun intensity isn't always at max strength, so it would actually take longer than that. If you need to recharge faster, then a larger panel will be needed. I hope this helps explain it. Pat

It's only 17 amp hours so I'd say for 500 watts, about 10 minutes? Probably less? If you want more substantial running time, your best bet is probably to build your own kit with a solar charger battery, where you can usually find 125 amp hours or more, and then get an inverter and charger separately. It'll cost a lot more but 125 amp hours from a 12v battery should power 500 watts for over an hour.

Depends on the voltage rating of your charger. I would say 4.5 hours for both.

depends. I charge mine on airplane mode and it took an hour I've also been using it as it charged as I run my own business and it took a little less than an hour and 45 minutes
