How long does it actually take to solar charge it? Can it charge any laptop eg HP?

I have only let it charge with indirect solar when i'm away for the day and its fully Charged. It will run a computer for hours I have never run out of power. Love it.

I'm not going to lie you I have never even got mine to solar charge 25% of the internal battery that it has. Could get the LED lights to move from 75% to 100% in a whole day in the sun that was 10 hours. And it doesn't even charge my Dell laptop just runs off of it when u have it ONLY in power saving mode.

PS. I have never run the charger completly down or even beyond 60% on hours of use. Enjoy itHector

Solar charging it is actually useless. It's more of a high capacity portable battery charger. I read 60 hours via solar energy to recharge. Don't know if it's true. It also depends where you are. Here in IL. it's cloudy - not much powerful sun light whereas AZ. does have scorching sun light. There is a new one that says it does it in 12hrs via solar light. "YcPower Mp-s23000 II Solar Charger 23000mah" This one says 12 hours recharge via solar energy. I use the XTPower MP-S2300 to recharge my GoPro Hero2 HD Camera (Just got Hero3 Black Edition) & Hero2 it can recharge 16 batteries. My ASUS Netbook I use it for too.

The charge was actually pretty good. it could charge your laptop, but probably only once. the problem i had with it was it turned out to be really fragile. I wasnt rough with it at all but somehow the port that everything charged from shifted and would no longer work.. so i returned it.

You can charge it via this port. It will take about an hour, but this is better since the solar panel will take forever to store a charge. The blue light indicates it is storing a charge.

This can be CHARGED by a laptop or a computer but I don't think it's powerful enough to charge a laptop. It can charge a Nokia Lumia 928 no problem, even an iPad!

This is not designed to charge anything that big. It would take 48 hours of full sunlight (4~5 days in the sun) to get a full charge and that's with it completely shut down. This works best for lower powered devices such as hand held GPS units that use x2 AA, small mp3 players, older cell phones (not a smart phone or anything with a large backlit display).

Yes, it can charge your device while being usb charged,But it can't be charged by solar power. It can charge 60%~70% power for your phone after it solar charged for 6~7 hours under normal sunlight. Solar charging is useful for emergency when outside,but do not over count on this feature, And it's not suggested that putting it in temperatures as hot as 150F,thanks your question.

Solar panels are like generators, not batteries. The panels have dual usb output connectors. You can charge an external battery that has usb or microusb input with the proper cables. Expect to get about 1.2-2.0 amps of charge rate with direct sunlight and a favorable angle (if the sun is low in the sky you will lose charge efficiency) two items will charge at a lesser rate. An Anker® 2nd Gen Astro3 12000mAh (4A Output) Portable Charger will charge at roughly 1.3 amps by itself. That will get 20-25% charge capacity of that external unit every 90-120 minutes of quality sunlight.

No it will not charge a laptop as laptops take 45-90 watts and it is limited to 10 watts. It can charge all cell phones, and most other portable devices. It can charge tablets but they are hard work. the power box pedal generator is a better device for tablets and you could power a laptop with it by charging and external battery first. The videos on our website show how to do this as well as under support, advanced power box guide.

Well if you want it to take an INSANELY long time, at about .... what's the spec for USB? 2.5 watts? yeah that would take way way way too long, probably 7 or more days, 24 hours plugged in. You can go get a 28 watt solar panel ( I learned very recently that if you multiply volts and amps, you get watts, so that's cool) I think this thing takes about 30 watts to charge at it's rated speed, so 2 or 3 watts below that won't hurt anything unless it's like a really critical situation and this is desperately needed to be charged in that situation, in which case it should have already been charged prior to this situation!

Hi, I use different chargers and cables connected to pc's and laptop,s, as I understand it just changes the time it gets to charge the device but you can use it.

Hi Sharon, this unit has a standard HP Laptop battery that connects to the bottom of the unit. It must be installed and connected to the laptop for the laptop to work. There is an HP AC power adapter that connects to the wall outlet. The adapter charges the battery and also powers the laptop when the battery is fully charged. Not sure how long the unit will operate on battery alone as I have not tried yet. Typically you'll get about 2 hours of battery time before it needs to be recharged.

Unless the Laptop chargers via a USB Port, then I don't believe so. The solar charger has a USB out which delivers 5 volts DC. Most Laptops have a transformer connected to a cord which requires 120 volts AC. I would also assume that the laptop battery itself probably would require at least 12 volts DC or more if it could be charged directly. You could get a regular solar panel to do it if it was connected to a 120 volt AC inverter.

I get only about 12-17% charge to my phone per each charge of this solar device. The solar device takes about 20 hours to charge in the sun

Use a 2.1 amp charger with a micro usb plug for the device. It will take several hours to charge. If you use a 1 amp charger it will take at least 6 hours. I doubt that a usb slot on your computer (most are about 0.5 amp) would work.

I've seen some discussions where there was a regulator required for use with solar chargers in some situations. Had the same issue with my lawn tractor; no charge after 8 hours in the sun. But it works fine for other batteries... go figure. May want to ask someone at your cycle shop about how to use this. And the other responders are right, if your battery is stone dead this thing isn't gonna help you. I found a 6A Stanley charger at Lowe's for $25 to use on the lawn tractor.

I do not know, i've used it for charging batteries, my cell phone, my ipod, and my tablet, but i've not tried my laptop yet.

Laptop only as far as I can tell. But you may be able to get a usb outlet at Radio Shack. It stays charged pretty long.

So far I have only charged off a USB port, works fine, in 8-12 hours. The claim is that the solar cells will charge in about 4 hours, but have not yet had occasion to try it out, the savings of electricity in the city probably not worth the wear and tear, e.g. peeling off the plastic!
