Solar Panel Product

The unit is compact and a little heavier than I expected. The two carabiners also snap the folding panels shut. The white light is very bright with steady on, flash, and strobe. There are 4 blue lights to indicate charge level and charging. It appears lights 1 through 4 represent battery charge level. There is a 5th "hole" in the case (would be position 0) but there doesn't appear to be a light in that location. On arrival, there were 3 lights of charge level. When initially charging on USB, the 4th light was still blinking after more than 12 hours of charging. The lights are a little difficult to see as they are not very bright.I then charged my S10 phone using a USB cable. The phone’s battery level was at 86% and fully charged in 31 minutes, about the same speed as my wireless AC charger. I then placed the unit in bright Arizona sunlight for about 5 hours. It was very warm when I retrieved it but not as hot as I expected (outside temperature was just over 100 degrees in the shade). The battery charge level showed 4 blue lights. I put it back on USB charging and it shows 4 blue lights. This should indicate the battery is fully charged. The case is leather or artificial leather. My phone is in an Otterbox Commuter case and it charges wirelessly with the case on,.The unit indicates it is 8000 mAh rather than the 6500 listed. The USB outputs are labeled 2.1A. The input charge port is micro USB (not type C).I also returned the first one I ordered because the battery level 4th light was still blinking after USB initial charging all night. The second unit behaves the same way. I don't know of any way to test the true battery capacity.I charged my S10 wirelessly again when the battery was at about 86%. There were 3 blue lights for battery level after charging. I placed it back on USB charging. The 4th light blinked and was still blinking 3 ½ hours later. When the USB charging cable was removed and the battery level checked, it showed four solid blue lights. As soon as the USB charging cable was inserted, the 4th blue light started blinking again.I rate this as 4.75 stars presuming the four blue lights indicate full charge level and the even though fully charged, the blinking 4th light represents USB charging.

What I saw in the leading sellers was that they wished a device had a battery pack. Well, this one does. It stays charged and it charges quickly on a dashboard or tree or rocks. We plugged in two devices and didn't time it but by the end of the afternoon, our devices and the battery were all charged. We love not having to turn on our generator and this is a great device to charge phones and headlamps. Don't keep phones plugged in past their charging time, though. When not in the sun, it'll drain the batter with already charged phones still plugged in. We love it. Solid and dependable product for our uses.

Love everything about this, except the mini USB . Love the size, the solar panels, the magnet and hooks, and the wireless charging capability. These things all work well AND it's water proof for the backcountry. The connection to recharge it from a wall socket is a mini USB. If this was a USB C I would give it 5 stars. Wish the developers would've upgraded this bu now, but if you can look past it this is a great little setup.

This really works… it’s an amazing piece of equipment

As an avid backpacker and mountaineer, I was really excited to use this solar battery on the trail so that I would have some way of keeping my phone just charged enough to be able to send an emergency text if necessary. I was super excited because some of my mountaineering buddies had solar charged power banks that they LOVED that looked at least from the outside like this one.Well, this one DOES NOT WORK! I've used it on multiple trails, and every time it has failed. It will barely charge my phone once before needed to be recharged, and even after a full day strapped to the outside of my backpack on a bright sunny day, no dice. It hasn't charged at all. I've had to cut one trip short because of this, and detour on several others to places where I could recharge this. Unsure if I just had a bad pack, but this Survival Frog ain't surviving

UPDATE: Frog replaced my defective unit promptly and with no questions. Very helpful. I would be happy to deal with this seller again.At 12 months and 3 weeks, the battery in this device has begun to swell and push the solar cell located above it out of the case. It is nearly impossible to snap the case shut. At this time I am growing concerned about the possibility of a fire. Otherwise, I have been pleased with this item.

I got this for my husband for Christmas and he loves it! Charges up fast and extea battery pack is a plus. He likes taking it with him on hunting tripsHighly recommend this product and seller

When the sun and full charge did not work for me on my first unit, I returned it and tried a second one. i deep charged and it took a better charge. The problem with the sun charge is i live in Cleveland Ohio. and it has a lot of overcast days and not enough sun even on bright sunny days to keep it in the sun and let the blue light show it is on charge and yet it never fully charged even after two sunny days in Cleveland Ohio. it may work in a better location. when deep cycled twice I could only get one charge to my Galaxy S-24 ultra cellphone. the unit would only charge the cellphone 75% to 100% according to how low it was when I put on the charger. Note: even if charged 75% to 100% it would not the ability to charge it a second time. I returned the unit. it may work for someone else but not for me. I tried two of them.
