I was looking for something to charge my phone and some batteries in case of an emergency (power outage). I wanted an inexpensive but decently powerful solar panel and this fit the bill. It is actually smaller than I expected and the quality seems very good. It works well and provides enough power to charge my cell phone or to charge my AA batteries with a small USB battery charger. As others have noted, there is a plastic film covering the panels that bubble up a bit. However, I am pretty sure this film is meant to be removed so its not really an issue. My only negative is that the price could be a bit cheaper. There are similar panels available for about $50. But overall the quality is excellent, its not too expensive, and it works like it should!
I was attracted to this model because of the 18V output port; I thought it would be great if I could charge my laptop on-the-go. I decided to test it. I positioned the panels in full sunlight on a hot day and I connected them to my laptop with one of the various adapters supplied in the box. The...
I was attracted to this model because of the 18V output port; I thought it would be great if I could charge my laptop on-the-go. I decided to test it. I positioned the panels in full sunlight on a hot day and I connected them to my laptop with one of the various adapters supplied in the box. The result? My laptop didn't even detect that anything was connected. I tested the output with a multimeter and it appears to be the correct voltage but my laptop is acting as if nothing is connected. Enthusiasm gone. This unit has a little black pocket. I already own a similar folding panel set; the pocket on this model is far smaller though this doesn't bother me 'cause I don't know who'd put their phone (or any other gadget) in these pockets anyway. Heat will severely reduce the life of the battery in your gadget. These black pockets get hot! The unit has a thin transparent film on the panels. It arrived with heaps of scratches showing. This made the unit look extremely used (perhaps it was). There are orange labels on the panels. These labels are simply stickers that are stuck on the thin transparent film covering the panels. There are 4x "Sunwalk" stickers and 3x "POWER SOLAR PANEL 3 Watt" stickers. Why not 4? What's funny is just one sticker on one panel is slightly different because it says "POWER SOLAR PANEL 3.5W" instead of 3W. Odd. Anyway, If you decide to remove the unsightly scratched clear film you'll be removing these orange stickers too since they come stuck on it; I haven't tried yet but I'm very tempted since this clear film looks terrible. Just to compare and contrast: the folding solar panel I already bought has similar labels (blue ones) but they sit under a thick protective transparent matte plastic covering the panels. The blue labels on my existing unit can't be removed & the thick protective plastic is designed to stay on the panels. On this unit, the plastic film placed on these panels bubbles up and it seems to be designed to be peeled off. This scratched transparent plastic makes my unit look awful (see pics). This is not the feeling you want when buying a new gadget. Speaking of used: my unit arrived with very visible scratches on one corner of the solar voltage controller too (the square thing next to the pocket). See pic. I guess I don't have to say how I feel about this. My existing panels (bought at a famous auction site) arrived in perfect condition suitable for gift-giving and 1) worked better under the same conditions (outputting 100mA more current) and 2) arrived with metal spring hooks for the panels and 3) cost less too. If I were to compare the fit-and-finish of this model with my 'famous auction site' model: there is simply no comparison. This one just cannot be given as a gift (not with a straight face). Improvements? The exposed voltage controller should be made out of white plastic to keep the temperature far lower; heat can't be good for electronics. The panels didn't perform as well as my existing model and the 18V output didn't work for charging my laptop. Overall I am very disappointed in this product. The only real advantage to me is that I like products with no logos on them and this product only has easy-to-remove stickers on the transparent film. It can be made totally unbranded with no useless logos or text that doesn't need to be there. Sidenote: The claimed weight of this unit is 730g. My unit weighs 771 grams (without any attachments or cables). Conclusion? Basically, my main interest in this unit was the 18V output. That didn't work for me. The unit charges the USB devices I own OK (Android 7 inch tablet & 4.5 inch phone) but it still performs worse than my existing portable 4-panel folding kit from that famous auction site. If my sample is any indication, the fit-and-finish of this unit it terrible; it looks and feels used and I am disappointed for buying it. I would not recommend this unit and I would be embarrassed to offer it as a gift. If you only want to charge USB devices this may be OK but I think there are better choices. But if you can get the 18V output working for your device then I think this unit is still worth considering.
Very compact, not to heavy for backpacking. Very good build quality, looks good and feels sturdy. Has a SINGLE USB connector, but this is rated for 2 amps, so with enough light should charge an ipad. Very cloudy day in England, but summertime (so bright light)charged my Samsung S3 with NO direct...
Very compact, not to heavy for backpacking. Very good build quality, looks good and feels sturdy. Has a SINGLE USB connector, but this is rated for 2 amps, so with enough light should charge an ipad. Very cloudy day in England, but summertime (so bright light)charged my Samsung S3 with NO direct sunlight.. The 19 volt connector can be used with a cheap voltage converter with a USB port attached, giving the user the option of 2 USB ports. The panels come covered in a thin clear protective film. I removed mine to improve performance, but if you get good sunlight, you might want to leave them on to help protect the panels. Its a solar panel, with all the usual limitations.
No instructions. Are any needed ? Handy little loops. I use snap links on mine, so when hanging off my Bergan its quick to un-hook. The little built in pocket is good for adaptors and cables, but that's really all, as its too small for most phones. The best foldable, portable with best power solar panel out there. Buy one. Remember it travels along way, so be patient for delivery. Mine from china to England took 2 weeks. But free postage is a bonus.
