It's actually more efficient to charge a battery then the phone, than to charge a phone than the battery, but not for the reason you think. Yes you lose power going from solar to battery to phone and it is 'technically' less efficient but the battery can accept higher amperage, meaning you will be able to take advantage of and capture much more sunlight as electricity initially, that the mechanical losses later are minimal in comparison
some vehicle starters have micro-USB slots - so, could I somehow hook that up to a solar panel? At least one of my phones will refuse to work if it gets too hot from sitting in the sun.
the Army gave me a six panel charger. we had night vision goggles, radios, red dot sights, gps. something always needed charging, and you wanted 100% before sundown. i had it lashed to my rucksack. it worked great when new, but as it got scratched over time it slowed down.
Please do let us know how this works with repeat usage. I am a financially particular kinda guy who appreciates purchasing 'quality' the first time. Also, I'd like to thank you for the work that you do, your videos are very informative. If you are ever in Arizona, and would like to stress - test phones with large John Deere construction equipment, let me know.
I bought one of those when I went to Greece. I believe mine was made by a different company though, maybe it was Anker.. Anyways, it worked really well for me. It did take some time to charge but it still worked!!
Excellent. Those of us living on the road can really use products like this. I boondock frequently so I'll have plenty of opportunities to use it. Thanks for the review. I'll let you know how it works out! Have a great time on your trip.
Interesting, whether it will loose the efficiency if you will put this charger on the winowsill (so there will be a glass between solar panel and sun) or not?
I'm a bare bones, broke back mountain, back country camper and the issue I have with solor panels is simple. They only work with sun. SO, my suggestion is to pair it with a battery bank (or banks depending on what it takes for each of your devices to charge from completely dead to 100%) charge your banks before you leave and and bring all of it. Only charge your devices off the solar panel until it starts getting shitty out and then you'll have your batteries to back you up in foul weather.
Depends on how you define worth. If you're thinking in financial terms, you can never break even the cost of the solar panels from merely charging the phones. It's more likely that the equipment breaks down first.
Solar panels have a longer life span and work far more efficiently when they are cooler so it is best not to have them laying on the ground and a black pouch may not show the dirt but it is a seriously bad idea in helping the panels to retain the heat.
you should have suited it up with an meter..s32.postimg.org/vm3e3yv7p/WP_20160519_18_39_59_Pro.jpg to see what wattpower it actually delivered and if the spec 28w was on call with optimal sun.. judging from your charge-time.. it couldnt have been fare from that, so the 28w seems legit.
I know this is 4 years to late but I just found the channel. I clicked the amazon link for the panels but it directs me to a cable... Is there a current amazon link for this product? Or something similar? Thanks
You can also angle the solar panels at 30degree's towards the sun. (flat on ground is not the best or fastest charging way). Depending on your location, it must be 30 to 45degree's angled towards the Sun (some websites can tell you which direction is the best for your location. I'm In Cape town, South Africa. So for us it must be 30-35degree's maximum... not above 35degree's and for my region the panels must face North.
People should also remember that there's different types of solar panels and since solar is being constantly developed don't expect a cheap product necessarily be as good as a more expensive product. You get what you pay for.
I'm in bkk would have been cool to meet you. hope you got out to an island or the mountains up north. Bangkok can be a drag. Thanks a lot for your great videos.
Huh, so this unit uses SunPower PV panels @ 23.5% efficiency. Not bad for silicon-based technology! That made me sad, however, that the 31.6% efficient Alta Devices GaAs-based panels have never seen a widely available product to this day. It's like the Chinese company that bought them, Hanergy, is just sitting on their acquisition. That's just maddening!
