Fortunately, the Anker allows you to connect two devices into the power port. If you are connecting devices into both ports on the solar charger it delivers 2.4 amps per port. If you use only a single port it delivers 3 amps. Charging more than one device is critical at times but also slows down the charging process. However, I’m starting to get a bit frustrated now! I have my 20100 charging from my PC and at present it is charged up to 50% and flashing away continuing to charge up to full. So it’s at two blue dots. All good. Given what you say, I think probably your solar panel is at fault. The reason is you said neither the Powercore nor your iphone show a charge input, given its 2 devices with 2 cables, by elimination is probably the solar panel fault. The top performer was the Anker Powerport Solar 21W which managed to give the RavPower enough for two full charges of the Galaxy J6. The 7 others were all just slightly behind. Based on our testing we think you’d need around 12 hours of strong sunlight to fill a 10,000 mAh power bank which won’t be a problem in many parts of the world, but in the UK? Not very likely!

I have to say although I did manage to get the gist of what you said I am really not very techy when it comes to some of the V & Watts language and calculations. and for someone like me as a layperson, some of it is a bit over my head.Thanks again Nigel for alI your great advice and help. I do think I need to give it another shot in full sun which I will do the next sunny day (hopefully soon!) however I don’t imagine there will be full sun at all times on our trek so I really do question the sensibility of carrying the excess for very little return. I did start out behind glass but then moved outside in direct sun and angled accordingly to make the most of the moving position of the sun. Just before we get on to our model recommendations though, first we should tell you how we went about choosing which models went on our list. We looked primarily for a good balance between price and specs. We choose to disregard CIGS solar panels as they’re simply too unreliable for outdoor use. We obviously looked at all the important points that we mentioned above as well.

SOLAR CHARGER FOR THE BACKCOUNTRY THE BEST 21W SOLAR CHARGER FOR THE BACKCOUNTRY

in full strong sunshine (it only takes a modest overcast to drop such a small 15W panel below the threshold for most devices to charge) Waterproofing: Is the charger waterproofed? This isn’t an absolute necessity, but there’s always a chance that you’re going to leave the charger outside in the rain, or even spill something on it, so waterproofing could be a good idea.I then changed the cables and attached my iphone directly onto the solar panel. I had tried this earlier. At no time when I have tried this has the charging (little lightning bolt) shown that it was charging. Again no red light on the panel. I have now had my iphone attached to the solar panel for the past half hour. It has not budged and no lightning bolt showing it is charging . It appears that apart from the odd intermittent red light coming on in the solar panel then switching off again, when I first plug into it, the solar panel is really doing nothing at all in the way of offering any charge to any device using any cable. CIGS stands for copper, indium, gallium, and selenide, the materials used to make the panels. These kinds of solar panels are very flexible and light, however, they’re also easily damaged and fragile. For this reason, you probably won’t find many options for phone chargers using CIGS tech. They’re also the least efficient of the three technologies, getting only around 16% efficiency. buy the Powerport2 and two Powercore 10000. These would collectively recharge your Powercore twice as fast when you do come across mains power. Two Powercore 1000 weigh the same as one Powercore 20100, and recharge twice as fast, if one of them fails you still have the other. The Powerport2 outputs 4.8A which is enough for full speed recharge of two Powercore 10000. In the case of a Powercore 20100, I don’t know what is its threshold, the minimum voltage which would cause it to recharge, but that is my 1st thought. Best For: Pretty much everyone, this is the most widely available tech for a reason, simply because it’s the best choice for a solar charger that you want to take outdoors. Polycrystalline

If you’re looking for a big yet affordable option, then the Floureon Solar Charger is for you. You get a whopping 28 watts and 7.2 amps across three USB ports, so there’s more than enough power here, and that 23.5% efficiency is pretty impressive too. The main thrust of your text is showing the realization about the core problem with solar, that is mostly useless for most problems relative to a charged powerbank. Solar makes little point on size and weight reasons on shorter trips, and becomes less useful the smaller they get. The next model up from Anker is 21W. The polyester canvas pouch and base make for a rugged and durable charger that shouldn’t suffer from being shoved into a bag. You get short circuit and surge protection, as well as PowerIQ to ensure that your devices are charging at their maximum speeds. You also get a fair amount of waterproofing, though your actual phone won’t be particularly protected, so you’ll need to be careful of that.The Anker comes with an 18-month warranty. If you are in the market for a solar charger this one is top shelf! After reading your reply, I removed the 20100 from the solar panel and plugged it into my PC USB port. Instantly the first 2 blue lights appeared on and the charge started. That hadn’t happened at any time when attached to the solar panel.
