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.

Though the Anker PowerPort Solar Lite’s measured average (6 watts/1.17 amps) was less than the 15 watts/2.1 amps advertised in the specs, it peaked at 8.48 watts/1.67 amps in direct winter sun, and that real-world performance was in line with the best of the competition. After filling up from the PowerPort all day, our test battery discharged only 15 per cent less power than the battery powered by the much larger and heavier RAVPower charger.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. As the phone gets hot, it defends itself by not ingesting as much power, so in the same situation the solar panel is working well, the iphone will respond badly. As well as the big things mentioned above, there are other things that you’ll want to take into account when making your decision: 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!

buy the biggest solar panel possible, the reason being in less than idea conditions, a bigger panel output will be more likely to be above the required minimum threshold of your devices. 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. The 15W Anker panel should charge your iphone at close to full speed in strong sunshine, that is why it is so consistently highly reviewed and a good answer in sunny areas, wait for strong sunshine then try it. If it does then do this in sequence: Why did you buy the Powercore 20100? You describe the use of tearooms and mains power whilst there, well then you’re looking for fastest recharge. The 20100 has one of the worst recharge / mah of the Anker product range. Two Powercore 10000 would recharge twice as fast in total than one 20100. Or the Powercore II 20000, or the Powercore 26800, or… (QC or USB-C, etc). BigBlue makes some of the most popular solar chargers, and this model is the ideal choice. You get plenty of power, great amperage, and a digital readout so you can see exactly how many amps are going into your device. It’s got two charging ports, and comes with metal hooks included so you can easily attach the panel to your bag or a tree to allow for easy charging.

If you are doing all of those then the Anker 15W panel should be recharging an iphone at about the same speed it the iphone would charge off mains power (e.g. off Powerport2). If it is not, then eliminate the cable as cause, then if not then its probably the solar panel’s fault. The panels themselves are super efficient, and the device comes with hooks so you can easily hang it on your bag to catch the sun during the day. It’s rugged and durable thanks to the high-quality base material. And you get a short circuit, overcharging, and power surge protection too. Monocrystalline solar panels are much more rugged than CIGS panels, so they’re much more suited to being outside. They’re also heavier than CIGS panels though, but despite this, they can still be bent and formed into different shapes. They’re also the most efficient tech, getting around 22% efficiency. Most portable chargers you see will use monocrystalline panels.

The sun won't always be out when you're on a camping trip, out at base camp, or just looking for a charge from the sun. An equally important metric is how well a solar panel works when the sun isn't directly out. We tested the panels in full shade and partially shaded conditions and saw how much each panel put out.Weight: Keep in mind that you’re going to be carrying this charger with you when travelling, and every little bit of weight adds up. You want something light and portable. The Anker comes with an 18-month warranty. If you are in the market for a solar charger this one is top shelf! Entertainment We spend hours watching and reviewing the latest movies, shows and music releases so you don’t have to. A full 10,000 mAh power bank should be able to charge the phone fully three times. But could any of our solar chargers generate enough power to fill a 10,000 mAh power bank during a 12-hour walk? The answer was no.

is 42% more power for 32% more weight, because the solar part becomes a larger component of the rest of the system. Also the voltage drop off is less. It is the voltage drop-off which is the most critical part, if it drops below the charging threshold it is literally then useless, in fact less than useless because some devices will detect a voltage, open their charging circuits and then not get enough input to offset the charging circuit and so causes the device to discharge rather than charge.The Anker PowerPort 21W solar charger is very durable. It uses industrial-strength PET polymer faced panels that are sewn into a rugged polyester canvas. The canvas offers weather resistance. I did not have the opportunity to test the panels in the rain but I am sure they would hold us just fine. However, I suspect they would charge much slower in overcast rainy conditions. In terms of convenience, this device is as good as it gets. It’s plug and play, so use is intuitive. It comes with hanging hooks, allowing you to hang it pretty much anywhere you please. And it’s fully waterproof, always a good idea in the outdoors. Thanks to the fact that its nylon it’s pretty rugged too, though not quite as durable as one of those military grade battery integrated chargers.
