Anker PowerPort Solar (21W 2-Port USB Solar Charger) for

The Anker comes with an 18-month warranty. If you are in the market for a solar charger this one is top shelf! Incredibly Durable: Industrial-strength PET polymer faced solar panels sewn into rugged polyester canvas offer weather-resistant outdoor durability. 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. 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. Before we get into the ins and outs of which models are going to be best, it’s only fair that we give you the negative sides of solar chargers. Solar charges are expensive (more expensive than regular chargers or power banks). They’re fairly inefficient too, they take a long time to charge from the sun, can only be charged up when there actually is some sun, and tend to charge phones pretty slowly.We’ll be honest, most people don’t need a solar charger. For most of us, a regular charger or power bank is the cheaper and more efficient option. However, if you often find yourself away from a power supply, if you’re a big camper or outdoorsy kind of person, or if you prefer using the sun’s energy rather than burning fossil fuels to charge your phone, then a solar charger might be for you.

On a size/weight basis, assuming everything worked perfectly, the Powercore 20100 would hold 12 hours of sunshine. ( 20100/1700 = 11.8) It weighs 12.6oz. The Anker 15W weighs about the same (right? Put these on scales). In perfect conditions you’d need 2-3 days of sunshine to get the same energy as the 20100. Do you need 2-3 days worth of 20100 charge more than the 20100 can carry in itself? Well mostly not, you’d need to be off-grid for a week or so before solar makes any sense. And then if you were off-grid for >1 week you’d be better off with a bigger solar panel on a Watts per weight basis. You’d be better off with a group of people and between the group having a bigger solar panel, then the sunshine is much less likely to drop below the threshold voltage of your devices, i.e. it is useless less often. Gaming Let expert reviewers guide you on which games to play. From consoles to RPGS and shooters, we’ve got it all here just waiting for you to read.Gadgets & Smart Home Whether it’s a drone, a smart vacuum or noise cancelling headphones you are looking to buy, our reviewers have tried and tested it before you have to. 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. 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). it is a pity you didn’t seek more advice earlier, but given where you are now: test and eliminate cause (cable, solar, Powercore).

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. Ensure that PowerPort Solar is in direct sunlight. This charger does not have the capability to store power, so it can only charge with power converted from sunlight.

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 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. Solar (in general, not specific to Anker’s products) delivers usually about half what is claimed for a 15Watt I’d assume 7W (its been measured at 7.2W) so usually in perfect conditions I’d expect about 1.6A 5V. In less than perfect conditions the volts and the amps drops. If it drops too far then it ceases being able to be above the threshold of whatever it is output to. Different devices have different thresholds so some are more tolerant of less than perfect conditions than others. So the larger the solar panel, the less often it drops its output below the threshold of the device, i.e. larger panels are useless less often. 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.
