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. 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.

There are three basic kinds of solar chargers that all use different technology. The three available options are: CIGS 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. 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. Other than the technology used to make the solar panels themselves, you’ll need to think about a few other things before making your final decision: Output Power

If you’re looking for a beefy charger, then this RAVPower unit might fit the bill. IT gets a full 24 watts at 2.4 amps per charging port for each of the three USB ports, giving you plenty of power there. You get a big solar surface area to capture more sunlight, but a fairly portable design in that it folds up nicely to slide away into your bag.

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 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).
However, a few times I used the Anker solar charger to charge my cell phone directly from the charger and it only took a couple hours to achieve a full charge. I noticed the charger worked better in direct sunlight which makes sense. 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.

When we’d got our preliminary list it was time test the products for real. Based in Yorkshire with some fantastic hikes and walks a stone’s throw away we know a thing or two about the great outdoors. The only issue in late September would be the Sun but thankfully during our testing weekend, we got clear blue skies and reasonable levels of sunlight. PC & Peripheral All you need to know on the latest PC releases and whether they’re worth their dime. Best for: No one really, CIGS technology doesn’t make for great portable chargers since the panels are just too fragile to be outdoors for long. Monocrystalline
This post was done in partnership with Wirecutter , a buyer’s guide to the best technology. This is a condensed version of The Best Portable Solar Battery Charger ; read the full review here . You’re welcome. Correct you cannot connect Powercore to be recharging it at the same time as take output from it. That is called pass-thru and doesn’t work on the Powercore 20100. 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.
