I use a folding solar panel (Anker) and 2 separate 10,000 mah power banks. One is used to recharge devices, the second can be recharging easily even on overcast days. I normally carry a 5,000 mah phone and either a tablet or phone of similar mah. The second device is used for Media consumption. This system has kept me going during power outages (usually hurricane) or camping. Peace

IMO the biggest flaw of all portable solar panels out there (i.e. ones marketed to backpackers...as in charge while you're moving) is that they only have USB-A port(s), each with a typical 5V/2.4A (12W) max power output. This is always less than the theoretical max power output of the whole panel array. This means that if your strategy is to charge only one power bank and then use that to charge up all your devices, you're only using 12W from the panel and wasting the rest! The only (less than ideal) solution is to plug in more to one power bank to the solar panel to not waste that (potential) extra wattage. IMO, portable solar panel manufacturers need to include USB-C PD ports that can output more than 12W.

@oleganonimka3725

Жыл бұрын

Here you need to take into account several nuances. Firstly, for example, my AllPowers 21W solar panel can output power up to 13.5W (5.2V x 2.6A) from one USB port, although the manufacturer promised only 12W. That is, in fact, all the electrical power that a solar panel can give out, I can get from one of its USB ports. More power from this solar panel can only be obtained if connected directly to the solar cells of the panel to avoid power loss that occurs in the voltage converter in front of the panel's USB ports; then you can get 14.5W, and possibly all 15W of power, but no more. The problem you mentioned may occur on large solar panels such as the BigBlue 28W in fine sunny weather, but many will find such a panel too heavy to carry in a backpack. Secondly, you need to understand that not every power bank will be able to accept even 12W of power at a voltage of 5V when charging. You still need to look for such a power bank. In general, there are a lot of power banks on the market that are poorly compatible with charging from unstable sources of electricity, and this should also be taken into account. Usually, the dumber the electronics of the power bank, the better. Thirdly, you need to understand that marketers indicate the power in the name of the panel. They just pretend that the solar cells in the panel have the power that their manufacturer claims. However, the manufacturer, when declaring the power of a solar cell, meant a whole plate of a solar cell, and in modern solar panels this plate is most often cut into 6 parts, despite the fact that the solar cell manufacturer SunPower does not recommend cutting them into more than three parts. This cutting results in a loss of power. In addition, in solar panels, the solar cells are laminated with plastic, which also leads to power loss. It turns out that in fact my AllPowers 21W panel, for good, should be called AllPowers 18W, and the BigBlue 28W panel should be called BigBlue 24W. In addition, you need to understand that such power is possible only when the solar elements of the panel have a temperature of 25 degrees Celsius, but in reality, the panel very quickly heats up to 65 ... 80 degrees Celsius in direct sunlight, and each extra degree above 25 degrees Celsius reduces solar panel power by 0.35%...

Most of the 14-28 watt (2 & 4 panel) solar chargers output 5v 2.4A per usb max. The difference between the two is that the 4 panel can output that to both usb ports (in theory). So yes, it was excessive heat, not the solar charger having 4 panels. Volts times amps times power factor (which is at 1 aka unity in this application) equals watts. They don’t even output 28 watts. Lol

Looks like the SunJack 60W "portable" (~4 lb) panel has a USBC-PD port with a max 45W output and a USB type A outputting 18W max (for QC3.0 compatible devices). It even has a DC5521 plug with 19V max output. SunJack also has a 25W version with a USB type A and a USB type C port but the type C port maxes out at around 15W. Not sure why no manufacturer allows the USB-C port to output all available current from the panels. Sharing power output between ports is nice and all but if you're just charging one device, that's wasted power going to an empty port!

I have three (3) "BLAVOR PN-W12 Pro" Solar power pack battery with solar..... instead of 1 solar panel, it has 4. If drained, it takes 4 days to charge up by solar. The Panels are good if camping and keeps it topped up. The Battery is "20,000 mAh" but it can't fully charge my iPhone XR only 3/4. My iPhone has 2,942 mAH battery.... so..... feels like really a heavy 2,000 mAh. That is the Bad (Posted negative review on Amazon, $45) ...the company sent me two more free... but they both had the same results. The GOOD is the very bright LED lights last a LONG LONG LONG time. Like 10+ hours on full charge.. that is impressive. So BAD, in charging a smart phone, GREAT for camping and bright BRIGHT LED light... and a compass also. This one does not have wireless charging... USB 2.0 and 3.1 charging (I checked the output, only 2.1 Amps at 5 V each. I have older type that have wireless charging and 5 (five) panels... still "13,000 mAh battery" but really, 2,000.
