UPGRADE Topsolar SolarFairy 30 Foldable Solar Panel 30W Portable Battery Charger Kit for Cell Phone Power Bank Car Boat RVs Off Grid Charge 12V Batteries & 5V Device

There is a 19V/1 label on the raw solar output. I am using 4A, which is almost 30watts. There is 27 watts in this device. But the measurement by the manufacturer appears to be the Open-Face Voltage at circuit junction A 0 volt battery, the short-circuit current (*1, a 1). 4 Amps) and simply multiplied that by 27 Watts to get the bogus result. According to my measurements, I measure at 5 inches. A connector with a diameter of 5mm, a voltage of 14 volts at the maximum power point. MPP Current 1. 0 at 6V and MPP Voltage 1. 0 at 6V A 32A maximum power means a 19W maximum power. It's 3 Watts. measurements were taken at noontime, normal to the sun, at high altitude, under a clear blue sky, with low humidity. I would say this is pretty much in line with the standard test condition of 1000 Watts/square foot. Measured in meters. *Hoping manufacturer might publish some certified test data in order to solve this conflict. Important to know since the solar panel will be attached to a backpack and we want maximum energy output in the backpack. There are a lot of nice connector options, but remember to use the USB to *14volt adapter for regulated output. I like the way this has been done.

This is a nice solar panel that's compact. This adapter kit came with a transport bag During the time of the photo, there was 20 volts of power and the weather was overcast. This foldable panel was a very good product both in quality and output. A bit smaller than my 70 watt panel would be more convenient as it can be cumbersome to lug The battery fits very nicely inside the case it came with and it folds to be about the size of a notebook*. I plan on using it with my ham radio go-kit battery to extend my time on the air. I was impressed with the quality of the app and how rugged it appeared to be. It appears to be a very good product.

solar panel so that my solar generator could be charged. After contacting the company about my concerns regarding the panel, I learned that the activity light was supposed to change from red to green when the panel was charged, but it did not. Even after twice writing my concerns to TP Solar, I have not yet heard back from the company. It seems that the panel charges the generator, but it does so at a very slow rate. While this is taking place, the indicator light remains red. In short, the instructions that accompanied the panel don't provide a great deal of information.

The array of adapters is nice. A sunny day in Texas gave me about 1% charge every 5 minutes or so on my Jackery Explorer. It was easy to use and did not require a powerful adapter, one of the included tips worked fine in the Jackery's Input socket and showed up as charging a short time later. The device has alligator clips too, so a battery can trickle charge. This bag also has two carabiner clips and holes so you can attach it to a backpack or use it as a hook. I was interested to see that the solar panels are not glossy and do not immediately look like solar panels, but are rather rugged and have what looks like a matte finish, although I am not familiar with what types of solar panels are on the market today. It works, it was a good purchase, and it worked well.

Having not yet used this in the field, this review is more of a first impression than a full The majority of my impressions are positive. My first impression of the panels is that they are very sturdy and thicker than I expected, but they seem quite portable and several adaptors included, as can be seen in the photos, but there doesn't appear to be one for the USB port An adapter for the C port. It's likely you will need a USB thumb drive Beginning with A to the end of If you want to use it on a mobile device, this will need an adapter. Instead of a USB female connector, this does not seem to have one. The problem could easily be solved, but it seems odd that it was overlooked. Apart from those small issues, it seems like a solid deal all in all.

Be smart about it. This power bank may be equipped with one or both of these panels. I think it is a good idea to spend an extra couple of dollars. Alternatively, be frustrated and ask yourself why you did not listen to your gut when this was right for you. I was the one who did it. During my camping trip, I bought three other panels for recharging, and I admit that I shouldn't have bought them, but I did. Stay safe and have a good day.

When I took my cellphone with me on a camping trip, the direct sunlight did not allow it to charge. When the phone was turned off, the charger was left to charge for hours, but did not get over 1%.

It was designed to work with power banks with MPPT input and an unregulated barrel jack output. Using an Omnicharge power bank directly in the sun, I was able to get up to 22W out. This is a nice 6ft tall. Having the barrel jack cable and carrying the nylon case is nice. The case fits the panels and accessories securely and tightly. Camping with this would be a blast.
