Please tell about series connections because I'm trying it but the current is same not the plus. For example one panel is meximum current 0.7 mah and two panels current 1.40 mah
I connect them in a way to increase ra w voltage . For example , i got 6 volts on each panel , combined they are 12 volts . and as the amperage is function of voltage - if there is enaught voltage and low resistance - the current will flow ! Now i have 5v 1.6A /steady/ solar charger. If you connect them in series there is a rule that the amperage will be the amperage of low sell. Enjoy
@@dpher1 what do you need exactly ? I connected them with cables. The panels are in series. I use cheep Chinese voltage converter at the end of the panels. ask what you need.
You should place the panel on top of your backpack facing almost up (e.g. in LA on June 21 at noon the sun is ~80° almost up). Whereas when the sun is already setting - it's not worth to put the panel on your back facing horizontally towards the sun, because sunlight is much weaker and won't charge via a small panel. I've tested this theory in practice several times.
You are absolutely right. I still got the panel, but it only works with certain models, and my current phone is not one of them. But surprisingly good small panel if used correct.
@@BackonTrailasia I'm surprised to hear that there are incompatible phones (as long as you have the right cable). After watching your video I ordered 2 very similar panels that I will connect with Y-shape USB cable (for less sunny countries), but for sunny countries use just 1 panel. I previously used an older 3-section foldable model - shockproof, waterproof, but charges barely enough for smartphone or camera and only in tropical regions on clear days. I heard from several reviews that the newest solar chargers are much more efficient.
@@reinis.berzins I was just lucky when I got the panel, that it worked with my phone back then. Only realised it was luck when I got a new phone and it did not work. Carried the panel with me at all times not knowing it was for nothing. Now I rely on a panel called Elegeek, which seems to be 4 similar panels like the small one, and it has 9V - 18V DC out + USB OUT 5V - 2A. Best panel so far, if you are not too concerned about bulk.
I would really not rely on these board for anything, unless you are in a static position with perfect light on the board. Tested it i various conditions, but just did not do the job. But perfect if static and aligned with the sun.
I found one in a hiker box on the cdt. It only works if you use a battery bank to recharge. The phone will go on and off screen wasting more than the recharge rate.
3:53 These are fake characteristics! In fact, a good manufacturer would indicate a power of 5W for this panel - this is exactly the power that the solar cells used in this panel have in their maiden state, that is, when they are not cut and not laminated with a protective coating. Of course, you won’t be able to get that kind of power from the panel’s USB port. Most gadgets that require power supply voltage will be able to receive 2.5W power from this panel. This power is enough for slow charging of many smartphones. They will be charged from it at the same speed as from a USB 2.0 port on a computer, which also produces 2.5W power. Some modern smartphones may refuse to charge directly from this panel, and then you will have to charge the power bank from it, and then the smartphone from it. Some power banks capable of charging at a very low voltage will be able to get about 3.2W of power from this panel at a voltage of 4.2V. Such a socket, when used correctly (when it stands on the ground or other stationary surface all sunny day, correctly oriented towards the Sun and no shadow falls on it), will allow you to receive a current of approximately 6000mA on a cloudless summer day, part of which will then be lost when charging the gadget . If you plan to charge a power bank from the panel, and only then charge other gadgets from this power bank, then these other gadgets will ultimately only be able to receive about half of the specified amount of current, that is, to charge a smartphone with a 3000mA battery, you will first have to stand in one place spend 7 hours charging the power bank, and then some more time charging the smartphone from the power bank (for example, my smartphone takes 3.5 hours to charge from the power bank). One can only guess how much time then you will have to move along the trail...;) In cloudy weather, this socket will practically not work and you will have practically no reserve of electricity for this case, unless of course you take a separately charged power bank with you for such a case. Think about whether this is enough for you. Think carefully so you don't end up being disappointed and telling people that using a solar panel on a camping trip is a bad idea! Personally, I use the AllPowers 21W solar panel, which, weighing 475 grams, can actually output up to 13.5W of power through its USB ports. In practice, this means that in 7 hours of a cloudless summer day, this socket is capable of charging a 20,000mA power bank from 0% to 100%, and you still have time to recharge your smartphone from it. As a result, I will have not only a reserve of electricity for the next smartphone charge, but also a couple of more smartphone charges in case of cloudy weather. If I don’t need such a large amount of charge and only need to compensate for the charge in the power bank spent in the evening charging my smartphone, then an hour at a lunch stop will be enough for me, and in the morning, while I’m packing the tent and my things in the backpack and having breakfast, this socket will replenish the smartphone charge that he spent at night. If you think that a panel weighing 475 grams is too heavy and you don’t need a lot of electricity since you rarely use your gadgets, then in this case you can consider the option of the AllPowers 15W solar panel, which in my opinion is the smallest a panel that is worth taking and that can really provide you with electricity while camping; one person traveled with such a panel and a power bank which he charged from it for several months and during this time he did not have the need to charge from a regular power outlet.
Why does the AllPowers panel have print that states, "anti-cratch hardened PET " what the hell is "anti-cratch" I don't think it is an genuine AllPowers® panel.. it is probably a cheap knockoff.. ALLPowers is not that careless.
It does not work with my current phone so have misplaced it but pretty sure is is a cheap Chinese version. But worked flawlessly for the right model phone. :-)
I use two of them in series in my week trips in mountain.
Very useful little panels.

@@Psychosapiens do you have a link to what you used to join them in series?

ask what you need.
2 usb into 1? Don't you need to join the panels together in series and then into a usb controller output?

The generic 10W 5V board looks rather interesting! I'd buy it then. Also, how would the generic board behave on top of the backbag?

Most is bought at places like Lazada.com, Ebay.com, Aliexpress.com and Banggood.com.
