We present to you the 2018 rating of Power bank with solar battery with technical characteristics and customer reviews.
When choosing a Power bank with a solar battery, it is the latter that plays a decisive role, so first a little theory.
| Efficiency of solar panels | in percentages |
| Monocrystalline | 17-22% |
| Polycrystalline | 12-18% |
| Amorphous | 5-6% |
| Cadmium telluride | 10-12% |
| Copper indium selenide | 15-20% |
| Polymer | 5-6% |
As you can see, the efficiency of different batteries varies very significantly - from 5 to 22% (4 times). At the same time, manufacturers rarely indicate the type of batteries used, but if we take that the average area of a Power bank solar battery is 100 square centimeters and the power it produces, in the most optimistic case, is 150 mAh, then it will take more than 60 hours to charge a 10,000 mAh power bank, which means during daylight hours (12 hours) it will charge 20%.
Well, now to the rating itself:

Reviews
pros
design, capacity, solar battery
Minuses
large and voluminous in size
A comment
I bought it mainly for hiking, to use with a portable speaker. Of course, it takes up a lot of space, but I am confident in its durability, since the connectors are protected from moisture and debris, as well as resistance to mechanical stress. The USB connectors are located vertically, making it convenient to charge several devices at once.
pros
Decent volume, enough to charge a smartphone 4 times. Comes with a protective rubber bumper. It has a carabiner, meaning it can be attached to a backpack. There is a solar battery on the back side, that is, purely theoretically, it can be charged through it as well
Minuses
You can charge from two USB ports at the same time, but only one charges faster, the second slower
A comment
I decided to buy this one because it is shockproof, protected from dust and moisture (purely theoretically, I haven’t tested it). Well, the presence of a solar battery will still allow you to charge it on a hike in a pinch.
pros
It came complete with a shockproof bumper with a carabiner. On the reverse side there is a solar battery from which, theoretically, it is also charged. The battery capacity is quite normal. 10,000 is enough to charge both a smartphone and a camera
Minuses
It weighs decently despite its size due to the metal body. The solar battery charges slowly
A comment
I bought it because my passion for hiking intensifies in the summer. Therefore, a portable battery becomes very important. And this model is very well suited for this task. That’s why I bought this one even though I came across cheaper ones with a larger volume
pros
capacity, moisture protection, 2 ports
Minuses
weight
A comment
I bought it as a gift for my friend, the original design, not like everyone else, that’s why I was interested in it. USB inputs are located vertically, which makes it possible to simultaneously charge several devices. I tested the charger on my phone, it charges completely in about 1 hour.
Minuses
Big enough
A comment
The battery capacity is quite decent – 10,000 mAh. It takes you to charge your mobile phone four times. It charges completely overnight – from the last bar on the indicator to full scale. So far it functions as stated by the manufacturer. Duration of use – 4 months
A comment
The solar battery is not very useful, mainly to compensate for the work of the flashlight.
pros
Compact and lightweight. into the protective bumper. Fully charges the phone/player, provided that it itself is fully charged. For some, a flashlight might be an advantage.
Minuses
I don’t really understand the presence of a solar panel. In reality, it charges 20% per day. By the way, it charges quite quickly from the network. Completely in 8 hours.
A comment
In principle, the model is good. The price suited me. I haven't seen any serious flaws in it yet. Special thanks to the manufacturers for including a large number of adapters for all common connectors in the kit.
Minuses
flashlight
