Hello everyone, today we will see the solar panel Blitzwolf BW-L1 sent for the occasion by Banggood, whom I thank for the opportunity and trust given to me.



CLICK HERE to go and check for it on the official website of Blitzwolf.

I want to clarify that the reviews are done at the amateur level and without the aid of scientific instruments or test in secret Labs therefore, between the lines that will follow, will be my humble impressions.


Official features taken from Blitzwolf:

- Technology:SunPower
- Transition Efficiency: 21.5%- 23.5%
-Output 2: 3Max
-Total Power: 20W
-Weight:550 g
Size: open-270x675x4mm; close 270x150x28mm


Where to buy it

The solar panel can be purchased from the e-shop Banggood where you can use the discount code "414ede" which was reserved to me. Don't miss the opportunity to buy it at a glutton price.


The packaging and accessories

The solar panel comes in a minimalist paperboard packaging, in fact on the front is written only the name of the brand.



On the back, always to respect the minimalist look, we find the various certifications such as CE, RoHS etc.



to one side was stuck a sticker with the name of the product, a barcode and its SKU that belong to shop Banggood.



By opening this package, we find the contents well sealed in a plastic bag. On the inside of the lid of the packaging lists the thanks for choosing of Blitzwolf.



Once removed everything from the packaging, we should have:

- Solar Panel
- 4 small carabiners (obviously not suitable for climbing but which will be used to attach the Panel with the 4 eyelets predisposed)
- a USB-> micro USB of the length of a little over a meter
- the manual in English
- a slip of paper for warranty(18 months)



To follow, the pages of the manual.




The solar panel

This solar panel is the largest (thinking on  powers/n. panels) from those sold by Blitzwolf House.
The "body" externally consists of cordura, suitable material to resist abrasion and offering minimal protection from water sprays. Being the Panel composed of Electronics material, i advice to minimise the water exposure.
On the body, to the outer sides of the panels, there are 4 eyelets that allow you to attach the carabiners 4 founded in the package, or allow you to let them go in directly the paracord, in order to secure the Panel to the fabric of a tent or a tarp, obviously keeping it always turned towards the Sun.

The Panel will opens up into four sections: three consist of monocrystalline modules, while the fourth has a pocket suitable for the charging cable and/or other small/medium sized objects.
The pocket contains also 2 USB outputs smart port, since it can understand needed current by the device attached and adjust the output.
According to data reported by Blitzwolf, the conversion of solar radiation into electricity has an efficiency of between 21.5 and 23.5% and the current output up to 3A.

The Panel and the inner pocket is kept closed by a well sewn velcro strip.

Here's the Panel completely open. Stand out well the four sections and placement of 4 eyelets.



Below here is the picture of the side flap, inside which there is the pocket, on which is printed the name of the brand and the power of the panel, its technical characteristics with various certifications and drawings that tell you how and when to use the panel, advising against the use of the panel under the rain.



Closeup of doodles. As long as there is Sun or is cloudy, the Panel can be used safely. With the rain it is not recommended the use.
,


Looking the Panel behind, the only things that stand out are the velcro strip that allows the closure and logo and the blue strip with the power of the Panel. There is no additional element that can act as a tripod.



To the left of the first panel there is a small "5th" flap that host two of the four panel's eyelets.



And here's the view inside the little pocket. In addition to the small strip of velcro there is the little box with the 2 USB outputs ports.




The tests performed

Let me start by saying that, due to the solar reflections, pictures of the tester does not come out and then I decided to not include them.

Various tests were performed on sunny days or fleeting cloud and, in the various test, I used only one USB port that both. To measure the values I used two XTAR tester and I put in charge a cellphone and a power bank.

On sunny days the panel, using a single port and depending on the connected device, is able to deliver 1,3A or 0,90A. With both ports exploited, manages to deliver 0,87A in the 1th and 1,10A in the other.

With the fleeting clouds, the value dropped to 0,50A in a test with 2 connected devices. The charge, if it is decreased or interrupted by a shadow or a cloud a little denser, will resumes automatically after the interruption.

In the single test, I also chargeded an old mobile phone with a battery of 2600mAh nominal. The test lasted for half an hour and I the battery was charged of 10% every 10 minutes.

The benefits provided by the panel are very high, keeping in mind that the panel must be oriented toward the Sun with the most optimal tilting possible.
To demonstrate this, among other tests, I also stuck a last generation phone that can be reloaded with rapid charging. And it let me score the value of 1,3A.

I believe that, with more "energy hungry" devices and in better light situation than mine, the panel can deliver more current. Of course, in the worst condition than tested mine (keeping in mind that at the time of writing it's summer) the panel output will be less.


How does that work

The only operations needed to use the solar panel are to open it completely, exposing the three panels directly toward the Sun, taking care to adjust the angle in the most optimal way possible and link the device that you want to charge.
As this model does not have parts that act as tripod, the ideal would be to find a trunk of a tree, a fence, a slope, a rock or a small wall in favor of the Sun and leave it resting for as long as necessary.
If you must stay in a given area for a long time, remember to have the foresight to rearrange the panel every 20-30 minutes since the Sun will change angle.




Dimensions: dimensions and weight

The Blitzwolf BW-L1 when open measure 66.8x26, 5x2* cm. When closed it measures 26.5x16,3x4* cm. The single panel measures 24x12, 5x0.4 cm.
Weighs 510 grams and a single carabiner weighs 7grams.

*= into the thickest part

To follow the dimensional comparison Aukey PB-P3.



The length of the shorter part of the Panel is very much the same.



Something that cannot be said of the length of the longest part. The longest is the Blitzwolf and with another panel in addition, but the size of the single panel is lower.




Personal considerations

The Blitzwolf BW-L1 is a solar panel with right proportion size/performance and I find it very suitable for the outdoors use. As a simple campsite as for a several days outgo to explore the various trails that span the mountains just as an example.
It may also be a valuable ally for those who plan to build from scratch a BOB or for those looking for a product to be able to be integrated to a BOB that already exists.

In my view, it must be joined to a power bank that you can charge and store the energy produced. This because, charging directly a device that being used, you risk the damaging of the battery for current rushes.
Since both USB outputs ports have good performance (> to 0,80A in good conditions), you can even consider buying a power bank of 20.000 mAh with two microUSB input so you could charge it as quickly as possible and dispose of it during the night if is necessary.

I remain fixed on my thought that the Panel should be used while stationary in order to take full advantage of its power but, if you can't stand still and the only solution is to attach it to your backpack, know that the charge will suffer because of the many interruptions.

I have not found serious faults on this model. The materials give a feeling of strength and the placement of the 2 USB connectors is not uncomfortable.
I enjoyed the presence of the charging cable in the box, so with one purchase you are operative. But I still  recommend to buy some high-performance cables (I'm  not saying that one issued is less performing) with a good thickness and at least 2 meters long and with the outer sheath reinforced, so that it can put the devices in charge far enough away from the Panel leaving them in shade and avoiding unnecessary overheating.
