Spec looks good, although this FAQ question gave me pause:

freeme wrote:

6. How long is the life span of the BW-L3?

The PET panels will gradually fade when exposed to the sun resulting in reduced output over time. If used properly, the life span of the solar panel is approximately 4 to 5 years. After this time, the panels output may be too low to provide an adequate charge.

Most solar cell manufacturers warrant a 25 year service life for things like rooftop modules. The 4 to 5 years specified by Blitzwolf seems very short in that context. Is there a reason why the service life for this portable panel is so much shorter?

I believe it’s because these portable panels are subject to more use and abuse being stuffed in a backpack, folded and unfolded numerous times and are generally put in harm’s way much more often than a rooftop panel. True, rooftop panels must contend with weather, but they aren’t being physically manipulated over and over. My thoughts anyway.

PET, polyethylene, is going to get damaged by the sun. You’re not going to see much of that on roofs.

The low mode should be lower.

Good point, that makes sense.

The problem’s not the solar panel as such, it’s the tradeoff between PET encapsulation being lighter and less fragile but subject to UV damage, or toughened glass being UV proof but very heavy.

I already have various panels with PET encapsulation, and I haven’t seen any degradation yet, so that puts my mind at rest. It also occurs to me that UV damage tends to be concentrated near the surface of a material, so it may well be possible to use an abrasive polish to repair the PET by removing the surface layer if it does start to yellow under UV. An experiment to try, if I ever need to Smile

All very true, but those effects tend to cause sudden failure, whereas the FAQ seemed to be implying gradual failure over time. The gradual failure aspect was the thing that piqued my curiosity.

Interested.

 

Is there a review available around? I'm interested if it has autocoding for output, if it reaches 2 or 2+Amp on a single output, and if it has autorestart if sun recovers after a situation of overcast.

 

Years ago mjlorton tested all these functions and compared them for various model  in a pretty controlled enviroment in a youtube video.

It is a brand new product. Review should be available a few weeks after sale starts.

According to their FAQ no.7. 

When moving the BW-L3 from shade to sunlight, you need to reinitiate charging by disconnecting and reconnecting the device. If the device is not disconnected and reconnected, it can take up to 10 minutes for the BW-L3 to resume charging the device. The exception to this procedure is the iPhone; you do not need to reinitiate, it will quickly resume charging when moved back into the sunlight.

I hope that too….previously  I was mainly interested in the 3panel version… Because of portability (I have to use it while moving /hiking and it has to stay tied to my Dragon egg mkII backpack). I already targeted the 3panel at about 25-28 usd few days ago. But when I saw this and thought about the overcast performances that could be better than its little brother I thought I could maybe think of a compromise with size, or maybe it could work with one panel folded… Don’t know… So in summary I really hope it will be a great deal  Lol

It’s a bit too costly for me at that price. It was going to be my first foray into solar chargers and isn’t something that I really need so I’m going to pass. Thanks for organizing this though.

Freeme please explain, see a price going up when less are ordered? so if less then 100 are doing a pre order, do the people that have made the pre order need to pay extra? Or is it low price for the first 100 and then a little more for the next? argh, dont get it.

From the product detail section of the page:

Preorder Discount Before 1200 Orders
$49.98       1-100 orders
$52.98   101-400 orders
$57.98   401-800 orders
$63.98   801-1200 orders

I interpret it as the first 100 pre-orders get it at 49.98, then pre-orders 101-400 have to pay a few extra dollars at 52.98, pre-orders 401-800 pay a little more, etc. Cheaper prices for the earliest pre-orders. Entices people to pre-order early to get the best price. Classic “early bird gets the worm” marketing strategy.

From what i observed from the past 3yrs+, please take note that it may or may not happen to all deals ...

Scenario #1 - if pre-order sale is good, they will continue to run it till the specified date or quantity.  

Scenario #2 - if there is a lack of demand for pre-order after running for couple weeks, they will terminate pre-order and it will be sold in full price, partial discount or coupon deal. Product will be put it up for Flash Sale status during special events at close to pre-order rates.

 

We went through several round of discussions before we arrived at $49.98. Price was derived from our initial interest from this thread. I believe this is already the rock bottom for this new product. Like all products, it will only fall under $49.98 when there is a replacement product or model turns obsolete later.

 

From what i was told, 4 panel version was capable to produce 28W in lab, whereas 3 panel rated at 20W only max out at 18W. Package is about 0.8kg/ 1.76 pounds, we all know that international shipping fee is not going to be cheap.
