I’ve been looking closely at folding, portable solar USB chargers over the past few days. From what I can tell, units with these high-efficiency SunPower cells go for ~$2 or more per nameplate watt delivered to the US. So, $50, or $52.98, for a 28W unit is likely as good as it’ll get any time soon.
I ended up finding a 21w 3/panel on Amazon for ~$36 with same day delivery, so I snapped it up and wrote the first review. I only gave it three stars because the product description was self-contradictory and didn’t quite match what I received, but near as I can tell, it performs like most of the other products in its class that people reviewed. With good sun, good orientation, and no shadowing I could pull ~10W in the early afternoon using an adjustable load. Later in the afternoon, I could charge two USB powerbanks — a Jackery ThunderX 20,000 mAh and a thin Xiaomi 5,000 mAh at about 2.4A combined, though I think it may have been capable of more.
Anyway, $52.99 for these BW-PW3 look like a good deal.
According to BlitzWolf site: ...If the device is not disconnected and reconnected, it can take up to 10 minutes for the BW-L3 to resume charging the device...

First post indicates $47.50 but Banggood site indicates $81.99. I thought I read there was no coupon code for this. That it was a group Buy without coupon code.
They tried to rush to launch during BG Anniversary period, but the design was not ready for mass production unfortunately. After 2 months of further testing and new material acquisition, they have finally announced that BW-L3 is ready to be released. By the way, $49.98 was pre-order price (closed) for public.

Sorry grammarlovers, I am a real King Typo.
Not interested at $50, sorry.
Beam me up!
Ordered one. 49,98 $ for 28 w isnt that bad.
Thanks
A 4-panel, 28W charger for less than the price of a 3-panel, ~20W charger looks tempting. I’m interested.
Hopefully, that extra output will allow this one to provide a useful charging rate for a single device under sub-optimal light.
Over hundred pieces pre-ordered.

$92.99 (original price) and $81.99 are both ridiculously inflated. Wasn’t Bangood’s regular price closer to $55? Lame.
