It’s now in flash sale for $50.99 ($92.99). Offer expires in 5 days and 9 hours.
This is the most powerful solar charger in Blitzwolf range. It’s capable of delivering 3.8A of current (it full sun) which is enough to charge at full speed two high power devices (high-end smartphones or tablets). Even smaller Blitzwolf panels can charge smartphones in cloudy day so this should easily power more demanding tablets. Solar cells from SunPower provide unsurpassed conversion efficiency over 23.5%
Blitzwolf chargers offer best value/cost ratio on the market at the moment and quality is very good. Lower powered BlitzWolf® 15W 2A BW-L2 and BlitzWolf® 20W 3A BW-L1 versions have much more reviews, 28W is quite recent.
Good to know. For the price I would suppose the quality control is at best “it works so it’s ok”.
I just found this review: XANES WT518 review by carambola
It seems he had more luck as what he describes is more or less what I would expect from 4$ light.
Well, agree it does work, maybe I even agree its worth $4, but comparing this with cheap convoys…difference is quite obvious in all respects I could think of
