Use coupon code ae9853 for massive 46% discount (-$16.91 for steel version). Brass one is under restocking at the time of posting and should arrive in few days.
It’s now in flash sale for only $37.29. This is the lowest price to date! (even lower than recent mid season snap-up where the price was $39.99 for only 15 or so pieces). Deal ends in 5 days and 12.5 hours.
This is the most powerful solar charger in Blitzwolf range. It’s capable of delivering up to 3.8A of current (it full sun) which is enough to charge at full speed 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 and quality is very good.
At the moment the most cost effective version (in $ per Watt) is still 2A BW-L2 15W for $17.99 - see here: 15W version deal
