I just copied the original title. Must be an description error. K1 only has 2 red LED and 4 blue LED indicators:

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
I received mine some days ago. Well made product! It was a warm and bright day, although cloudy as well, so there was no direct sunlight. I got 0.3A @ ~5.15V, so it’s a slow charge for my phone, but it was charging nevertheless. Nice to test again with direct sunlight!
Any accessories that can plug into this Blitzwolf solar panel to charge 12v car battery that parked under sun?
Or use a cheap boost circuit will do? Will it spoil the car battery?
Thanks.
I am thinking if I use a boost circuit that set the voltage to let’s say 13.5V, so it won’t charge the car battery to 14+V, will it still over charge the car battery?
According to article below, it is the maintenance phase, looks like it is not charging the battery anymore.
I really don’t know. I’ve got two new charger/maintainers on motorcycles and they tend to maintain at about 12.6v to 12.8v. They have advanced circuitry like in the link you posted where it goes through multiple phases to charge, monitor and maintain the batteries.
I know there are solar chargers for 12v RV’s and boats, etc… You don’t want to get one of them? If not, I would do some online research to see if these 5v units can be rigged and not ruin your battery.
Ya, I have two car battery chargers those do multi phase charging. I think this Blitzwolf is good product and if it can be used for multi purpose besides charging mobile phones, it will be even better. That is why I am not keen on getting those 12v solar for car, and not sure how is the quality/price compared to Blitzwolf.
I’m no expert either but from what I understand I’d say this should work and will not overcharge the battery. But this will reduce charging efficiency as you would have two converters in series (Blitzwolf already has some kind of converter for 5V), charge rate would also be reduced by placing the panels behind glass window.
