Review on Topsolar SolarFairy 30S Foldable Solar Panel 30W Portable Battery Charger Kit for Cell Phone Power Bank Car Boat RVs Off-Grid Charging of 12V Batteries & 5V Devices by Ryan Saxton

I have 16-17w on a pair of jacker power stations so not impressive. But at least it has a DC output to power them (with the 8mm adapter not included) which many of these little chargers don't have. It comes with plenty of ports and cables, which again is good but has limited uses. I think you can slowly charge a 12V battery directly. Most people are probably buying this for cell phones or batteries, in which case some sort of pouch would be useful. The last big blue one is better in this regard (has a nice case with the same thin magnetic design) but no DC output. I would probably go for the big blue for direct phone or power bank charging and for power stations a 60w or 120w TP solar briefcase. On the other hand, these portfolio panels are much larger. This could be a great compact phone or power bank charger with capability, like a Jackery 160 or similar small power station in a pinch.
