BlitzWolf 20W Solar Panel Charger review

We’ve recently reviewed two well done wall chargers from BlitzWolf. Fortunately, the manufacturer also has you covered if you don’t have a power outlet available. While smartphone batteries have gotten better, they’re still not that good. External power banks are still valuable.

Today, we have a unique approach to a portable charger – which is powered by the sun. Let me introduce the BlitzWolf 20W solar panel charger.


No, it’s not the smallest portable charger, but you don’t have to worry about charging it. And it works surprisingly well! Let’s check it out.


The design of the BlitzWolf solar panel charger is pretty simplistic. It’s foldable, because the size of the unit when fully opened would be too unwieldy to carry around.



That’s just a necessary evil, in order for the solar power to be effective. There is a crease between each panel. This gives the unit the flexibility to be propped up in different orientations or folded to a more compact size. The size of a panel is roughly the size of a sheet of printer paper.

The charger is made out of a woven fabric, similar to what you find for backpack straps. That means that it feel very sturdy. The solar panels are protected by a plastic film.


The most right panel is a pocket that has the two charging ports and space for small accessories, such as the necessary microUSB cables (one 6″ cable is supplied). The flap is secured by a strip of Velcro.



The charging ports use Power3S technology. BlitzWolf says that the charger’s 20W power capability allows the ports to output a maximum current of 3A. That’s the Quick/Fast Charging rate, so it’s pretty impressive. The unit intelligently identifies the connected device and outputs the appropriate power.


But how well does it work in practice? With one device connected and in full sunlight, I got a good charging rate; faster than standard, but not Quick Charging fast. And of course with two devices connected, the rate dropped down a bit. It then seemed more like your standard charging rate.

Final Thoughts

The BlitzWolf solar charger is a great option if you’re often outdoors. You could strap it to your backpack while hiking or lay it out while camping. No more charging up multiple battery packs to make sure that you’re covered. Sure, it’s larger than normal battery packs, and the charging rate varies, but it’s cool to have portable power supplied by the sun.
