This review is for the Lumsing 4-Port 21W Family-sized USB Wall Charger.
I like this charger because of its small form factor and multiple USB ports.
The plug prongs fold flush to the brick, making it even more portable.
Each of the four USB ports are optimized for different output rates, depending on the device you are charging.
The unit has over-voltage, over-current, short circuit and over-temperature protection to ensure safe use.
The fact that it has four ports gave me the ability to charge four devices simultaneously, which worked well.
The charger grips well in the hand thanks to its small size and non slip textured paint. Build quality is excellent for such a charger.
I was sent this product for evaluation at a discounted price for my honest opinion.
