Works as advertised

Pros: Works as description advertises. Convenient size and quality build.Cons: External shape of product "bumps out", just below outlet prongs, causing it to project out slightly from wall plate or power strip. Consequently, the plug can somewhat easily and accidentally be unplugged if bumped, or a mild tug is applied to a device attached one of the USB charging ports. Other: I would purchase this again. Works as I expected. Many, many positives despite the small issue I mentioned.

Part Number: SW-30393
Efficient for travelers

Pros: It has two USB ports with high ouput It can accommodate 4 phonesCons: It cannot charge a power bank with other devicesOther: I have bought two devices from this charger. It is excellent and efficient working. But once I put a power bank with the other phones during charging, it got smoked and burnt out. I mailed the customer service and I knew that it was my fault to do this, but they inform me that the device is under a warranty for 1 yr. They've opened an RMA for me, then replaced it for me with a new device. Now I've both of them working well, and I got more cautious about the ouput power of every USB port. Thanks Swell for your marvelous device and amazing customer service.
