Likes: multiple outlets, ability to mount directly on wall or via a wall adapter. Dislikes: no case.Even though there are a lot of pieces with this charger, it works great and has a lot of utility. I highly recommend it.We got this right before an international trip, to Australia, and I am so glad I brought this and didn't use the multiple jack of all trades master of none multi multi adapters which don't stay in or keep the plugs into them. This just works! I always used to bring an extension cord plus multiple adapters for my many devices, but if this extension size works for you you can get 3 USB A ("regular"), 1 USB-C PD (Power Delivery), & 2 North American electrical plugs for laptop chargers, etc! Really happy! Look forward to trying it in additional countries and I can use it here in the US too with the included adapter!!!Model WPS-4BFrom label on back of the unit"Input: 100-250V- 50/60Hz 15A 1875W Max Output 1: 5 V DC 2.1A 10.5 WOutput 2: PD 5V 3A/9V 2A/12V 1.5A 18W"*** From instructions: "Technical SpecificationsModel No.: WPS-4BUSB power output: 5VDC, 3.1A (Total)USB Type C (PD) output: 5V/3A, 9V/2A, 12V/1.5A 18W Max • PCB with Over Heating, Current, Short Circuit protectionAC Input power: 100-240VAC, 50/60Hz, 10A"I bought this to travel to Europe with. Overall, the device appears to be well made. OREI is the only adapter company I trust.The usb-a ports share 3 amps, whereas a high speed charger would dedicate >2 amps to each port. The usb-c port has 18w, which will give fairly high speed charge to your device. I would simply use one device on the usb-a port, and another on the usb-c. Then of course you can plug more chargers into the two power sockets.The cord is about 3ft long, but the provided socket adapters can be plugged straight into the back of the OREI travel adapter and you can avoid using the cord.Keep in mind, this is not a power converter. Do not take this to Europe and use your north american hair dryer/curling iron etc. Make sure whatever you plug in can use the voltage in that country.We used it in UK and France with no issues so far. Used all the ports at the same time to charge iPhons and iPads and all worked well. Unit did not get too hot either.I like:1. flexibility of making it an extension cord instead of just a wall unit.2. Solid built.3. Like the interchangeable feature a lot.4. Small footprint. Don't take up too much space in your luggage.Dont like:1. Provided carry bag is too small. Not a deal breaker though. I used an empty headphone case instead.Over all very happy with it.So far so good, made living in Europe for six months a lot more manageable. For everyday travel will need to find a slightly larger bag so the cord fits too.Purchased this right before a trip overseas, and I'm very glad I did! The removable extension cord made it very handy regardless of where an outlet was located. We used the USB ports the most, but having actual plugs was an extra bonus. The only downside is being a bit bulky, but being smaller would have limited its usefulness.Simple, complete and convenient. Older cruise ship has limited electrical outlets. This provides all the parts needed to use one European outlet to provide 3 USB and 2 USA-comparable outlets.Bought two more for family members
