The predecessor with the 15W power had approximately halved, if you had two appliances plugged. This helps a socket to a compromise solution, with only short residence and loading times in the outlet close or simultaneous use of USB devices, however, was even more desirable. Lo and behold, 2 x 2.1 A.
Compared to its predecessor, the plug socket is slightly shorter. Thus, the power supply is seated firmly in the socket. Whether it internationally then just goes well, I have not tried it yet - other charging power supplies have also no longer base and work. Only at the campsite if you want to insert the part in the end of IP44 cable, the predecessor could be more helpful.
The body is very similar to its predecessor, but also a little wider. He Schreiter so in its width the outlet diameter - the predecessor remained almost within the circle. However, I can think of no so close to each other mounted sockets, so all good.
During long-term use in soil or distribution outlets, the USB jacks dust from the top exposed. Many other adapters have the USB ports on the side. However, I found that just good, because especially in the case of a given socket shortage this variant is very likely always accessible.
The combination of equipment designs with merciless power is m. E. is currently fairly without alternatives.
I buy the next generation ;-)
