This is the nicest charger that I own.Look at my first picture. It is the case that the charger comes in. When you see something like this you know it is something special. The second picture shows the zippered case opened. It contains the charger (it has foldable plug so it takes up less room when traveling), usb-c to usb-c charger cord in the top of the case and the spec sheet unfolded to show that it also comes with a LIFETIME WARRANTY!This charger has a 40W maximum to share between two USB-C outputs. You can charge one device up to 40W or share the 40W between two devices at the same time. There is a little indicator light so you know the power is on and the charger is ready to go. The charger has GaN and PPS (more on why this is important below).Why choose GaN and PPS?There are two things to look for if you want a higher quality charger. You want to have "GaN" and "PPS".GaN is a technology (a new type of semiconductor material) which to the user means that the charger can be smaller and is more efficient (waste less electricity). You can see the size difference by looking at the third picture I have provided. The Maninam charger is on the left side of the power strip. To its right is the Apple 5W charger and to the right of that is the Apple 10W charger and to the right of that is the Apple 20W charger (note it is not plugged in and standing on its plug pins because it takes 2 slots and only 1 was left). The Maninam is smaller than the Apple 12W charger but provides a maximum of 40 W. Because it has more power it CAN charge your device faster. It is important to understand that the wattage specified by the charger is only the maximum it can supply. This doesn't guarantee that older devices will take advantage of it and charge faster.PPS (programmable power supply) is a protocol/specification. If your device supports PPS it also supports PD (another older protocol) but not all PD chargers support PPS so it must state that it supports PPS. PPS allows your device to talk (renegotiate) to the charger and request non-standard currents and voltages. This means that there will be a lower conversion loss during charging. To the user this means that less heat will be generated (in the battery being charged) which can lengthen the battery lifespan.If possible you should always look for Gan and PPS in the charger specifications.
