If you buy
one after-market charger this year, it should be the Moshi ProGeo USB-C 65W charger
Why? The Moshi ProGeo USB-C 65W charger also supports the advanced PD 3.0 charging profile. PD 3.0 is 5V up to 20V and 3A to 5A (15-100W). It is a more elegant and universal solution because it allows micro-voltage and amperage steps instead of the fixed voltages. In this way, it can deliver higher voltages and lower amperages. If you want to read more about USB-C and PD, our Guide for Dummies is here.
We recommend the Moshi ProGeo USB-C 65W charger because any USB-C device to 65W (smartphones to most 13” laptops and tablets) can use it. It has comprehensive Short Circuit/Over voltage/Over current/Over temperature protection as well as the complex circuitry for PD 3.0 to better look after your battery.
It looks very well built, but there is one main advantage
over other chargers – all the PD 3.0 Electronics are in a ‘dongle’ about 125mm
from the end of the cable. It also has a smart LED indicator light there to
show charging or standby.
Separating out the electronics (intelligent regulator) from
the charger body or the USB-C tip is smart as it removes heat from those areas.
It is also compact and light at 8.8 x 5.4 x 2.5 cm x 213g
(includes long 2m cable, charger and regulator). As it is narrow, it fits standard
dual side-by-side power sockets.
You can purchase an international power adaptor pack.
Voltage regulation – EXCEED
Under PD 3.0, voltage and amperage are regulated to provide the right balance to the battery. Initially it will negotiate 20V/3.25A (65W) and if the battery accepts that it will fast charge to a pre-determined level dropping amperage first (that is the killer) and voltage last.
