The idea was originally to review this for AAWP (see link, right), but having examined and tried this neat little Tronsmart gadget, it seems too Quick Charge 3.0-centric for the world of Windows Phone and Windows 10 Mobile, where 'fast charging' refers to the USB Type C 'Power Delivery' system, i.e. 5V at high current (up to 4A in some cases, but more usually 3A max).
It's true that this Tronsmart Dual Quick Charge 3.0 36W wall charger also outputs up to 2.4A at 5V, so that it's technically compatible with Microsoft Lumias, Google Pixels, Apple iPads, and so on, the majority of the world which doesn't use Quick Charge 2.0 or 3.0. But it's not optimised as such, so the USP here wouldn't be appreciated by users of any of these devices - plus their original 3A chargers would give a faster charge.
However, many of us have multiple device these days, certainly around a family, so a mix of 2015/2016 phones with both 'Power Delivery' and Quick Charge requirements. In which case this gadget is perfect - just plug in any USB cable and let the wall charger work out what voltage to supply and at what current.
The gadget is black, solid and unobtrusive - both ports have the trademark Quick Charge coloured blades and both can supply the same voltage/current combinations - at the same time, hence the overall 36W rating.
There's a green status LED on the top, which lights to let you know that power is being delivered. This is the UK variant, though two pin mains versions are available for other markets.
My only worry is that the charger sticks out quite a way, so you might want to make sure it's not easily knocked or tripped over! And I'd bet that this applies even more to those International two pin variants. Then again, there's a lot of clever circuitry to pack in, and safely too, given the power rating!
At £16 currently, on offer on Amazon UK, this is good value for a trusted charger brand and it's made it's way into my go-everywhere overnight bag.
