OBSERVATIONS

The heatsink keeps this little charger cooler than other chargers.  TODO Measure temp at 5V 2A out
The heatsink does get hot at 2A, so it requires some ventilation
Input current must be enough to supply phone’s requirements or the charger won’t stabilise
This supplies 9V to a powerbank I have.

Be careful with clone UK suppliers – they’re quite often drop-shippers who have no idea what they’re selling – just check their feedback.
