At 0.5A it stabilises at 36degC after 5 minutes, dropping to 4.95V, 2.48W. It draws 0.25A from 12.7V, 3.17W = 78% efficiency.
At 1A it stabilises at 49degC after 5 minutes, dropping to 4.92V, 4.92W. It draws 0.5A from 12.6V, 6.3W = 78% efficiency.
At 2A it stabilises at 79degC after 5 minutes, dropping to 4.86V, 9.6W. It draws 1.1A from 12.5V, 13.75W = 69% efficiency.
Nice simple screw terminals for attaching input power cables. No soldering required.

I’ll post same weekday if you order before 3pm.
My support is second to none. Check my feedback. I will gladly help you before or after purchase. I love power supplies!
I’ll refund you if it’s faulty or return it working if it doesn’t perform as you expect.
Be careful with clone UK suppliers – the ones with all the same photos – they’re quite often drop-shippers who have no idea what they’re selling – just check their feedback. You won’t get any meaningful support from them.
