Selecting a replacement external power supply – what you need …
In replacing the power supply in Figure 1, getting a power supply that delivers over 3.34A by half an amp is still safe. (Keep it to 20% over at most, because the power supply you''re replacing is likely already oversized by 25 – 30%.) Think of electricity as a hose. The flow coming out is current, and the voltage is the available pressure ...
