I have been having Problems with 5 volt 15 amp AC Adapters. Three of them have died in the last 2 or 3 months. I opened them up and the capacitors are blowing up. I have been looking for a solution for a while because they run too hot. I use them to power my signs and the sign is limited in brightness so it only consumes 12 amps. In fact I have powered one LED sign with a 10 Amp AC adapter for a few months with no issues other than a warm AC adapter. Recently I went on Amazon instead of eBay and found a better 5 volt AC adapter! Here is the ad on Amazon:
The advertisement even shows the insides of the Ac adapter to show how it is built better.
