Will this power supply work for my device?

Click For Summary

Discussion Overview

The discussion revolves around whether a new power supply will work safely for a mini-fridge after the original power adapter failed. Participants explore the specifications of the new adapter compared to the original and consider the implications of using a lower-rated power supply.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • The original power adapter specifications include an output of 12V DC at 5000 mA, while the new adapter provides 12V at 2A and 5V at 2A.
  • Some participants inquire about the electric power consumption of the fridge to assess compatibility.
  • One participant expresses doubt that a 2A supply would be sufficient, especially considering potential startup surges that could exceed 2A.
  • Another suggests using a 2 amp fuse in line to protect the new power supply from potential overloads.
  • Concerns are raised about the adequacy of 24 watts to run any refrigerator, implying that it may not be sufficient.
  • A participant mentions that replacing the power supply might be costly relative to purchasing a new mini-fridge.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the new power supply is safe or adequate for the mini-fridge. There are competing views regarding the sufficiency of the 2A rating and the potential risks involved.

Contextual Notes

Participants note the lack of specific information about the fridge's power consumption and manufacturer, which complicates the assessment of the new power supply's suitability.

Will this power supply work for my device? URGENT!

I have a Mini-fridge I need to get usable again. Recently, as of a few minutes ago, I opened up its power adapter to find that capacitors have burst and that would be the reason of the fridges death a few months ago.
Given the mini-fridge is literally a foot or so tall.. keep that in mind. these are the original specs of the adapter

Original:
INPUT: 120V AC 60hz 1.2A
OUTPUT: 12V DC 5000 mA Max

Now, i have the new adapter that I spliced with the old connection (I'm sure this will work, done things before, end is pretty simple, trust me)

INPUT: 100-250V AC 50/60Hz, 0.5A
OUTPUT: 12v 2A
5V 2ASo all and all, will this work?

Oh, might I add, the adapter currently works on the fridge..But, Is it safe? Does it all sound accurate?

What's the electric power consumption listed on the fridge?
 


The fridge is small, and more or less has no information on it all all.
 


Could you at least provide the manufacturer and/or model so we can look up specs online?
 


If it blew a 5A supply I doubt a 2A supply will last long. Even if it does not draw 2A during operation there could be start up surges much higher.

I would not recommend using the 2A supply.
 


Haha, I would most definitely love to post up the manufacturer. But It is so offbrand or something odd, that I can't even give that. I got this from a friend about a year ago, and it finally died a month ago..
 


Then, this:

You could put a 2 amp fuse in line to make sure you don't blow up the new power supply and possibly cause a fire.
If that blows, the power supply was in danger.

24 watts doesn't sound like enough to run any kind of refrigerator.
 


I was looking on ebay recently and mini fridges aren't that pricey. A replacement PSU may well be a substantial fraction of the cost of a whole new setup.
And cold beer / coke is verrry important.
