Looking for a good power adapter

As my server works 24/7, I spent a bit of time to find a good power supply for my Raspberry Pi

Recommendations for the Raspberry Pi are to use an 5V 700mA USB power adapter .

So I checked my stuff for what USB chargers I already had. I found several alimentions 500mA and 1000mA. They all work with my Raspberry Pi, but I feel these alimentations become too hot after a long usage.

So I started looking for a bit more powerful adapter, thinking that an over-sized power adapter should help to reduce heating and improve the life of the power adapter and of the Rasperry Pi

I found several chargers over 2000mA on the Internet, some with two USB ports, like this one, brand Bluestork:

Others with 1 USB port, like this one, brand Re-volt:

I have a preference for a model with one USB port, as some 2000mA models with 2 USB ports are in fact 2 x 1000mA

But ultimately, I chose this one, brand Apple:
€ 19.99 is a bit expensive for a power adapter, but it fits in the budget of the project. I found it in a local shop and I therefore saved shipping cost. In addition, the brand is well known, and I think I can benefit from the guarantee in case of problems.

After 2 days of usage, I feel this one a bit less hot than my older one.

Impact on the project: -19.90€


  1. Yes, I'm looking for a good power adapter and hopefully your article assisted me to let this know that which power adapter is good for using and I'm pleased. Thanks

  2. Their project management needs improvement, Best_iPhone_Podcast_Microphone_for_General_use agency earned praise for his or her responsive communication and easygoing approach and affordable pricing.
