Connecting LED panel to mobile phone charger.

[kuhinja123]

Hi!
My question is, can I connect 5V LED **broken link removed** to a phonecharger **broken link removed**.

I am worried because of a amperage difference LED - 360mA and phonecharger 1A.

Any ideas?

Be more worried that the LED voltages make no sense for 3x8 array of 3V LEDs

There is extremely little in the way of details on the LED panel.

I would ASSUME it works off 5V, IF that is true, then no problem as far as voltage is concerned . I have no idea as to the current drain. It could overwhelm the "charger". It seems the "charger" is NOT a charger - it merely supplies 5V at up to 1A via USB cable.

Your "5V" cell phone charger might have an output of 5.5V. Then the no-name-brand LED module with no visible current limiting might burn out.
It will get extremely hot dissipating 1.6W and the heat might destroy it. Of course ebay does not say anything about how you will cool it.

There is that. I am active on a specialized LED board, and many of these cheap LED lights have the LEDs in parallel without proper current limiting - which WILL burn out when connected to a 'strong' power supply. Rather than seeking the cheapest panel, you might want to source a LED panel that has complete specs that meet your objectives.

The people over there who make those very cheapo LED things do not speeky zee Engrish. They do not want anybody to know that they burn out easily and do not last long.

OK, I thank all for quick answers... I see, that it is more complicated than i thought....

I will ask differently... I am woodworker and i got an idea for wooden table (reading) light project. I would like to use LEDs. So what do you suggest?

 

[kam1787]

Your idea is sound. The LED panel seemed suspect - a name brand would be a better choice or at least source from more reputable supplier .

{I noticed after my post - having looked at the link[where I could not find any specifications] you stated it was 360mA - how did you know that?]

I'd go for a 12V LED panel - more energy efficient.

Did you want more light in a small area, or a wider area. LED strips are good for a wider area.

A problem with buying electronic parts from ebay is that the parts are very cheap with poor quality and ebay knows nothing about electronics so they spec not much more than the size and weight.

Here are the spec's showing 360mA (15mA per LED if they are matched):
