Mobile phone charger

I've got a bunch of USB chargers and it would make sense to me to use one of them to power Espruino. Which parameters should I pay attention to if I don't want to damage anything?

I wouldn't worry too much... Espruino's got a voltage regulator on board, so as long as the voltage doesn't go above 16v you'll be fine!

Basically if you've used it on your phone and your phone still works, then it should be fine for Espruino :)

There have been problems with some chargers turning off because Espruino doesn't draw enough power to convince them anything is connected - but that won't really do anything any damage.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
