Any possible downsides to use those cellphone chargers to drive small amounts of leds?

Any possible downsides to use those cellphone chargers to drive small amounts of leds? They come for cheap and are pretty convenient to use alongside a USB battery pack to make a project both portable and compatible with a wall outlet.

I’ve been researching if they should last for a long time under a constant moderate load (1A). I’m worried about long term. Any difference to a regular 2A PSU in your opinion?

Most of the cheap ones are hot garbage with inadequate protection.

@Martin_Espinoza Any recommendation on good ones?

I’ve had good luck with Anker products, like this one: https://www.amazon.com/dp/B071YMZ4LD

Yeah. What @Martin_Espinoza said.
A lot of the aftermarket ones are just a gift wrapped house fire.

As usual, Big Clive has some excellent videos on the subject:

@Jason_Coon Any thoughts on eeco and Aukey brands? The form factor on these chargers fits exactly my needs :

The Anker ones seem awesome but they are a bit big and have a powerful status led… less an option for me since I want to retrofit existing projects.

Thank you!!

I’m using a 20,100mAh power bank. 3.4A max output. Jackery Force 420 Pro. Not cheap but they do smaller, cheaper ones. Apparently “Their professional line-ups all feature nine layer protection by well-known Texas Instruments chipsets for Li-on battery temperature control, protection against short-circuit, overvoltage, overcharge, over-discharge and overcurrent.” Sounds safe.

@Franck_Marcotte I couldn’t find anything on eeco, but did find this teardown of an Aukey adapter: https://www.tomshardware.com/picturestory/815-aukey-pa-u32-usb-power-adapter-tear-down.html#s40

@Jason_Coon Great find! I ordered a bunch of different models to test including that Aukey. The teardown gives me hope, it looks solidly built for how compact it is.
