✴️ Power supply labels can be difficult to read and interpret. I'll review what matters.
✴️ Reading phone-charger specs
Chargers usually have tiny, hard-to-read specifications. Input power details the voltage and frequency compatibility with your wall power, while output power indicates the voltage and current supply available to the device being powered. Some chargers offer multiple outputs for different devices, adapting voltage as needed.

Hard to see and confusing.

The USB Power Delivery(PD 3.0 and newer) standard is a godsend, but there's always the transition period until everything you have is compatible. And it still makes sense for low power devices to stick with ye-olde 5V 0.5A standard, as the components are inexpensive and relatively rugged.

Really love your YT videos. You should have millions of subscribers. Hopefully one day in the not so distant future you will.

Hello sir, i am a big fan of your explanation. i have seen your video about Microsoft windows user account and local account. At present i am using Microsoft windows user account instead of local account. now i want to change my sign in option for Microsoft user account. instead of pin i need password. because i have problem in SQL server reporting services due to this pin. i already use include letters and symbols option. but no use. can i change that sign in option? please explain sir.

More good stuff Leo. Dumb question. How do I know if my "device" is smart or dumb? JimE

Usually you'll have to look at the devices documentation. But if it has a "fast' charging mode when connected to some chargers, then it's likely to be smart.

Funny, my galaxy phone manual says I am to use only the samsung-approved charging block, yet the company has none in stock. The phone came only with a USB3 type C cable. I ended up using the chromebook charger, which supposedly voids the warranty.

Yeah, while using the manufacturer's device is the best option, it's not the only option. And requiring it is just the manufacturer covering their behinds in case you use a crappy alternative that damages your phone.

It's just funny, 'cause even if you want to "follow the rules exactly" you can't. Then there's the other phenomena: if apple corporation takes out the charging block / headphone jack / transflash socket, other manufacturers copy the behavior. I know of few other instances this happens.

There is a bit of gray area when it comes to amperage. In case point if your charger delivers 2A but your device can only accept 1A, then that could be an issue depending on your device. You could essentially get too much amperage being delivered to the device which it can harm device. Again it all depends on what type of device you are charging. If you are charging a dumb device with no intelligent capabilities, you want to stick to a charger that matches the required input. The exception of course as you explained is most devices have intelligent charging capabilities, cell phones etc. So if you have an old device that requires 5v @ 500mA, stick with a charger that will deliver the same. You could use a 5v 450mA (it will just take longer), you just can't use 5v @ 1A. The amperage is too high. In theory as you stated with a smart device that is rated @ 2A you could use a 3A, because the smart device will regulate the power required. Unless something fails of course.

"You could essentially get too much amperage being delivered to the device which it can harm device. " This is very rarely the case -- only for VERY poorly designed devices. A device that needs 1A should only ever take 1A, regardless of the rating of the power supply being higher.
