Is it ok to use this charger for my electronics

[AlexStarr]

I am planning to buy a charger for most of my electronic (phones:Z fold 3, laptop: lenovo legion 5 pro and tablet: galaxy tab s7+)

I saw this charger that is a ugreen 100w charger is it safe for my phone which charges at 25 watt max will the battery explode due to over wattage

No it will not explode, it will be fine. The phones/laptops/tablets and the charger do a simple handshake every time and they ask the charger for however many volts/amps they need. Just if you plan to charge your laptop through USB C make sure you buy a cable that actually supports 100W charging, many of them do not.

What would happen if my cable doesn't support till 100w

I see a wording problem causing confusion.

 

The actual charger is in the phone (or in an electric car) and is smart enough to know the battery, it's state, temperature etc. Based on that it controls voltage and current going into the battery.

 

What OP looked at is the power supply that provides 5V, 12V or whatever DC as opposed to the 120 or 230 V AC. That PS knows nothing about the battery or device. The only smart part is to coordinate with the phone what voltage and current based on what standard to deliver. The phone built in charger takes it from there.

 

If you have a 12V car battery charger for a regular ICE car, that device actually is powersupply and smart charger in one. The good ones anyway. It gets connected to the battery directly and doesn't use the car's alternator"s charging controller. But this is unlike most electrical devices.

it would get hot, and then melt, and possibly catch on fire. but that is if the device is also drawing more than the cable can support.

Off-topic discussion has been split to its own discussion.

As long as the voltage is the same, the current can be higher (but not lower for proper functionality). The devices will only draw as much as they can draw, no more. As such, don't worry about the power draw of your device vs the power output of the device. It's not like it's outputting 100W to everything all the time.
It's why you can plug a lamp to the wall, that's 120V and can draw 0.5A even though the circuit breaker is 15A.

Nothing had will happen, devices only draw hads much power as they need, not the entirety of what the charger can supply.

100w means it can deliver up to it.

I finally ended up getting the charger but its just a 65w when i charger my phone z fold 3 using the 45w type c port its started making this hissing noise but when i charge my laptop with it its fine

Is this normal

I tried it on the tab s7+ no noise just phone makes noise

Merged to original. We don't allow more than one thread per subject.
