Why do laptops need a transformer when plugged in?
The “Transformer” converts the AC power to DC at the required voltage (there is a rectification circuit incorporated also). Your laptop is designed to run and charge at a certain voltage in DC power supply. House hold power is at a different(higher) voltage than what your laptop uses in AC power supply.
How many joules of surge protection do I need for a laptop?
If you’re trying to protect things like cell phones, basic laptops, printers, routers, and copiers, you’ll want a surge protector with a rating between 1,000 and 2,000 joules. This rating is also large enough for your power tools and other building appliances.
Are computers surge protected?
The short answer is no, power strips do not protect your PC from any sort of electrical fluctuations. Many people assume that all power bars have surge protection but unless it is specified, you’re components will be left unprotected.
Do Apple laptops need surge protectors?
Buy a Surge Protector or UPS You may be tempted to plug your Mac directly into a wall outlet. Don’t. You need at least a quality surge protector, which acts as a sort of electrical firewall, protecting against destructive power incidents. (See How Surge Protectors Work for tips on finding a good one.)
How do I protect my computer from High voltage?
How to Protect Your Computer From Power Surges

Are charging blocks transformers?
Yes, they still have a transformer inside. That’s necessary, otherwise the low-voltage side wouldn’t be touch-safe. The transformer is kept very small. That’s possible because it works at a very high frequency; the mains voltage is rectified and a high-frequency switcher feeds the transformer.
Why does my laptop need a transformer to charge?
Your laptop is designed to run and charge at a certain voltage in DC power supply. House hold power is at a different (higher) voltage than what your laptop uses in AC power supply. The “Transformer” converts the AC power to DC at the required voltage (there is a rectification circuit incorporated also).
Do laptops need surge protectors?
He said laptops don’t need surge protectors because their power bricks protect the machine from power surges. That just didn’t sound right to me, but I’m not one to argue. Was he right or do I need to go ahead and buy a surge protector for my son’s new laptop?
Can a power brick take out a laptop?
A strong surge or lightning strike can easily take out the power brick itself, and the laptop along with it if the surge is strong enough. As a general rule, anything that plugs into a wall outlet can be destroyed by a power surge or lightning strike.
What is the function of a power converter in a laptop?
The “Transformer” converts the AC power to DC at the required voltage (there is a rectification circuit incorporated also). The power converter for your laptop delivers a higher current to your laptop than it receives from the AC supply. This is because the Power used in the transaction is the same (ignoring negligible losses). An example:
