Power Cables

Power cables, as the name implies, are used to carry electricity. Whether they are adapters, chargers or extension cords, each has its own specifics that are important to consider when buying a cable. Read on to learn how to choose the right power cable.

Power Cables

Depending on their voltage and connector plug, power cords can be used to charge phones, tablets, and laptops. These are not only chargers; power cables also supply power to computer power supply components and they include all kinds of adapters and extenders.

i

If your phone can be powered by USB Type C, it is better to use a cable with this particular connector and not just an old one with an adapter.

Voltage, Wattage, and Amperage

When purchasing a new laptop charger, you have to comply with a number of parameters. If you use a cable with the wrong voltage, you risk seriously damaging the device. Too low a current will slow down charging and wrong wattage may, once again, damage the device. Do you have more than one value on the label? Get a stronger adapter to charge your laptop faster.

  • Voltage (V) - must be the same as the voltage indicated on the laptop. The most common value is 230V.
  • Amperage (A) - determines the charging speed, but the value should still be within the range indicated on the laptop parameter label.
  • Wattage (W) - this is a multiple of the output voltage and output amperage of the adapter. The wattage should ideally be the same as in the original adapter.

Laptop Adapters

If you need to buy a new laptop charger, of course, it’s best to look for original accessories first. The manufacturer usually uses the same charger cable connector for all its devices, so the only thing you have to worry about is the voltage. You will usually find the required value both on the old charger and on the bottom of the laptop or in its technical specifications.

  • Easy to get
  • It's important to pay attention to the parameters

Phone and Tablet Chargers

Since phones and tablets require significantly less voltage, there is no need for the manufacturer to develop special chargers. Today, each phone is equipped with either a USB or Lightning connector, which in addition to data transfer also delivers power.

Micro USB

  • Stable charging with cheap, easily available cables
  • Slower charging compared to modern cables

USB-C

  • Latest technology
  • Fast charging
  • Less widespread for now

Lightning

  • Fast charging
  • Apple devices only

Power Cords for PC PSUs

Your computer needs its PSU to function properly. Any failure of this component may result in damage to other components or loss of stored data. It is therefore recommended that you don’t penny-pinch when choosing the PSU or the power cord, because they are really quite crucial. A good cable should be long enough, flexible, and completely insulated.
