About chargers & power banks
Chargers and power gear include power banks, car and wall chargers, charging cables, power strips and wireless pads.
Car chargers range from dual port 20 W models to a 45 W unit and multi-port versions with five or six outputs, plus a 4-in-1 retractable cable. For home, there are 3-port USB wall chargers, corner power strips and 4 or 5 outlet socket adapters. A 20000 mAh laptop power bank offers 100 W. A wireless charger doubles as an alarm clock.
Match plug and wattage to your device. Laptops need higher watts than phones, and USB-C ports usually give faster charging. A 6 A cable can carry more power, so it suits fast charging. Check the plug style of wall adapters, because they are made for specific sockets. Retractable cables cut tangles.
Chargers & Power Banks questions
How many watts do I need to charge a laptop?
Many laptops need 45 to 100 W, so check the power label on your current charger. A 100 W USB-C power bank can charge many laptops, while phones need much less.
Is a fast charging cable different from a normal one?
Yes. Cables rated for higher current, such as 6 A, can carry more power. Use one with a charger that supports fast charging, or the speed will stay the same.
What does mAh mean on a power bank?
It shows battery capacity. A 20000 mAh bank can charge a phone several times. Real output is lower than the label because of conversion losses.
