This category contains laptop power adapters, USB chargers and other external power supplies, for anyone who needs to replace a faulty or lost charger or keep a spare for travel. Our range includes over 70 products, among them Lenovo, Dell, StarTech.com and Akasa.
It also covers specialised power supplies for office and business equipment, so it pays to check the technical details before ordering.
How to choose a power adapter or charger
Voltage and current. The output voltage (V) printed on your old adapter must match the new one. The current (A) can be the same or higher, because the device draws only what it needs, while a weaker adapter will overheat and may not keep the device running reliably.
Wattage. A laptop needs at least the wattage (W) stated on its original adapter. A phone or tablet usually needs a few dozen watts, a thin laptop often needs around 45-65 W, and gaming or workstation models need considerably more.
Connector type. Newer laptops charge over USB-C with USB Power Delivery, so one charger can serve both a phone and a laptop. Older models use round barrel connectors of different diameters or manufacturer-specific plugs, so check the exact connector format.
Original or universal. A manufacturer's original adapter guarantees compatibility with the specific model. A universal adapter with interchangeable tips suits several devices, but you must set the voltage and polarity correctly before connecting.
Safety and convenience. Look for CE marking and protection against overheating and short circuits. If you will carry the adapter around, pay attention to cable length and the size of the casing.

Frequently asked questions
Can I charge a laptop with an adapter other than the original?
Yes, as long as the voltage and connector match and the wattage is not lower than that of the original adapter. The wrong voltage can damage the laptop. Compare the figures with the label on your old adapter before buying.
How many watts does a laptop charger need?
The wattage must be at least what the original adapter provides, otherwise the laptop will charge slowly or not at all under heavy load. A more powerful adapter with the same voltage and connector is safe, because the device draws only the current it needs.
Can one USB-C charger power both a phone and a laptop?
Yes, if the charger supports USB Power Delivery and has enough wattage for the laptop. A phone needs far less power, while a laptop often needs 45 W or more. You also need a USB-C cable rated for that power level.
How do I find out which connector my adapter needs?
The connector type is determined by the laptop model and by the label on the old adapter, which shows the voltage, current and sometimes the plug dimensions. If you no longer have the adapter, find the model number on the underside of the laptop and choose a compatible adapter from it.
