This category covers laptop chargers, power adapters and replacement laptop batteries, for anyone whose original charger has failed, whose battery no longer lasts a working day, or who wants a spare set for the office or travel. Our range has over 12,000 products, including Dell, Lenovo, HP, ASUS and Acer items as well as compatible chargers and batteries from 2-Power and Green Cell.
How to choose a laptop charger or battery
Exact model. Batteries are made for specific laptops, so check the full model name on the underside of the laptop or the part number printed on the old battery. A battery that looks similar can have a different connector or cell layout.
Wattage and voltage. The charger's wattage and output voltage should match those printed on the original. A higher-wattage adapter with the same voltage usually works, while a weaker one may charge very slowly or fail to keep up when the laptop is under heavy load.
USB-C or barrel plug. Many newer laptops charge over USB-C with Power Delivery, but a USB-C port alone does not mean any USB-C charger will do: it must deliver enough wattage. Older Dell, Lenovo and HP laptops use barrel plugs, and the diameter and pin arrangement vary.
Capacity and cells. Battery capacity is given in Wh or mAh, often alongside the number of cells. Higher capacity means longer time away from a socket, but the battery must still physically fit your model and have the same voltage.
Original or compatible. Original parts match the manufacturer's specification exactly. Compatible batteries and chargers are often cheaper, but check for protection against overcharging and short circuits, and for CE marking.
Brands we carry
- Dell: many of its laptops identify the adapter through a data pin in the barrel plug, so a wrong charger can trigger a warning or limit charging.
- Lenovo: chargers and batteries for ThinkPad and IdeaPad lines; newer models often charge over USB-C, while older ones use a rectangular plug.
- HP: original chargers and batteries for the EliteBook, ProBook and Pavilion lines, including older models with barrel plugs.
- ASUS and Acer: adapters and batteries for everyday and gaming laptops; ASUS gaming models often need a high-wattage charger.
- Green Cell: a Polish manufacturer of replacement batteries and chargers for many laptop brands.
Also in our range: 2-Power, CoreParts, Origin Storage and Mitsu.
Frequently asked questions
How do I find out which charger fits my laptop?
Look at the label on the original charger, which gives the voltage, current and wattage. A new charger should match the voltage, use the same plug and offer at least the same wattage. If the label is missing, search by the laptop's model name.
Can I use a higher-wattage charger?
Yes, as long as the voltage and plug match, a higher-wattage charger normally works. The laptop only draws the current it needs. A lower-wattage charger is not recommended, as it may overheat or fail to keep up with charging.
Can any USB-C charger charge a laptop?
No, the laptop must support charging over USB-C and the charger must supply enough power. A phone charger is usually too weak, so the laptop would charge very slowly or not at all. Check that the charger lists Power Delivery and the wattage your laptop needs.
When should a laptop battery be replaced?
Replace it when the run time drops sharply, the laptop shuts down while still showing charge, or the battery starts to swell. Stop using a swollen battery straight away. Choose the new one by the exact model or part number.
