A dead laptop charger or patchy Wi-Fi can stall a whole workday. Our Computer collection is packed with practical fixes: replacement MacBook chargers in 45W, 60W and 85W MagSafe and MagSafe 2 styles plus 61W USB-C, universal laptop chargers, Surface Pro power adapters, Wi-Fi repeaters and dual-band USB Wi-Fi adapters, and long ethernet LAN cables in 15, 20 and 30 metre lengths.
For connecting screens and older gear there are RCA-to-HDMI and HDMI-to-RCA converters, USB-to-HDMI adapters, DisplayPort and DVI cables, HDMI capture cards for streaming, and optical-to-RCA audio converters. You'll also find external CD/DVD writers, compatible Brother toner and ink cartridges, gaming keyboard and mouse sets, 10.1-inch Android tablets, laser engravers and a range of computer and RGB gaming desks. It suits home offices, students, small businesses and anyone keeping older devices running.
Stock ships from New Zealand, so you can replace a charger or cable quickly and get back online. Related ranges include laptop chargers and accessories, desks and computer tables and office and desk chairs.
How to Choose the Right Computer
- Charger wattage: Match or exceed your laptop's original charger wattage and check the connector: MagSafe, MagSafe 2 or USB-C.
- Wired or wireless: An ethernet cable gives the steadiest connection for gaming and video calls; a Wi-Fi repeater helps where cables can't reach.
- Video adapters: Check which direction a converter works – RCA to HDMI is not the same as HDMI to RCA – and whether it needs USB power.
- Printer supplies: Confirm your printer model against the cartridge code, such as TN1070 or LC233, before ordering.
- Desk size: Measure your space and allow room for monitors and a keyboard; around 120cm suits one screen, while 140cm gives more room for two.
- Optical drives: External USB DVD writers suit laptops without a disc drive, for installing software or copying old CDs and DVDs.

Computer FAQs
Can I use a higher wattage charger on my MacBook?
Generally yes. A laptop only draws the power it needs, so a charger with equal or higher wattage and the correct connector is fine to use. A lower wattage charger may charge slowly or fail to keep up during heavy use. Always match the connector type, whether MagSafe, MagSafe 2 or USB-C.
Does a Wi-Fi repeater slow down internet?
A repeater rebroadcasts your router's signal into dead zones, which can lower top speeds compared with sitting next to the router. For most browsing and streaming, the better coverage outweighs that trade-off. Place the repeater roughly halfway between the router and the weak spot, where the original signal is still reasonably strong.
How long can an ethernet cable be?
Standard ethernet cabling can run up to around 100 metres before signal quality drops, so 15, 20 and 30 metre cables are well within range for homes and offices. Keep cables away from power lines where possible, avoid tight kinks, and use clips to run them neatly along skirting boards.
How do I connect an old VCR or console to a modern TV?
Older devices with red, white and yellow RCA outputs can connect to an HDMI-only TV through an RCA-to-HDMI converter. Plug the RCA cables into the converter, run HDMI to the TV and power the converter via USB. Picture quality will match the original source, so don't expect high definition.
How long does delivery of computer take?
Processing takes 1–2 working days, and orders placed before 12PM on a working day leave our warehouse the same day. Delivery then takes 2–4 working days to non-rural addresses, with an extra 1–2 working days for rural delivery addresses. Shipping details
