Backup power: say what exactly you’re looking for

Backup power in South Africa: prices and rules

Updated 4 November 2026

A UPS for a router or desktop in South Africa costs roughly R 700 to R 4,000, a portable power station about R 3,400 to R 9,900, and a home battery kit about R 17,900 to R 48,500. These are sellers' prices from November 2026. To get a quote for the load you need to back up, create a request on BlaBlaPrice.

Certificates and warranties

Insurers in South Africa reject some claims for fire and damage caused by non-compliant backup power systems, so an installed system should come with a certificate of compliance. Ask the installer for it before you pay. Warranties differ: one lithium battery maker guarantees that its battery keeps 60% of its nominal energy for ten years, and one portable power station brand warrants 80% of its output for 25 years. Generators supplied under a government tender must carry a 12-month guarantee on the installation and equipment, so ask for the same term.

Season and planning

Summer runs from December to February and winter from June to August, and November sits between them. A unit bought now is ready for both seasons. Start with the hours of backup you need: a portable station's watt-hours (Wh) show how long a load runs, while a UPS is rated in volt-amperes (VA) and shows how much it can carry for a short time.

Plugs, units and how it is bought

South African outlets take the three-pin plug, so check that an imported unit comes with a South African plug or adaptor. Power is given in watts, volt-amperes and kilowatt-hours, so ask for all three when you compare. Ask whether the price includes delivery to Johannesburg, Pretoria, Durban, Cape Town or Gqeberha, and whether VAT is included. Listings differ in what they include, so compare like with like.

What to write in your request

Say what you want to power: a router, a fridge, a laptop, lights or a whole house. Give the total load in watts, how many hours of backup you need, the number of outlets, whether the unit is for indoors or outdoors, whether you want solar charging, and your budget in rand. For an installed system, add your city and the wall or roof space available.

On BlaBlaPrice you describe your power needs in your own words in the chat, and you can add a photo of the device label.
