Thanks for the question! Based on the search results, the Gentech 6KVA Digital Inverter Generator for R24,999 seems like a great option if you need a heavy duty machine that can power many devices for your store. However, as this is an experimental generator it may be more than you need. For a lighter duty machine, the Ryobi 1200W Inverter Generator for R5,499 or the GENTECH POWER Gentech 2KVA Inverter Generator for R8,999 could work well. Both are inverter generators which provide clean power without fluctuations. Let me know if you have any other questions!
Based on your question about an airtime vending machine, let me recommend the Omega 2000W Portable Petrol Inverter Generator for R9,199 as an affordable option to power your machine. As an inverter generator, it will run quietly and is suitable for electronic devices. Its 2000W output should be sufficient to run a standard airtime vending machine while allowing some extra power for other store needs. Please let me know if you need any other details! I'm afraid I don't see actual airtime vending machines listed in the results, but hopefully this generator suggestion is helpful for your needs.
