Based on your question asking about a Cool energy battery 1kw, I don't see any results specifically for that product. As an experimental shopping assistant, I don't have access to all listings. However, some options that could work for you are the RCT Megapower 1KVA 1000W Inverter Trolley With 1 X 100AH Lead Acid Battery for R6,649 or the Xiaomi Mi 20000MAH Redmi 18W Fast Charge Power Bank Black for R664. Both of these products provide portable battery power around the 1kw range, with the RCT option offering a larger lead-acid battery attached to an inverter for home/office use and the Xiaomi one being a compact portable power bank great for on-the-go charging. Let me know if you need any other details on alternatives!
