Keep your work-from-home laptop running during loadshedding with a pure sine wave UPS for the router, full laptop charge before a scheduled cut, and mobile data tethering as a backup. Most modern ultrabooks last 6-10 hours off a charge, so the network is usually the first thing to go, not the laptop.
🌐 Router is the real failure point
Your laptop has a battery. Your router does not. Plug your fibre ONT and Wi-Fi router into a small UPS sized for their combined 15-30 W draw. A 600 VA UPS runs a typical SA fibre setup for 3-5 hours, covering Stage 4 and Stage 6 blocks.
🔋 Laptop charging discipline
Charge to 80-100% before a scheduled outage. If your business laptop supports battery charge limits (Dell, HP, Lenovo ThinkPad, ASUS ExpertBook all do), set to 80% for long-term health. Only charge to 100% the night before a loadshedding day.
📱 Mobile data fallback
Tethering from your phone keeps video calls alive if your home router dies. Rain and Vodacom LTE work well in most SA cities. Create a Windows mobile hotspot profile in Settings > Network > Mobile hotspot so Teams and Zoom reconnect automatically when Wi-Fi drops. Keep a USB-C hub with Ethernet for when you are tethering to a desktop.
Close non-essential apps during loadshedding to extend battery life. Each Chrome tab uses roughly 50-100 MB of RAM plus CPU cycles. Switching to Edge in battery saver mode, closing Slack, and pausing OneDrive sync adds 30-45 minutes of runtime on most laptops.{{/TipBox}}
🖥️ Backup hardware for critical work
For regular heavy deliverables, a second power bank with 100W PD output lets you fast-charge the laptop during a short cut. Look for 20,000 mAh banks with USB-C PD, which add 1.5-2 hours of laptop runtime per full bank charge.
