Power that comes with you. The Kapa Energy Q300 is built around a simple idea: power should be portable. The unit packs a 313Wh lithium battery and a 300W pure sine wave inverter into a 4kg case roughly the size of a small briefcase, with a carry handle and an LCD screen on the front. Pick it up, take it wherever you're going, plug things in. The output side has every port a modern user actually needs a standard AC outlet, three USB-A ports, a USB-C port with Power Delivery for fast laptop and tablet charging, and a regulated 12V DC output for camping accessories and dashcams. Pure sine wave output matters here: it's the clean, mains-quality waveform that laptops, TVs, CPAP machines, audio gear and other sensitive electronics expect without the buzzing, heat, or shortened device lifespan that modified-sine inverters can cause. Add the integrated LED light (with SOS function) and the LCD display showing real-time battery state and output draw, and you've got a self-contained power solution that works in a tent, in a car, on a stoep during load shedding, or on a mobile job site. What 300Wh actually runs: Smartphone (~10Wh per charge): around 2530 full charges Tablet (~30Wh): around 89 charges Laptop (~50Wh per charge): around 45 full charges Wi-Fi router (~10W draw): around 2225 hours LED lights (~5W): roughly 50+ hours Small desk fan (~20W): around 1214 hours 32" LED TV (~50W): around 45 hours CPAP machine (~35W): around 78 hours (verify with your specific unit) These figures assume reasonable inverter efficiency (~8590%) and vary with actual load, temperature, and battery condition.
