• Smartphone (10–15W): multiple full charges
• Laptop (30–60W): several hours depending on model
• CPAP or small medical devices: compatible for temporary use—check your device wattage
• Small appliances (under 300W): brief operation, watch peak limits

What ports and outputs does the unit include for powering devices?

The MARBERO M823 provides a wide array of outputs so you can run AC or DC devices and charge USB gadgets simultaneously. It uses a pure sine wave inverter for stable AC power and includes fast-charging USB ports for quicker device top-ups.
