Frequently Asked Questions
Can battery or solar packs run a fog machine safely?
It depends on the fog machine’s power draw. Small consumer foggers may run from a high-capacity battery if their average wattage is within the pack’s DC/USB output or if you use an inverter sized for the machine’s surge. Always check the fogger’s rated wattage and choose a power source with sufficient continuous output and surge capability; for heavy-duty fog machines, a generator or mains power is usually required.
How do I estimate how long a power bank will run my Halloween lights?
Add up the wattage of your lights, then divide the battery pack’s watt-hour capacity by that wattage. As a quick rule, a 50000–70000mAh pack (roughly 185–259Wh) can run a 20W string of lights for many hours. Factor in efficiency losses (10–20% for DC conversion, more if using an inverter) and remember that higher volume on speakers reduces runtime significantly.
Are these outdoor batteries safe in rain and cold weather?
Choose units with outdoor ratings (waterproofing or rugged ABS/resin housings) and follow manufacturer guidance. IPX7 or weatherproof cases protect against rain, but avoid submerging unless explicitly rated. Cold temperatures reduce battery capacity temporarily — store and charge packs in a warmer location when possible and bring spares if you expect prolonged cold use.
