Sample Product
800W Portable Power Station Model P800The P800 Power Station is a powerful and reliable power source that, with its advanced design and LiFePO4 battery, meets your need for stable power in any situation. This device is the best option for offices and small businesses, essential home appliances and power outages.Key Features:•Output power: 800W - suitable for starting and charging essential devices•Battery capacity: 512Wh - reliable power supply for several hours of use•Cell type: LiFePO4 with high durability and safety•Long cycle life: more than 4000 charge and discharge times•Side flashlight (optional): can be added for $5 for use in emergency situationsWhy the P800 is a smart choice
With the P800 (800W continuous power and 512Wh capacity) we can roughly calculate how much each device will work. I assumed the AC output is used with an efficiency of about 85%; that is, the usable energy is ≈ 435Wh.
Rule of thumb: Operating hours ≈ 435 ÷ device power (watts)
Approximate times for each device (single)
•Laptop (average 60W): ≈ 7.3 hours
•Cordless phone/base (5W): ≈ 87 hours
•Phone charger (10W while charging): ≈ 43.5 hours (of course, consumption decreases after the battery is full)
•Small printer – standby mode (5W): ≈ 87 hours
•Small printer – when printing (average 200W): ≈ 2.2 hours (instantaneous consumption may reach several hundred watts, but remains below 800W)
•Desktop fan (40W): ≈ 10.9 hours
•Two 10W bulbs (total 20W): ≈ 21.8 hours
Suggested combination scenario
•Laptop (60W) + cordless phone (5W) + Phone charger (10W) + Fan (40W) + Two 10W lamps (20W) + Printer on standby (5W)
Total consumption ≈ 140W → Working time ≈ 3.1 hours
•Same combination without fan: ≈ 4.35 hours
•Same combination without laptop: ≈ 5.44 hours
Important notes
•If you use USB-DC outputs, the efficiency will be better and the times will be slightly longer.
•The actual consumption of each device (especially laptop and printer) varies; the above numbers are approximate.
•The total simultaneous power should not exceed 800W (for P800)
