I. Core parameters and performance

(I) Power supply capacity

·Capacity and power: Equipped with 12V 50AH lead-acid battery, providing stable power reserve; 500W pure sine wave inverter output, adapted to 220V/110V ±10% voltage, to meet the power needs of multiple devices such as mobile phones, computers, small appliances, such as charging laptops outdoors and making coffee in the camp, stable and interference-free.

·Rich output interface: 4 USB 5V interfaces, 6 DC 12V interfaces, 2 AC output ports, multiple devices can be charged at the same time, mobile phones, tablets, and Bluetooth speakers can be charged together at parties without delay.

(II) Charging method

·Flexible energy replenishment: supports 220V/110V mains power and 15V-40V solar panels (maximum 250W) charging. If there is no mains electricity outdoors, you can recharge by basking in the sun; you can plug in at home at any time to quickly restore power and be at ease in case of sudden power outages.

2. Practical design and advantages

(I) Portability and durability

· Lightweight and easy to carry: 18kg weight, with a handle, easy to carry for outdoor camping and construction site operations; 286206255mm size, does not take up space, can be placed in the trunk or corner.

· Reliable protection: metal shell, anti-fall and wear-resistant; -10 - 40℃ wide temperature operation, -20 - 70℃ storage (no condensation), severe cold and heat, outdoor bumps, stable power supply without "dropping".

(II) Intelligence and safety

· Real-time monitoring: The LED screen clearly displays the power, voltage, and power, the power usage status is clear at a glance, and the remaining power is known to avoid the embarrassment of equipment running out of power.

· Comprehensive protection: pure sine wave inverter to reduce electrical damage; overcharge, over-discharge, overload, short circuit protection, equipment and battery are safe, use with confidence.

(III) Uninterruptible and expansion features

· Uninterruptible power supply (UPS) function: When the city power is suddenly interrupted, B-500 can switch to its own battery power supply in milliseconds to ensure that computers, routers and other equipment continue to operate, data is not lost, and the network is continuously connected. It is very practical for home office and small computer room emergency.

· External battery expansion: Support external lead-acid batteries of the same specification to easily expand capacity. For long-term outdoor operations and large-scale camping activities, after connecting to an external battery, the power life is doubled, and there is no need for frequent charging, and the power consumption is more relaxed.

III. Wide range of applicable scenarios

· Outdoor scenarios: Power lighting and audio when camping to create a warm atmosphere; RV travel, supplement the power consumption in the car, and make tea and watch TV without worrying about electricity.

·Emergency scenario: When the power is off at home, temporarily power the refrigerator and lighting to maintain basic life; when working at construction sites or outdoors, power the tools and equipment to ensure that work continues.

·Office scenario: As a UPS backup power supply for office computers and servers, it can seamlessly connect when the mains power is abnormal, avoiding data loss and business interruption, and protecting office stability.

B-500 portable power station, with flexible power supply, reliable performance and comprehensive protection, becomes your "power guarantee officer" for outdoor travel and emergency power backup, and can provide a bottom line for various power needs at any time!
