Product Description
The ES-400 backup power supply is one of the outdoor portable power supply products of our company. Using aluminum alloy shell material. light and portable. the appearance is fashionable and generous. the core uses power type 21700 lithium battery. using dual-phase inverter fast charging technology. without external adapter. Provide two different voltage modes: AC output and DC output to meet the power demand of users. This product can be used as UPS power and as outdoor emergency backup power.
This product has built-in large capacity lithium battery. total capacity 399.6WH. 108000mAh. Providing a steady stream of power for the load. It is also widely used as a backup emergency power supply for indoors and outdoors.
Dual-phase inverter AC charging. 220V (110V) AC output. two 12V DC outputs, two USB3.0 outputs. with LED lighting lights. with electric quantity display. Suitable for a variety of different equipment. such as drones. portable ventilators. medical devices. mobile phones. tablets. laptops. desktop computers. small printers. various lamps. small fish tanks. photographic equipment. electric scooters. etc. Great convenience for users to travel at home, outdoor work. camping picnics. mountaineering expeditions. etc.
Dual-phase inverter technology, using the output power tracking technology. independently calculate the output power. can bring the perceptual and capacitive load exceeding the rated power. without causing output interruption.

When using energy storage products, you should understand what is and what is WH . and the difference between them, so as to safely buy the products that meet your needs. The analysis is as follows.
1. W represents watts in the energy storage power supply. that is, the size of the output power. For example. the output power of 500W means that it can drive devices of less than 500W. and the output power of 1000W means that it can drive devices of less than 1000W.
2. Before using the equipment. we must know the power (W) of the equipment before using it. otherwise it may cause energy storage power protection and cannot be used. At this time. after the equipment is disconnected. the energy storage power supply can be used. If it cannot be started, it can be restored after charging.
3. WH represents watt-hour in the energy storage power supply. that is. the capacity size of storage. For example. for energy storage products with a capacity of 600 WH. the equipment you use is 50W which can use time is about 12 hrs(600 WH / 50 W =12 hrs). For example, for energy storage products with a capacity of 1200 WH. your equipment is 1000W which can use time is about 1.2hrs (1200WH/1000W=1.2hrs). That is to say, the power of the equipment is low the discharge time is relatively long. On the contrary. the discharge time is relatively short when the equipment power is large.

PCBA function declaration
UPS function description
The product we refer to has the UPS function. which is characterized by when the electric supply input. the inverter also has the output. at this time we connect the load such as computer. when the electric supply suddenly power off. to ensure that most products will not be caused by the load shutdown phenomenon after the power failure. this function is the UPS function. The UPS function with switching time is also considered by users as EPS function. that is. backup. The outdoor portable power supply with this function can not only be used outdoors, but also can be connected to computers. TVS. routers and other devices used at home. It will not cause the situation that the equipment cannot be used after the mains power failure.

Domestic many factories are no design capability. they sell back after the PCBA from the outside. return to the factory and then to assemble. after complete test, shipment.
Our factory all PCBA is designed by myself. battery protection board in the making. we design inverter we have our own plan. charging circuit part has its own patent technology. from the design of the PCB to the completion of PCBA. and assembled finished products. with the aging process of three times.
From another factory owners to sell PCBA. from hezekiah sell BMS. and so on. all of the materials are purchased. not design capability. so the price is high. Our actual product shipment price is the cost of their factory. We can earn money is just a PCBA.
We are design company. the original factory. can be customized with different specifications. different requirements of products. custom speed. high success rate.
