7. 220V AC output for the more use of household appliances

▲ The USB outputs are very suitable for charging electronic devices, but it is impossible to start with some devices that only support AC charging. Yoobao EN300WLPD outdoor power supply is equipped with an AC outlet, delivering a 220V pure sine wave with an output power of 300W right for those AC-powered equipment.

▲ The rich outputs can charge multiple devices at the same time, ranging from mobile phones to small household appliances.

▲ Although it is called an outdoor power station, it has never been confined to outdoor scenarios, it is also a good choice for power storage at home. Compared with generators, Yoobao EN300WLPD power station has many advantages, such as quietness, no chemical pollution and noise pollution, easy storage, convenient charging and so on.

▲ If there is a sudden power outage at home, you can use this power station as a backup to keep your home devices powered on. Especially when you are at home at night, it is inconvenient to do anything when the power is suddenly cut off, and you will be at a loss what to do. But if you have Yoobao EN300WLPD, you don’t have to worry about it. It can seamlessly power devices such as electric lights or internet modems, so that the home can be powered and connected to the Internet.

8. Efficiency Test


▲ Since Yoobao EN300WLPD outdoor power station supports USB-C two-way high-power fast charging, we also collected its output efficiency through USB-C. First, we tested the output efficiency of the power station at the 9V2A gear to test the full voltage. Both the current and power platforms maintained a stable output state, and the whole process took about 15 hours and 28 minutes. The released energy is about 281.3097Wh, so the efficiency of the power supply is about 281.3097/256=109.88% when outputting at 9V2A gear.

▲ Finally, the output efficiency of the power supply was tested at the gear of 20V3.25A. It was the same as 9V2A. The entire output in the test was very stable without any fluctuations. The whole process took about 4 hours and 18 minutes. The released energy is about 277.8594Wh, so the efficiency of the power supply is about 277.8594/256=108.53% when outputting at 20V3.25A.

Here the output efficiency of more than 100% does not mean that the batteries inside can achieve more than 100% output. It is because when calculating the efficiency, the data is based on the nominal 256Wh in the parameters. The actual battery energy in the power station is higher than the nominal 256Wh, so the result could be more than 100% in the calculation.


9. Temperature Rise Test

In addition, we also measured the temperature control performance of Yoobao EN300WLPD. The temperature was collected the after a continuous output of about 300W for half an hour. The test environment is based on an incubator at a temperature of about 25°C. 

▲ The highest body temperature collected before the test started was 29.8°C.

▲ Half an hour later, the highest temperature of the shell was measured at 42.7°C, with a temperature rise of 12.9°C.

▲ On the other side, the measured maximum temperature is 38.9°C, with a temperature rise of 9.1°C. From the thermal image, it can be seen that the internal heating area is mainly concentrated on the side of the fan, which is also considered for faster heat dissipation.


The look and feel of Yoobao EN300WLPD outdoor power station is quite satisfactory. It has a built-in 256Wh battery energy, and uses a high-density lithium iron phosphate battery pack of the same type as Tesla's cobalt-free batteries. Long life, durable, and higher safety, it can prolong the service life of the product, and it does not contain heavy metals and rare metals, which is relatively more environmentally friendly. And the weight of the power supply itself is only 3.1Kg, very light for driving and camping.

The power station itself supports AC power line input, USB-C input, which supports an input power of 65W; conventional DC input, which supports an input power of 60W. It generally takes about 6 hours and 35 minutes to self-charge through the built-in AC power cord, and about 6 hours and 50 minutes to self-charge through USB-C, and the overall difference is not big.

In terms of output, the built-in 220V AC pure sine wave output interface supports an output power of 300W, the USB-C port can supports an output power of 65W, and USB-A supports an output power of 18W. The USB interface can charge the devices ranging from mobile phones to laptops without the problem of charger occupancy. The AC output interface can charge laptop, drones, coffee machines and other equipment at the rated power below 300W. The built-in lighting is also very practical for outdoor nights.

The USB interface supports fast charging protocols such as PD, Apple2.4A, QC2.0, QC3.0, AFC, FCP, SCP and PE, with five fixed voltage gears of 5V3A, 9V3A, 12V3A, 15V3A, 20V3.25A and two sets of PPS gears of 3.3-6V 5A and 3.3-11V 3A. Not only can it directly charge most of the devices, but it is also in a fast charging mode, and it will be more convenient to charge electronic devices. Lightweight, portable, and functional, it is a good choice for outdoor camping or emergency storage at home.
