battery power pack 300W

Nowadays, more and more people will drive to camp outdoors during the holidays, which is not only a realization of parenthood but also a relaxation. At this point, they needed a device to support their home’s travel power, and that device was portable energy storage.

Recently, QH outdoor multi-functional portable energy storage power supply market, built-in 307.84Wh large capacity battery pack, 110V (300W) pure string AC output, integrated USB and wireless charging and other functions, as well as a digital display screen, fully functional. The following charging head network will be dismantled in detail, let’s take a look at the design and process of the energy storage power supply.

QH Multi-functional portable energy storage power supply is an orange and black body, the body corners are rounded, and the surface is frosted. The front has five output ports and supports AC/USB/Type-C/ vehicle charging/wireless charging output, as well as lights, features are rich.

Portable Power Station Techniques

We are Specialized in technlogy development of subpackage, BMS and controls of lithium battery, power frequency conversion for discharging, and solar charging.


1. Charging disconnected when the overall voltage reaches the preset value.

2. BMS single cell charging for dual protection, and a 2nd layer protection is activated if the 1st simulated charging fails. The BMS is certified for UL2054.

3. Over temperature protection, the charging is disconnected when the battery cell is out of the 50+/-5℃ range or below 0℃.

4. PTC protection, disconnected automatically when charging current is abnormal.

5. Over-discharge protection

6. Overcurrent protection

7. Short circuit protection


Bidirectional PCS for Quick charging

1-2 hours for a full quick charging with this technology


MPPT solar charging

Self-developed software algorithm,enhanced charging performance
