Functions

▶ Can be charged by solar energy, vehicles and municipal electricity, fastest full charged time is 4h

▶ Covers 99% USB charging device (mobile phone, ipad, camera)

▶ Providing USB QC3.0 port which supports QC fast charge protocol (mobile fast charge)

▶ Providing TYPE-C, 45W, PD protocol, directly adapts to PD protocol laptop power supply

▶ Providing DC 12V car cigarette lighter interface, which can be supply power for car emergency start and other on-board electrical appliances

▶ Providing DC5521, 12-13V power supply for UAV, aviation models and outdoor applications

▶ AC 110V or 220V port can supply power to most small and medium-sized household appliances (TV, electric fan, indoor lighting)

▶ Built-in LED lighting, providing four modes of low brightness, high brightness, SOS, and flash

Technical Features

• All DC transformations use synchronous rectification technology, including charging, USB, QC, TYPE-C (PD), DC12V with high efficiency (93% to 98%), low heating and indirectly increasing battery capacity by 5%-10%.
• Adopting EV grade A lithium ion cell, whose life time is 2-3 times longer than ordinary cell.
• AC uses pure sinusoidal wave and non-corrected wave to provide better power quality for AC power equipment and radiator enclosure design (no fan, mute version).
• The car does not need to open the hood, the car starts directly inside, the operation is easier. Flexible start-up, no impact current, reverse connection and other risks, battery more safe and durable.
• Real MPPT photovoltaic charging, non-ordinary solar charger, 10% higher utilization rate than an ordinary solar charger.
• Adaptive charging, voltage 17-24v, power 60-120w, and the optimal charging current is automatically adjusted according to the adapter. Protect the adapter while the fastest charging.
• BMS has dual high and low pressure, high and low temperature, overcurrent protection, software balance, SOC measurement, and other functions, which can guarantee the stable and reliable operation of battery.
• The whole system is shut down in a completely power-down mode. The power consumption of the whole system is less than 100ua, and only 1/3 to 1/2 of the same kind of products are available. Provide the best solution for long time storage.
• The design of uniform internal resistance, such as the convergent use of battery module, ensures the uniform use of electric cell, prevents uneven attenuation, and extends the service life of battery module by more than 10%.
• Aluminum alloy shell anodized, panel using PC hardened material, anti-ordinary scratch, remain newly after years of using.
