POWERTECH MB3776 Portable 500Wh Power Station

INTRODUCTION

The MB3774 portable power stations are the result of years of power supply manufacturing experience combined with extensive user feedback. With its compact design, huge capacity, light weight, high power, and ease of portability, the new design uses an effective lithium battery as the main body of energy storage.

It offers you an easy mobile power solution and is widely used in outdoor settings, medical and fire rescue operations, outdoor recreation, emergency conditions, environmental monitoring, and other applications.

FEATURES

• Intelligent automatic dynamic charge and discharge management platform
• The colour LCD display would show the battery capacity, voltage, output power, and remaining time for charging and discharging.
• Lightweight and compact design
• Pure sine wave, high precision, low ripple, and SPWM (pulse width modulation) voltage output
• Isolated pure sine wave AC 240V output
• Built-in rechargeable power with high capacity, long life, and efficiency lithium-ion battery
• QC3.0, 5V/2A, wireless charging and Type-C output, can be used for charging digital products such as mobile phones;
• AC (AC240V) and DC (DC12V/10A, USB5V/2A, Type-C, can supply power at the same time
• Safety design seven protections: short-circuit protection, over-load protection, over-temperature protection, over-charge protection, over discharge.

USAGE INSTRUCTIONS

Procedure

1. Ensure that the load power is within the rated power of this power station. If not, please choose a higher power station.
2. To begin, press the power button and then the switch. When the indicator is on, the output is turned on, and the device can be charged.
3. After use, please turn off the power button and charge the power station inti me.
4. Charging method: Insert the charger into the DC audio input port, the AC output and DC 12V output will be automatically turned off, but USB charging can be used. After charging to 100%, please continue charging. The charging function will automatically stop when charging is complete.

Note: Overload, overheating, or low batteries will automatically activate the protection function and shut down the power station.

Operation Precautions

When using the power station, please strictly follow the operation steps:

1. Place in a cool, dry location away from liquids, gases, and oils, with at least 5 cm of space around it to dissipate heat.
2. Equipped with a fully automatic charger, AC output and DC 12V output will be automatically turned off during charging, only the LED lights, USB and wireless charging functions can be used. After charging for 6 to 8 hours,, please unplug the charger before use. If it is not in use, please turn it off to save power and recharged it every three months.
3. When no function is used, it will automatically shut down after two minutes. You need to press the power button again to reactivate it.
4. When using USB charging, if the power exceeds 5 watts, the cooling fan will work every 6 minutes; When USB charging current is less than 2 watts and AC power is less than 10 watts, the LCD display will not display the output power.
5. When the temperature inside the power station exceeds 50 degrees Celsius and the load power exceeds 20% of the rated power, the cooling fan kicks in.
6. In general, an AC load device with less than its rated power can be used normally, but the startup power of some devices often exceeds its rated power. For example, the startup power of an inductive load device is generally 6-8 times its rated power, and the startup power of LED lamps is about dozens of times its rated power. If the startup power exceeds the peak power of the power station, over-load protection will be triggered, and the power station will automatically shut down.

APPLICATION SCENARIOS

Portable power stations are widely used in medical rescue, emergency communication,
environmental monitoring, fire rescue, military camping training, outdoor offices, power outages, no electricity areas, telecom network installation, military information construction, geographic working, oil exploration by miners, architectural design surveys, water conservation and water affairs testing, outdoor photography, field research, etc.

TROUBLESHOOTING

while, then restart the USB output
AC no power output| The internal battery is overheating and becoming overloaded.| Restart the AC output at the ideal operating temperature
Charge failure| The internal battery is overheating, and the charging startup power is excessive.| Try unplugging and plugging in the charger several times
Power failure| The internal battery is overheating, the battery is low.| Restart after the temperature has cooled, or plug in the charger to activate charging.
