Energy Resource for Various Operating Scenarios
The 2E-PB4002-BLACK is a portable power source capable of keeping smartphones, laptops, routers, and network equipment running on the road, in the office, or during power outages. The 40,000 mAh (148 Wh, 3.7 V) lithium-ion battery provides a significant energy reserve, and Power Delivery support up to 65 W allows you to charge even power-hungry devices without compromising charging speed.
65W Power & Compatibility with Modern Devices
The maximum output power of up to 65 W via USB-C allows you to fully power laptops and other PD-enabled devices. Support for Power Delivery, Quick Charge 3.0, and SCP protocols ensures proper interaction with modern electronics. Additionally, a flexible power distribution system is provided when connecting multiple devices simultaneously:
- Type-C1 + Type-C2 – 33 W + 32 W (up to 65 W in total);
- Type-C + USB-A – up to 33 W + 18 W;
- USB-A1 + USB-A2 – 18 W + 18 W;
- all connectors simultaneously – up to 30 W (5 V × 6 A).
When using the DC output, the Type-C2 and USB-A2 interfaces are automatically disabled to ensure stable operation and correct load distribution.
Advanced Connectivity
The model features two USB Type-C connectors, two USB-A connectors, and a separate 5.5 × 2.1 mm DC interface. USB-C supports modes from 5 to 20 V with a current of up to 3.25 A, allowing you to use the full potential of fast charging. The USB-A ports support up to 22.5 W (SCP) or up to 18 W (QC 3.0).
A DC output with a choice of 9, 12, 15, or 20 V expands the range of applications. This format is perfect for powering routers, network equipment, fans, or specialized heating and cooling clothing. USB-C and DC inputs are provided for charging the battery itself; it is recommended to use an adapter with constant power.
Smart Management & Parameter Control
The informative display shows the charge level, voltage, and current, allowing you to accurately assess the current operating mode. The K1 button is responsible for activating the device and the screen; pressing it twice turns off all outputs, and pressing and holding it switches the system to DC voltage selection mode. The default setting is 9 V, but the user can change the setting to 12, 15, or 20 V by pressing K1 (the parameter will be shown on the display). The K2 button controls the built-in LED flashlight, which is useful in the dark or during a power outage.
Temperature Protection and Operational Stability
The protection system takes into account the operating conditions and regulates the operation according to the ambient temperature.
Charging:
- 0…45 °C – standard mode;
- 45…50 °C – current reduction;
- above 50 °C or below 0 °C – the process is stopped.
Discharging:
- 0…48 °C – standard mode;
- -10…0 °C and 48…55 °C – power limitation to 45 W (PD);
- above 55 °C or below -10 °C – discharging stops.
This algorithm reduces the risk of overheating, stabilizes the load, and prolongs the battery life.
Format and Mobility
The dimensions (178.8 × 74.2 × 85 mm) and weight (960 g) indicate a significant energy reserve and wider application possibilities. The handle simplifies transportation, and the form factor is geared towards use both within urban infrastructure and in field conditions or while traveling.
