Unboxing and Features
The Newsmy portable power station arrived with all the necessary accessories: a fast PD charger with a USB-C to USB-C cable, a car adapter for charging via the cigarette lighter, and an MC4 to barrel connector for solar panel integration.
The unit boasts a 270Wh (24Ah) Lithium-Magnesium-Iron-P4 battery, promising over 2500 charge cycles. Safety features include overload, short circuit, over-voltage, low-voltage, over-current, over-temperature, low-temperature, and reverse polarity protection.
A built-in 6W LED light offers four modes: high brightness, soft light, flash, and SOS. The compact design features a carrying handle and weighs just over 5 lbs.
Capacity Test and Output Ports
A full charge takes around 5 hours at 65W using the included AC adapter. I tested the battery capacity using a discharge tester, confirming its 24.2Ah capacity (approximately 91% of the advertised 270Wh).
The power station offers a variety of output ports: two USB-A ports (output only), and two USB-C ports supporting both input and output up to 100W each. A DC output with a barrel connector is also available for various accessories.
The manufacturer claims it can charge a laptop 4-5 times, a tablet 6-7 times, and cell phones over 20 times. It even claims to run a CPAP machine, though I didn’t test that.
Real-World Usage and Charging Devices
I tested the power station by charging various devices simultaneously: a GoPro camera, a small photography light, and a wireless microphone. The unit handled the load smoothly, drawing around 14W.
I also added a small fan powered by the DC adapter, pushing the power draw to 16W. The power station demonstrated its ability to run multiple devices simultaneously for extended periods.
This versatility makes it ideal for camping, outdoor photography, or any situation requiring portable power for multiple devices.
Car Charging and Solar Panel Integration
The car adapter initially displayed an error code (Error 10: DC charge low voltage). This was resolved by running the car's engine, providing sufficient voltage for charging.
The included 100W solar panel features foldable legs and magnets for easy setup. It uses MC4 connectors and includes extension cables for flexible placement.
In my test, the solar panel delivered 78-89W under partially shaded conditions, highlighting its efficiency and ease of use.
Conclusion
The Newsmy 270Wh portable power station exceeded expectations in my tests. It delivers reliable power and numerous charging options, making it a versatile solution for various needs.
The inclusion of a 100W solar panel further enhances its practicality, providing a sustainable charging solution for off-grid situations.
Overall, this power station is highly recommended for anyone seeking a portable and efficient power source for their electronic devices, whether camping, travelling, or for use in a workshop.
