KLEIN TOOLS Voltage Testers Editorial Review
The Klein Tools USB Power Meter (ET900) has garnered a positive reception from users who appreciate its straightforward functionality and robust design. This compact digital meter enables users to effectively monitor the output values—voltage, current, capacity, energy, and resistance—of USB-A and USB-C ports, making it a practical tool for troubleshooting various charging devices, such as wall sockets, chargers, and power banks. Users commend the ET900 for its clear and legible display, despite some notes on the screen's size. The build quality is widely praised, with many acknowledging its durable Construction. However, some wished for slightly larger dimensions for enhanced usability. The attached cables, while somewhat stiff, do not detract significantly from the overall experience, especially since these contribute to the unit’s durability. One notable drawback is the unit's limitation when it comes to cable compatibility: USB-A inputs must connect with USB-A outputs, and storing values when input charges fail due to low power is impossible. This could pose challenges for users who experience frequent drops in input power or those unfamiliar with the product's written guidance on USB-C connections. Overall, users express satisfaction with their purchase of the Klein Tools USB Power Meter, often recommending it as an essential debugging tool for charging issues. The feedback highlights that while there are certain restrictions and room for improvement, the device effectively serves its purpose in monitoring USB power output. **
