UpBright Micro USB 5V AC/DC Adapter Compatible with PEAKME CK-W355

In this review the reviewer tested the UpBright Micro USB 5V AC/DC Adapter as a direct replacement power supply for the PEAKME CK-W355 wrist blood pressure monitor. The bottom line: this adapter is for anyone who needs a simple, tested replacement that delivers stable 5V DC power and broad international compatibility. The reviewer found it dependable for home use, offers built-in protections against common faults, and is a practical choice when the original charger is lost or the internal rechargeable pack needs a reliable external supply.

Key Features

• Worldwide input: The adapter accepts 100-240VAC at 50/60Hz so it can be used internationally without a voltage converter.
• Micro USB 5V output: Supplies a steady 5V DC output via Micro USB which matches the power requirement of the PEAKME CK-W355 monitor.
• Protection circuitry: Includes OVP, OCP and SCP protections to reduce the risk of damage from over voltage, over current, or short circuits.
• Tested units: Each unit is reported as tested and in great working condition, reducing the chance of receiving a defective charger.
• Compact switching PSU: The small wall power supply is easy to store and carry for home or travel use.

Who It's For

The adapter is ideal for owners of the PEAKME CK-W355 wrist blood pressure monitor who need a reliable replacement for a lost or worn charger, or who prefer using an AC supply instead of internal batteries. It also suits users who travel, since the 100-240VAC input covers most mains standards worldwide.

It is not for users who require a proprietary connector or a different voltage than 5V, and those seeking an integrated long cable or specialty medical-grade certified PSU beyond the listed CE/CCC/ROHS markings should check equipment-specific guidance or the device manufacturer.
