Hi @s1tantn,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand looking for a new charger for your HP Envy M7, it's important to consider several factors to ensure compatibility and performance. Here are the key aspects you should look into:
 

Voltage and Ampere: The output voltage and current (ampere) of the charger should match the specifications of your original charger. If you've found a charger with the same voltage and higher or equal amperage (in this case, 100-240V~1.7A compared to your original 100-240V~1.6A), it should be fine. A slightly higher amp rating is usually acceptable as it indicates that the charger can supply the necessary current. However, the voltage must match exactly.

Plug Size and Polarity: Ensure that the charger has the correct plug size and polarity (the position of the positive and negative contacts) for your device. This ensures a proper connection and functionality.

Brand and Compatibility: It's recommended to use a genuine HP charger or a charger certified to work with HP devices. This ensures quality and reduces the risk of damage to your laptop.

Input Specifications: The input specifications (100-240V~50-60Hz) you mentioned are generally universal and should work as long as they match the power supply capabilities of your location.
