## Review summary

Users broadly praise Charge Meter for testing chargers and cables, showing wattage, and providing real-time battery discharge data. It's perceived as reliable and easy to use across devices, with many reviews noting it helps compare chargers and monitor battery health. The main drawbacks are intrusive, sometimes locking ads that hamper usage, and accuracy issues on some devices (notably two-cell battery phones) that can misreport current or require a toggle option to fix. Overall, strong value for charger testing and monitoring, but ad experience and device compatibility are recurring concerns.

### Pros

- Helps identify fastest chargers and cables using wattage readings.
- Real-time battery discharge rate helps spot apps draining power.
- Generally reliable and well-liked across multiple devices.
- Simple, easy-to-use interface for tracking charging status.

### Cons

- Intrusive ads that disrupt usage, including pop-ups and locking the app/phone.
- Inaccurate amperage/wattage readings on certain devices (e.g., phones with two-cell batteries) and no toggle to fix.
- Long-duration ads that slow down or interrupt the app experience.
