WattageViewer has received a major update!
In addition to charger details, it can now display power consumption and battery power.
Plugged in, but still losing battery?
Getting different results when you switch cables?
WattageViewer puts your Mac’s power information in the menu bar, so you can check the readings you need while you work.
This major update goes beyond adapter information. You can now see actual input power, estimated Mac consumption, and battery charging or discharging. A new window shows how power flows through your Mac, with more ways to customize your menu bar.
SEE WHAT MATTERS
Show just your input power, or add battery charging and discharging. Choose the readings you want and arrange them in one, two, or three lines.
CHECK YOUR CHARGER AND CABLE
Try different charger and cable combinations and compare the power reaching your Mac. Spot situations where incoming power cannot cover consumption and the battery supplies the difference—even while plugged in.
FOLLOW THE POWER FLOW
Open the detailed window to see incoming power, Mac consumption, and battery charging or discharging in one diagram. View the power available through the adapter connection separately from the power actually entering your Mac.
MAKE IT YOUR OWN
Choose separate icons for plugged-in and battery operation. Customize text labels, units, and the number of rows. Select English or Japanese for the app, with a separate language setting for menu bar labels.
Available readings depend on your Mac model and macOS version. Some readings may be unavailable. Mac consumption is an estimate based on available power information. Readings may take a few minutes to stabilize after connecting or disconnecting power. WattageViewer displays power information; it does not change charging speed.

Its handy when you plug-in a charger that not sure

Wattage is about Time & Energe.This app has clear purpose in mind. To read I/O feed in decimal then transfer it to eye-friendly.With Help of this app. I can have more options when comes to charging my gears.When it comes power hungry applications. I will had use 140watts to get job done. Otherwise a 86w will be friendly to Li-battery, to catch a breath.One thing tho. Electronics are somehow behaves like to our body. It had has up & down. All this are activities depended. In other words energe are not staticly balanced out, But In constantly changing floating stats.To point out that this app has some greatly potential in this category.In 2023. We getting more ports in laptops. Opened up abilities to hook up more accessories. It's sounds combersome when you dont know how long exact it gonna take to charge you gear up. If this app when well and can tell which port draw details in output. It could save lots times in research and testing.

This one allows the user to customize what shows up as far as charging wise on the menu bar
Does the job

It is a very simple toolbar utility that does the job. Results seem to be accurate. I am using it to validate different DC Car Chargers on my 2019 Macbook Pro 16in.
Do not waste your money

All it shows is your charger’s maximum charging current. Doesn’t actually show the fluctuations in charging. For example, was charging from 85 to 100% using the apple charger. It displayed 140w constantly and never fluctuated. Tested a few different scenarios and every time it only displayed my chargers maximum charge rate. Displayed nothing that involved active charging.
Developer Response
Thank you for the detailed feedback, and you’re right. Earlier versions primarily showed the adapter’s negotiated maximum wattage, not the Mac’s live charging behavior.Version 2.0 addresses this by separating:- Adapter: available maximum power- Actual Input: power currently delivered to the Mac- Mac Consumption: estimated power used by the Mac- Battery: charging or discharging powerThis makes it possible to see when the battery is charging, paused, or still discharging despite being connected to power. Availability depends on the telemetry provided by each Mac model and macOS version; unavailable live values are shown as “—” rather than being presented as a maximum wattage.We appreciate the report—it directly informed this major update.
