New Release Over-Charging Protection - Introduce Tapo Plug "Charge Guard" Feature [Beta]
This Article Applies To
Tapo P304M (UK) 1.0
Tapo P110 (US) 1.0
Tapo P115 (US) 1.6
Introduction
Charge Guard [BETA] stops the power output of the Tapo smart plug once the connected device is estimated to be fully charged. This helps reduce battery aging and prolong battery life of the electronic device.
Setup Charge Guard
1. Go to smart plug's Device Settings > Charge Guard, enable Charge Guard.
2. Custom Power & Custom Time: Set the power threshold and duration. The plug will automatically turn off when the charging power remains below xx W for xx min.
Typically, the charging rate of electronic devices slows down over time. Therefore, in order to avoid early shutdown before the device is fully charged, or early suspension of charging before the desired battery capacity is reached, it is necessary to observe the power changes and duration of the device while charging. Take an iPhone 15 for instance, when the battery is charged to 90%, the power drops to around 7W. After 20 minutes, power drops to 2W. Then in another 10 minutes, reaching full charge.
Recommend Settings*
- For mobile phones/tablets: 2W - 30min
- For laptops: 2W - 60min
- For smart watches/headphones: 1W - 50min
*The data is sourced from our laboratory tests, and actual results may vary between different types and models of devices.
Important Notes
1. Charge Guard is less suitable for low-power devices like toothbrushes, which have minimal charging power and no marked decrease in power during charging. This feature might prevent these devices from achieving a full charge.
2. Many factors can affect charging speed, including ambient temperature, charger quality, cable condition, and whether the device is in use. The recommended settings are for reference only.
3. This feature cannot precisely limit the battery level. If you want to limit the charging capacity to further extend battery life, you can enable the "Optimized BatteryCharging" feature available on your mobile phone (the name and functionality may vary by brand).
4. Even when the device's Ul interface shows the battery fully charged, the battery may still be in a low-power charging state to optimize battery saturation. This state usually lasts for about half an hour.

I use the p115 for charging my ebikes. At the moment i'm monitoring powerusage manually in order to stop at around the 80 percent mark.
A raise of the upper limit of 20 watts to something about 300 watts would be higly useful for me also.
Actually this is what i hoped i would get when buying the first of the p115 plugs.
Thanks for the development so far.

@Wayne-TP Do you know if the P304M is meant to show a charge guard notification when a device has been switched off like the P110M plugs do?

@wattagemon The same feature should be consistent across different models.
