When a non-PPS device is connected, the power bank will simply default to its standard USB PD or other supported charging modes, delivering power at a fixed voltage and current.
In such cases, the charging speed will be similar to what you would expect from a high-quality, non-PPS power bank of equivalent wattage. The advanced dynamic adjustments of PPS will not be utilized, but the charging process will still be safe and efficient within the capabilities of both the power bank and the connected device. This means your investment in a PPS power bank will still provide excellent charging for all your USB-powered gadgets, even those that haven’t yet adopted the PPS technology.
What is the difference between PPS and regular USB PD charging?
The fundamental difference between PPS and regular USB Power Delivery (USB PD) lies in the level of control over voltage and current during the charging process. Regular USB PD utilizes a set of predefined voltage and current “triggers” or profiles. For example, it might have profiles for 5V/3A, 9V/2A, 12V/1.5A, etc. The power bank and the device negotiate to select the best available fixed profile. While effective, this can lead to inefficiencies as the power might not be perfectly matched to the device’s immediate needs, potentially causing unnecessary heat.
PPS, as part of the USB PD 3.0 specification, introduces a far more granular and dynamic approach. It allows for step-less adjustments within a defined range of voltage and current. Instead of fixed profiles, PPS enables real-time communication where the power bank can adjust its output voltage in increments as small as 20mV and current in increments as small as 50mA. This precise control allows the charging source to precisely match the device’s constantly changing power requirements, leading to higher efficiency, reduced heat generation, and optimized charging speeds, ultimately benefiting battery longevity.
How do I know if my device supports PPS charging?
Determining if your device supports PPS charging typically involves checking its specifications or the manufacturer’s documentation. Most modern smartphones, particularly flagship models released in the last few years, explicitly state support for USB PD 3.0 with PPS in their technical specifications. You can usually find this information on the manufacturer’s website, in the device’s user manual, or on reputable tech review sites. Look for mentions of “PPS,” “Programmable Power Supply,” or specific voltage/current ranges within the USB PD standard that indicate PPS capabilities (e.g., 3.3V-11V at up to 3A or 3.3V-21V at up to 5A).
Another indicator is if your device comes with a charger that advertises PPS charging, often labeled with higher wattage capabilities (e.g., 25W or 45W chargers often include PPS). If your device charges noticeably faster with such a charger compared to older, standard USB PD chargers, it’s a strong indication of PPS support. Some devices may also display “Super Fast Charging” or similar proprietary branding when connected to a PPS-compatible charger, further confirming this capability. However, always refer to official specifications for definitive confirmation.
What are the safety features I should look for in a PPS power bank?
When selecting a PPS power bank, prioritize robust built-in safety features to protect both the power bank and your connected devices from potential hazards. Essential safety mechanisms include overcharge protection, which prevents the power bank’s battery from being damaged by exceeding its designed capacity. Over-discharge protection is equally important, safeguarding against draining the battery too deeply, which can also degrade its lifespan. Short-circuit protection is crucial to prevent damage in case of accidental short circuits on the output ports.
Furthermore, look for over-current protection, which limits the amount of current flowing through the ports to prevent damage to connected devices. Over-voltage protection ensures that the output voltage does not exceed safe levels. Temperature control or thermal shutdown is another vital feature that automatically turns off the power bank if it overheats, preventing potential fire hazards. Reputable manufacturers will clearly list these safety features and often back them with certifications like CE, FCC, and RoHS, which indicate adherence to safety and environmental standards.
