65W USB Type-C PD Power Bank DIY Module – Real Power in a 20×20 mm Form Factor
Want to build a serious power bank instead of one that only handles phones? Or perhaps you need fast USB-C charging for your own custom project without relying on a commercial adapter? This module delivers just that — a genuine 65W, universal protocols, and a footprint so small it fits anywhere.
Note: The output voltage cannot exceed the input voltage. To achieve a 20V output (required for laptops), the power supply must provide a voltage higher than 20V DC.
Why choose this module? (Key benefits):
- No-compromise 65W — charges compatible USB-C PD laptops at full speed, not just phones
- Automatic voltage negotiation — 3.3V to 21V, automatically tailored to each connected device with no manual settings required
- Compatible with any modern smartphone — PD3.1 PPS, QC3.0, Huawei SCP/FCP, Samsung AFC, Apple Protocol, BC1.2 — there’s practically no phone it can’t fast charge
- 92–97% efficiency — less than 3% power loss means less heat and more runtime from the same battery
- Ultra-low standby current under 3 mA — crucial for power banks: won’t drain your battery when nothing is plugged in
- 20×20 mm footprint, 7 grams — fits easily into any 3D-printed enclosure or standard power bank case
Details and Performance
The module accepts any DC input source between 8V and 30V — Li-Ion packs, LiFePO4 batteries, or bench power supplies. At the output, the USB Type-C interface automatically negotiates voltage and current with the connected device according to PD3.1 and PPS standards, with zero user intervention. An output ripple of less than 200 mV ensures a stable power supply, eliminating spikes that could stress your device’s battery or electronics. For loads near the 65W limit, ensuring proper airflow or attaching a small heatsink is recommended for safe continuous operation.

Frequently Asked Questions
Can I use this module to charge a laptop via USB-C?
Yes, provided that your laptop supports USB-C Power Delivery charging and you supply an input voltage higher than 20V DC. The output voltage cannot exceed the input voltage — keep this in mind when choosing your power source or battery pack.
What power supply should I use?
To achieve the maximum 65W output, you need a stable DC power source between 22V and 30V, capable of delivering at least 3A. LiFePO4 or Li-Ion packs with the appropriate voltage work brilliantly for DIY power bank applications.
Does it work with phones that don’t support PD?
Yes. Compatibility with BC1.2, Apple Protocol, QC2.0/3.0, Huawei FCP/SCP, and Samsung AFC covers practically every modern smartphone. The module automatically detects the supported protocol and adjusts the charging profile accordingly.
Does it require a heatsink?
At light and medium loads, the efficiency of up to 97% keeps temperatures low without extra cooling. For continuous use near 65W, a small airflow or a compact heatsink will significantly extend the module’s lifespan.
Are the 20×20 mm dimensions small enough for a compact DIY power bank?
Yes — its 20×20 mm size and 7 g weight make it one of the most compact 65W modules available. It drops right into 3D-printed cases or standard power bank housings with no fuss.
