Charge Your PC Faster Up to 65W at USB Power Delivery 3.0 Speeds with the Portable Dell 65W PD Power Bank

Dell has gone very aggressively on power bank design with the release of the Dell 65W PD Power Bank as the first 65W USB Power Delivery 3.0 capable power bank in the market. While many ac adapters can provide such high level power charging, power banks mostly support much lower output such as 30W USB Type-C charging by the Tronsmart Brio USB C Power Bank 20100mAh PD Portable Charger. With 65 watts, the Dell 65W PD Power Bank should sufficiently charge most USB Type-C notebook PC's, tablets, and phones rapidly using USB Power Delivery 3.0 technology.

Unlike power banks which use a single Type-C port for sourcing/sinking power, the Dell 65W PD Power Bank has a USB Type-C cable plug for sourcing power and and a USB Type-C receptacle for sinking power. For Power Delivery charging out, the Dell 65W PD Power Bank supports 5 volts @ 3 amps (15 watts), 9 volts @ 3 amps (27 watts), 15 volts @ 3 amps (45 watts) and 20 volts @ 3.25 amps (65 watts) power profiles over the USB Type-C cable plug that is fitted to the power bank. See how it charged the Dell XPS 15 9575 (2-in-1) PC in this review where the power bank was also seen to advertise variable power up to 68.25 watts (21 volts @ 3.25 amps). However this Augmented Power Data Object (APDO) with Programmable Power Supply (PPS) is not listed on the power bank's box and the power bank also seems to reject PPS requests from the sink. Dell has also claimed that when connected to a 90W based external ac power adapter, the power bank can use up to 4.5 amps current at 20 volts to enable 90 watts charging although we only saw the power bank drawing much lower power when being charged by the Dell 130W USB Type-C AC Adapter in this review. The power bank allows charging in up to 20 volts when attached to a compatible USB Power Delivery based ac adapter.

The Dell 65W PD Power Bank also includes a standard 10 watts based USB Type-A port to connect to USB peripherals as well as a power button with battery charging indicator.    

Using the USB Power Delivery Compliance C2 Tester from Granite River Labs to run just a subset of the full USB Power Delivery compliance test suite, we can confirm that the Dell 65W PD Power Bank supports these fixed PDO's: 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), 45 watts (15 volts @ 3 amps) and 65 watts (20 volts @ 3.25 amps) for charging. We can also see that this power bank supports USB PD 3.0 based Programmable Power Supply (PPS) and has a Augmented Power Delivery Object (APDO) with 3-21V voltage range even though this is not shown on the box itself. Note compliance failures were also observed.
