Choose a single-port charger when one laptop is the entire charging job. There is no second connected device to reduce its allocation. The useful question is whether the charger offers the voltage and current your laptop accepts, with the correct plug and cable for the trip.

This research comparison covers Anker Nano II 65W A2663 and Rolling Square Supertiny 65W, US plug. We selected them for their documented 65W single-output design and published power specifications. We have not tested their sustained power, heat or fit in crowded sockets. They are not interchangeable with Anker A2667 multiport chargers or Supertiny 100W.

Compatibility before size

The A2663 manual identifies its electrical rating. Rolling Square’s specification distinguishes plug versions and gives the fixed and PPS outputs. A broad phone compatibility list is not proof of a particular fast-charging mode.

For a laptop that requests 20V at 3.25A, the published rating is relevant; it does not establish the power delivered in every workload. Check the laptop maker’s USB-C charging requirement. A model built around a larger original adapter may charge more slowly or lose battery charge during demanding work. A proprietary charging socket does not become USB-C compatible because this charger has enough watts.

The cable is part of the purchase

Both products’ 65W maximum exceeds 60W. Check the cable’s supported current and power rating rather than treating any USB-C cable as equivalent. A cable limited to 3A cannot carry the 3.25A maximum listed at 20V. Charging capability also says nothing about the cable’s video or data rate. Keep the charging cable and any monitor cable clearly identified in your bag.

Supertiny is the more explicitly documented choice here if you need a published PPS range. That is a documentation advantage, not a measured charging-speed win. A2663’s manual establishes its fixed outputs; we leave its unverified PPS range unknown rather than importing another Anker model’s specification.

Budget, packed fit and drawbacks

Rolling Square lists the US unit at 44.3 × 35 × 35mm and 76.7g. These are manufacturer dimensions, not our measurements. Its EU and UK units have different dimensions and weights. Do not use the US figures for another plug version, or repeat the brand’s smallest-in-the-world claim without a market-wide comparison.

A quick decision rule

Pick the plug region first, match the laptop’s required profile second, and price the complete cable-and-charger kit third. If foldable prongs are essential, confirm them for the exact unit before ordering. If you need a phone and laptop together, use our multiport GaN allocation guide and budget for its reduced per-port power.

We do not rank charging speed or promise a cooler charger. Those conclusions require controlled testing. The choice here rests on documented compatibility and the parts you actually need to carry.
