round half a kilogram in your bag: that is what it now weighs to ensure you never forget your charging cable again. Baseus has launched the PicoGo AR11 power bank in China, packing a 20,000 mAh battery for 299 yuan (roughly $45). The main appeal here is not raw wattage, but sheer everyday convenience: eliminating the need to fish a tangled nest of cords out of your backpack.
Built-in retractable cables
The chassis features a built-in 80 cm retractable USB-C cable that works like a tape measure. A second 25 cm cord is detachable and doubles as a wrist strap. Standard USB-C and USB-A ports are also included in case you need to power someone else's device.
In single-port mode, either the built-in cable or the standalone USB-C port delivers a full 100W of power—more than enough to fast-charge a MacBook Air or a compact Windows ultrabook without lugging around the factory power brick.
Inside, it houses four 5,000 mAh lithium-ion cells with an operating voltage of 14.6V.
The power bank itself recharges at up to 65W, while its rated energy capacity of 73 Wh stays well within airline carry-on limits. A digital display on the front panel shows the exact battery percentage and real-time power output.
Power distribution and potential weak spots
When charging a laptop and a phone simultaneously via two USB-C outputs, power splits cleanly into 65W + 35W. If you plug into all three ports, the built-in retractable cord reserves 65W, while the remaining ports share a modest 15W. A trickle-charging mode for smartwatches and earbuds is also supported.
The power bank supports PPS, USB PD, and Quick Charge protocols out of the box, with body dimensions measuring 136 × 56 × 49.5 mm. The main caveat with the PicoGo AR11 is purely mechanical: spring-loaded retractable cables rarely survive years of heavy daily use, and if the built-in cord wears out, you are left carrying a regular, bulky brick. On grey-market channels and international marketplaces, expect pricing to climb toward $60–$70, but even with that markup, it remains one of the most practical travel companions for laptop users willing to trade long-term durability for a clutter-free bag.
