LENOVO GO USB-C POWER BANK 20000 65W

The Lenovo Go USB-C Laptop Power Bank (40ALLG2WWW) is a 20,000mAh / 74Wh high-capacity portable power solution engineered specifically for laptop users, remote workers, and frequent travellers — delivering 65W USB-C Power Delivery for full-speed laptop charging, an integrated built-in USB-C cable for cable-free convenience, a second USB-C port for additional devices, an 18W USB-A fast charge port, simultaneous three-device charging, pass-through charging, and a full recharge in under 3 hours. The Lenovo Go Power Bank is the purpose-built portable charging companion for ThinkPad, IdeaPad, Yoga, LOQ, and all USB-C laptop users.

20,000mAh / 74Wh — HIGH-CAPACITY LAPTOP-GRADE POWER RESERVE

The 20,000mAh lithium-ion polymer cell delivers 74Wh of stored energy — providing substantial charging capacity for demanding laptop users:

- Lenovo ThinkPad X1 Carbon (57Wh): approximately 1 full charge + partial second

- Lenovo Yoga 7 (71Wh): nearly 1 full charge from depleted

- MacBook Air M2 (52.6Wh): approximately 1.2 full charges

- MacBook Pro 14" (70Wh): approximately 0.9 full charge

- iPhone 16 Pro Max (4,685mAh): approximately 3-4 full charges

- Samsung Galaxy S25 Ultra (5,000mAh): approximately 3 full charges

The 20,000mAh capacity ensures that a single full charge of the power bank provides substantial laptop runtime extension — eliminating the dependency on wall sockets during travel, flights, meetings, and outdoor work sessions.

65W USB-C POWER DELIVERY — FULL-SPEED LAPTOP CHARGING

The primary USB-C output delivers 65W Power Delivery at 20V/3.25A — the sufficient charging rate for the vast majority of USB-C laptops and MacBooks. Compatible with PD 3.0 and all standard USB-C Power Delivery protocols, the 65W output charges ThinkPad, IdeaPad, Yoga, MacBook Air, MacBook Pro 13"/14" (65W model), Dell XPS 13, ASUS ZenBook, and virtually all USB-C laptops at their rated charging speed. For laptops with higher wattage requirements (MacBook Pro 16" at 96W, gaming laptops at 100W+), the power bank charges at a reduced but functional rate.

INTEGRATED USB-C CABLE — CABLE-FREE CONVENIENCE

The 435mm built-in USB-C cable is permanently attached to the power bank — providing immediate charging capability without carrying or locating a separate USB-C cable. The integrated cable is the primary charging output, connecting directly to the laptop's USB-C port for plug-and-go charging whenever needed. For users who need more cable length, the second USB-C female port accommodates any standard USB-C cable at the same 65W maximum output.

DUAL USB-C + USB-A — THREE-PORT SIMULTANEOUS CHARGING

Three output ports enable simultaneous charging of up to three devices:

- Integrated USB-C cable: 65W max — for the primary laptop

- USB-C female port: 65W max — for a second laptop, tablet, or USB-C device using your own cable

- USB-A port: 18W max (12V/1.5A) — for smartphones, earbuds, smartwatches, and USB-A accessories

Note: when multiple ports are in use simultaneously, available power is distributed between active ports — peak 65W is available on USB-C when charging alone.

PASS-THROUGH CHARGING — CHARGE THE BANK AND DEVICES SIMULTANEOUSLY

Pass-through charging enables the power bank to recharge itself via the USB-C input port while simultaneously charging a connected laptop through the integrated cable — the power bank, laptop, and an additional device can all charge from a single wall socket through the power bank simultaneously. Eliminates the need for multiple wall socket outlets in hotel rooms, airport lounges, and shared workspaces.

FULL RECHARGE IN UNDER 3 HOURS

The power bank accepts up to 100W input via USB-C (20V/5A) — fully recharging the 74Wh cell in under 3 hours when connected to a 65W or higher USB-C PD adapter. A 65W adapter (such as the Lenovo 65W USB-C GaN charger or UGREEN CD226 USB-C output) charges the power bank at maximum rate.

4 LED BATTERY LEVEL INDICATORS

Four LEDs on the power bank body display remaining battery level at a glance — each LED represents approximately 25% capacity, providing immediate visual confirmation of available power without a connected device or app.

MULTI-LAYER SAFETY PROTECTION

- Overheat protection: monitors internal temperature and limits charging current under thermal stress

- Overcurrent protection: prevents current delivery above safe thresholds

- Overvoltage protection: guards against input voltage spikes

- Overcharge protection: stops charging once full capacity is reached

Standards compliance: CB, cTUVus, CEC, UN38.3 — independently certified for international travel safety requirements. UN38.3 certification specifically validates battery safety for air travel carriage.
