Earlier this year, Anker discreetly introduced a high-capacity power bank to complement their existing 737 and Prime series. This powerhouse packs a 25,000mAh battery, delivers 165W total charging output, and includes two convenient built-in USB Type-C cables. Priced competitively under $100, today's special offer brings it down to just $89.99—making it ideal for powering gaming handhelds like the Steam Deck, Asus ROG Ally, or Lenovo Legion Go.
Introducing Anker's 25,000mAh 165W Power Bank

Boasting Anker's second-largest capacity in a compact design, this 25,000mAh (95Wh) power bank delivers approximately 76Wh of usable charge (accounting for 80% efficiency). Here's what that means for your devices:
- Fully charges a Steam Deck or ROG Ally (40Wh) twice
- Powers an ROG Ally X (80Wh) once
- Recharges a Nintendo Switch (16Wh) nearly five times
The power bank features one USB-C port, one USB-A port, plus two built-in USB-C cables (one retractable 2.3ft cable and one fixed 1ft lanyard-style cable). With 100W Power Delivery per USB-C port and 165W combined output, it supports fast charging for all current gaming handhelds—including the 100W-capable ROG Ally X.
Like Anker's premium models, this unit includes an informative LCD display showing battery percentage, charging rates, temperature, health status, and cycle count.
TSA-Compliant Design
At 95Wh capacity—just under the TSA's 100Wh limit for carry-on luggage—this power bank meets airline safety regulations (though its substantial size might warrant additional screening). Note that lithium batteries are never permitted in checked baggage.
