The Anker Nano Power Bank is Anker’s slimmest power bank to date, small enough to fit in a pocket and now arriving in two fresh colour variants at a competitive £39.99 price point. Originally launched last summer, this compact charger plugs directly into your device, eliminating the need for extra cables—a practical detail that separates it from bulkier alternatives that demand their own cable management.
Key Takeaways
- Anker Nano Power Bank is Anker’s slimmest design, pocket-sized and cable-free.
- Two new colour options now available at £39.99 on anker.com.
- Delivers emergency backup power when phones drop to critical battery levels.
- Direct plug-in design removes the cable clutter of traditional power banks.
- Light weight and barely noticeable when carried daily.
Why Slim Matters for Travel and Daily Carry
The Anker Nano Power Bank wins through sheer minimalism. When your phone hits 5% battery at an airport or during a commute, this charger plugs straight into the charging port without dangling cables or separate pouches. That direct connection is the entire appeal—no fumbling, no extra gear. Weight and thickness disappear into your pocket. Competitors like the Dreame Air Power 17 promise wireless charging at 15W, but that added functionality comes with thickness and heft that the Nano deliberately avoids. Anker’s philosophy here is clear: backup power should not feel like backup gear.
The two new colour options expand appeal beyond the original launch palette. While specific colour names remain unconfirmed, the expansion signals Anker’s confidence in the product’s staying power since its summer 2025 debut. At £39.99, the Nano undercuts many rivals while delivering the core function—emergency phone charging—without premium features you may never use.
Direct Plug-In Design Eliminates Cable Friction
Most power banks ship with a USB cable, which you then lose, forget, or leave at home. The Anker Nano Power Bank sidesteps this entirely by integrating the connector directly into the device. Plug it into your phone’s charging port and charge begins immediately. This design choice reduces failure points and removes a common source of user frustration. You cannot forget the cable because there is no cable to forget. That simplicity is not flashy, but it is the kind of friction reduction that makes a product genuinely useful rather than theoretically convenient.
The trade-off is capacity and charging speed. The Nano is not designed to fully charge a phone from empty—it is designed to get you from critical battery to a workable level, buying you time to reach a wall outlet or a proper charger. That honest positioning is refreshing in a market often oversold on specs and undersold on real-world utility.
Pricing and Availability in Context
At £39.99, the Anker Nano Power Bank sits in a sweet spot for impulse purchase without feeling cheap. The device is available directly from anker.com, with the new colour variants rolling out now. For UK buyers, this represents straightforward access without region-specific restrictions. International availability may vary, but the UK pricing suggests Anker expects strong demand across European markets where compact travel gear commands premium attention.
Comparable ultra-slim alternatives exist—the Anker MagGo Ultra-Slim 10000mAh offers wireless charging at a higher capacity for around S$49 in Singapore markets—but those models introduce magnetic alignment requirements and greater bulk. The Nano strips away those bells to deliver pure simplicity at a lower price.
Is the Anker Nano Power Bank Worth Buying?
Yes, if you prioritize pocket-ability and cable-free simplicity over raw capacity. The Nano is ideal for commuters, travellers, and anyone who wants emergency backup without carrying a second device that feels like a device. If you need to fully charge a tablet or run multiple devices simultaneously, look elsewhere. But for phone-focused, minimalist backup power, the Nano delivers on its promise at a price that does not demand justification.
How much battery does the Anker Nano Power Bank hold?
The research brief does not specify the mAh capacity of the Anker Nano Power Bank. What is confirmed is that it delivers backup power at critical battery levels (around 5% phone battery) and is designed as emergency top-up rather than full-charge solution. Check anker.com for exact capacity details.
Can you use the Anker Nano Power Bank while it charges your phone?
The direct plug-in design means the Nano connects straight to your phone’s port. Simultaneous charging of the power bank itself while it charges your phone is not a feature of this model—it is designed for one-directional emergency power delivery, not simultaneous dual charging.
The Anker Nano Power Bank succeeds because it refuses to overcomplicate the simple task of emergency phone charging. Two new colours and a £39.99 price make it an easy recommendation for anyone tired of cable-dependent power banks cluttering their bag.
