How to Choose a Power Bank in 2026: MagGo, Prime & Nano Explained

Not all power banks are equal. The right one depends on what you charge, how fast you need it, and whether you want it to snap magnetically to your phone. Here is how to choose in 2026, with real Anker picks for each use case.

The three numbers that matter

• Capacity (mAh): 5,000mAh is one phone top-up; 10,000mAh is roughly two; 20,000mAh+ covers a laptop or a weekend.
• Output (W): 20–30W fast-charges a phone; 65W+ is needed for laptops.
• Ports & cables: built-in cables save you from carrying extras; MagGo models attach magnetically for cable-free phone charging.

Best magnetic phone charger: Anker MagGo (10K)

The Anker MagGo Power Bank (10K) at $89.99 is Qi2-certified for 15W magnetic wireless charging and has a built-in stand—ideal for iPhone users who hate cables. For the slimmest option, the Anker 621 Magnetic Battery (MagGo) at $42.99 is a great low-cost entry.

Best everyday power bank: Anker Nano (10K, 45W)

The Anker Nano Power Bank (10K, 45W) at $59.99 has a built-in retractable USB-C cable, so there is nothing extra to carry, and 45W is enough to fast-charge most phones and even small laptops.

Best for laptops and travel

For all-day power, the Anker 737 Power Bank (PowerCore 24K) at $109.99 delivers 140W—enough to fast-charge a MacBook. Need more? The Anker Prime Power Bank (20K, 200W) at $139.99 and the Anker Laptop Power Bank (25K, 165W) at $119.99 are built for multiple laptops and long trips.
