Detailed overview: Anker Nano 5000 mAh power bank
The Anker Nano Power Bank (model A1653) is an ultra-compact 5,000 mAh charger built around a single idea: a folding USB-C plug, molded into the body, that flips out and clips directly onto the phone. There is no cable to dig for and nothing separate to carry, since the connector is the charger.
On power, it delivers up to 22.5W through PowerIQ 3.0, enough to charge a phone at a genuinely useful pace: Anker's own testing has an iPhone 15 gaining a meaningful chunk of charge in around 30 minutes on the built-in connector. A second USB-C port sits alongside it, letting you charge a second device, or recharge the pack itself, at the same time. Four LED indicators show the remaining level.
Its 5,000 mAh capacity, about 18 Wh, delivers roughly one full recharge for most current smartphones in practice, the kind of top-up meant to carry a phone through the rest of a busy day rather than a whole weekend. The whole unit weighs about 3.5 ounces (100 g) in a cube-like shape of roughly 3 x 1.5 x 1 inches, small enough to disappear into a jeans or jacket pocket without notice.
Anker builds the shell largely from recycled plastics, and its ActiveShield technology monitors temperature continuously during charging for safety. Sold in several colors on Amazon.com, the Nano A1653 is one of the simplest ways to carry backup power for a phone without ever having to remember a cable.

Comparison
Around $24, this Anker Nano competes with the most popular cable-free 5,000 mAh pocket chargers on Amazon.com, next to searches like "power bank plugs into phone" or "best 5000mAh power bank". Here is how it stacks up against three US alternatives: the Belkin BoostCharge 5K, the Anker Nano Magnetic (its own newer sibling), and the Miady 5,000 mAh twin-pack.
| Criterion | Anker Nano A1653 | Belkin BoostCharge 5K | Anker Nano Magnetic | Miady 5,000 (2-pack) |
|---|---|---|---|---|
| Capacity | 5,000 mAh | 5,000 mAh | 5,000 mAh | 5,000 mAh each |
| Connectivity | Folding USB-C plug + USB-C | USB-C + USB-A | MagSafe wireless + USB-C | USB-A + USB-C |
| Power | 22.5W | ≈ 12W | 15W wireless / 20W USB-C | 12W |
| Observed US price | ≈ $24 | ≈ $22 | ≈ $55 | ≈ $15 for two |
In short, the Nano A1653 stays the fastest cable-free option at its price: no other pack in this range plugs directly into the phone at 22.5W. Anker's own newer Nano Magnetic swaps the folding plug for MagSafe convenience at more than double the price, while the Miady twin-pack wins on raw value if two slower backups beat one fast one. For a minimalist, always-ready pocket charger, the A1653 remains a smart pick.

Video: Review: Anker Nano Power Bank with Built-in Foldable USB-C Connector, 5000 mAh 22.5W - Published on 05/04/2024
Our tester's review: Guillaume Hoarau
This tiny block earns a permanent spot in a coat pocket for one reason: it plugs straight into the phone with no cable to lose. Flip the connector out, clip it onto an iPhone or a USB-C Android phone, and charging starts immediately. At 3.5 ounces you genuinely forget it is there until the phone needs it, and the 5,000 mAh gives a solid single top-up, more than enough to rescue a dying phone before dinner. The 22.5W output is a real step up from the 12W chargers of a few years ago, our test phone gained close to 50% in under 30 minutes. The second USB-C port is a nice extra for earbuds or a smartwatch. Two honest notes from Amazon reviewers: 5,000 mAh is one recharge, not two, and the folding connector sticks out a bit once clipped on, so it is not something you would use one-handed on a crowded train. For an always-there, cable-free emergency top-up, it is hard to beat.
