The Baseus Picogo AC22 stands out from most budget power banks for one reason: it’s roughly the size of a wireless earbuds case, yet still packs 10,000mAh and 45W fast charging. This Baseus Picogo AC22 review looks at whether that size-to-power ratio holds up once you’re actually using it daily, not just reading the spec sheet.
Baseus Picogo AC22 Specs at a Glance
| Spec | Detail |
|---|---|
| Capacity | 10,000mAh (dual-cell, 72Wh internal rating) |
| Output | Up to 45W via built-in USB-C cable |
| Size | About the size of a wireless earbuds case, roughly 170g |
| Display | Digital percentage readout |
| Recharge Time | Around 2 hours via 30W input |
| Typical Price | ~$30-40 |
Why the Size Actually Matters
Most power banks force a trade-off: small and light, or high-capacity and bulky. The AC22 pushes back on that by using a dual-cell silicon-carbon battery design, which lets it hit a genuinely small footprint without giving up the 45W output that makes it useful for more than just topping off a phone. The built-in USB-C cable is a smart touch too, one less thing to forget when you’re packing for the day.
Where It Runs Warm
Independent testing found the unit generates noticeable warmth during sustained 45W charging sessions, which is worth knowing if you plan to fast-charge a phone or tablet from empty rather than just topping off. Baseus includes a seven-point safety system to manage this, and reviewers note it handles the heat safely, but it’s still a real characteristic of pushing this much output through such a small body.
The built-in cable is also fairly short, since it doubles as a carrying strap. That’s a smart space-saving design, but it does mean you can’t comfortably use your phone while it’s charging in your pocket.
Baseus Picogo AC22 vs. Anker 523
| Factor | Baseus Picogo AC22 | Anker 523 |
|---|---|---|
| Size | Noticeably smaller, earbuds-case-sized | Standard slim power bank size |
| Output | 45W | 20W |
| Built-in Cable | Yes | No |
| Pass-Through Charging | Limited (shared 5V/3A when both ports active) | Not supported |
If pocketability and faster charging matter most, the AC22 pulls ahead. If you want a slightly larger, no-frills option from a more established brand name, the Anker 523 is still a safe, dependable pick.
Who Should Buy the Baseus Picogo AC22
- Commuters and travelers who want the smallest possible footprint without sacrificing real charging speed
- Anyone who wants to skip carrying a separate charging cable
- Buyers who value a digital battery readout over basic LED indicator lights
Who Should Skip It
- Anyone who wants to use their phone comfortably while it’s charging in a pocket, given the short built-in cable
- Buyers planning to charge laptops, since this isn’t rated for that kind of sustained higher-wattage load
- Anyone sensitive to a power bank generating warmth during fast-charge sessions
Frequently Asked Questions
Is the Baseus Picogo AC22 TSA-approved for flights? Yes, at 10,000mAh it falls well under the standard airline watt-hour limits and is safe for carry-on, though you should always confirm current rules with your specific airline before flying.
Does the built-in cable wear out faster than a regular charging cable? It’s built more durably than a standard cable since it doubles as a carrying strap, but like any built-in cable, it can’t be replaced separately if it eventually fails, unlike a detachable cable.
Can the Baseus Picogo AC22 charge a laptop? Not effectively. It’s designed for phones, tablets, and smaller devices; Baseus offers other models in their lineup better suited to laptop charging.
Why does the power bank feel warm while charging? Fitting 45W output into such a compact body generates more heat than a larger, slower power bank would. This is expected behavior with a built-in safety system managing it, not a sign of malfunction.
