We’ve reviewed the Anker 523, the Baseus Picogo AC22, and the INIU 20,000mAh individually on this site, and each one is genuinely a solid pick. The question we keep getting isn’t “is this one good,” it’s “which one fits me.” Here’s a direct, side-by-side answer instead of three separate reviews you have to piece together yourself.
The Quick Answer
- Want the smallest possible size? Baseus Picogo AC22
- Want a dependable, no-frills option from an established brand? Anker 523
- Need multi-day power or plan to charge a laptop too? INIU 20,000mAh

If You Just Want One Phone Charge a Day
The Anker 523 is the safest, most boring-in-a-good-way choice. It won’t win on speed or efficiency compared to the other two, but Anker’s brand reliability and safety systems make it a low-risk pick if you just want something that works without thinking about it.
If You Want It to Basically Disappear in Your Pocket
The Baseus Picogo AC22 is built specifically for this. It’s roughly the size of a wireless earbuds case, includes a built-in cable so you’re never caught without one, and still delivers real 45W speed despite the tiny footprint. The trade-off is it runs warm under sustained fast charging and the built-in cable is short.
If You Need More Than a Phone Charge
The INIU 20,000mAh is the only one of the three built for real multi-day use or charging something bigger than a phone, like a tablet or laptop. Independent testing rated it as one of the more efficient options in its capacity class, meaning less wasted power for the weight you’re carrying. The trade-off is obvious: it’s noticeably heavier than the other two, so it’s not the pick for minimalist daily carry.
What We’d Actually Recommend for Most People
If you’re not sure which category you fall into, here’s the honest default: most people only need one full phone charge between outlets, which means the Anker 523 or Baseus Picogo AC22 cover 90% of real-world use. Only reach for the INIU’s extra capacity if you know you’ll actually use it, since carrying double the weight for power you don’t need isn’t a real advantage.

Frequently Asked Questions
Is a more expensive power bank always better? Not necessarily. Price differences here mostly reflect capacity and extra features like built-in cables, not raw quality. All three are legitimate, safety-certified options from established brands.
Do I need 45W output, or is 20W enough? 20W is enough for topping off a phone at a normal pace. 45W matters more if you want faster charging or plan to charge larger devices like tablets, where higher wattage meaningfully cuts charging time.
Can any of these three charge a laptop? Only the INIU 20,000mAh is realistically suited for laptop charging, and even then only for lighter laptops like a MacBook Air, not high-power gaming laptops.
Which of these three is best for air travel? All three fall well within standard airline watt-hour limits for carry-on power banks, though you should always confirm current rules with your specific airline before flying.
