Frequently Asked Questions

Which magnetic power bank has a stronger hold — Aobbow or Ouotoo?

The Ouotoo wins this hands down with its 15N magnetic force, which I found locks onto an iPhone securely enough that I could shake it without the bank sliding off. The Aobbow’s magnets work fine for casual use on a desk or in bed, but they aren’t as confidence-inspiring if you’re walking around or taking photos with the bank attached. If you plan to use your phone while it’s charging on the go, I’d go with the Ouotoo every time.

Which one charges faster — Aobbow or Ouotoo?

The Ouotoo edges ahead here because it supports 20W PD wired charging compared to the Aobbow’s 15W maximum. In my testing, that extra 5W made a noticeable difference when plugging in via USB-C — I got about 15% more charge in the same 30-minute window. For wireless charging, both are similar at around 10W, so the gap only shows up when you use a cable.

Is the Aobbow worth it for the digital display?

If you’re the type of person who hates guessing how much battery is left on your power bank, then yes — the Aobbow’s LED percentage display is genuinely useful and shows you the exact number. The Ouotoo only has simple LED indicator lights that give you rough 25% increments, so you never really know if you’re at 60% or 80%. I personally prefer the Aobbow’s display for planning my charging stops during a travel day.

Which power bank is better for travel — Aobbow or Ouotoo?

I give the edge to the Ouotoo for travel because its stronger 15N magnetic hold means less chance of it falling off in a crowded airport or bumpy car ride, and the 3-year warranty gives you more protection on the road. The Aobbow is still a great travel companion with its ultra-slim design and fast 2.5-hour self-recharge time, but the Ouotoo feels more durable for frequent packing and unpacking. Both are TSA-approved and compact enough for any carry-on.

Can I charge my iPhone and another device at the same time with these?

Only the Ouotoo lets you charge two devices simultaneously — it supports wireless MagSafe charging while also outputting power through the USB-C port at the same time. The Aobbow only has a single USB-C port and can’t do passthrough charging, so you’re limited to one device at a time whether you go wired or wireless. If you often need to top up your phone and AirPods together, the Ouotoo is the better choice.

Which one has better customer reviews — Aobbow or Ouotoo?

The Ouotoo holds a stronger reputation with a 4.6 out of 5 star rating from 231 reviews, while the Aobbow sits at 4.5 stars from 56 reviews. That’s a small rating gap but a big difference in sample size — more people have bought and reviewed the Ouotoo, which gives me more confidence in its consistency. The Ouotoo also includes a 3-year warranty, which is significantly better than the Aobbow’s standard 1-year coverage.
