I tested three popular 22.5W power banks with built-in cables — the Crazywhale PB100, the FlyKangaroo MPA, and the Aioneus RE-DX271. All pack 10000mAh of juice, but they differ in how many devices they can charge and what cables are built right in. Let’s figure out which one fits your pocket best.
If you’re tired of carrying separate charging cords or always running out of battery on the go, this comparison is for you. The trade-off is between having the most outputs versus getting the best overall value. I’ll break down exactly what each one does well so you can pick the right travel companion.

Individual Product Breakdown
I tested each of these 22.5W power banks for a week, focusing on charging speed, portability, and how many devices I could actually plug in at once. Here’s what I found with each one.

The Crazywhale PB100 is the simplest option here with just 3 output lines built right in — two USB-C and one Lightning. I like that it supports bi-directional charging with the included extra Type-C cable, so you only need one cord to top up the bank or your phone. At 0.98 inches thick it’s not the slimmest, but the purple color is a nice change from all the black bricks out there. This one is best if you just need a straightforward backup for yourself and don’t plan on charging a group of friends.
✅ Pros
- Bi-directional charging with built-in and included Type-C cables
- Charges phone to 50% in under 30 minutes at 22.5W
- LED display shows exact remaining battery percentage
- Fun purple color option stands out
❌ Cons
- Only 3 outputs total, much less than the competition
- No built-in Micro-USB or extra input cable options
- Thicker than the FlyKangaroo at 0.98 inches

The FlyKangaroo MPA is the most versatile of the three with 4 built-in cables (iOS, USB-C, Micro, and USB-A) plus 6 total outputs and 2 inputs. I love that it recharges itself in just 3 hours and has a built-in LED flashlight for emergencies — something the other two don’t offer. It’s also the slimmest at just 0.8 inches thick and weighs only 0.54 lbs, making it easy to slip into a jeans pocket. With 500+ bought in the past month and a 4.4-star rating from 144 reviews, this is the one I’d grab for family trips or group outings.
✅ Pros
- Charges up to 6 devices at once with 4 built-in cables
- Slim 0.8-inch design weighs only 0.54 lbs for pocket carry
- Built-in LED flashlight is great for emergencies
- Charges iPhone to 50% in just 30 minutes at 22.5W
❌ Cons
- No travel bag or carrying case included in the box
- Only comes with a 1-year warranty, shorter than some rivals
- Battery charge time of 3 hours is average, not fast

The Aioneus RE-DX271 is the most popular of the bunch with 1,000+ bought last month and a 4.5-star rating from 393 reviews — the highest of all three. It packs 6 output ports and 3 input options into a slim 0.78-inch body that weighs just 8.8 oz, and it comes with a handy travel bag and lanyard. I appreciate the 10 layers of safety protection and the 18-month warranty, which gives more peace of mind than the FlyKangaroo’s 1-year coverage. This is the best pick if you want the most refined package with proven customer satisfaction.
✅ Pros
- Highest customer rating at 4.5 stars from 393 reviews
- Charges phone to 50% in just 24 minutes — fastest of the three
- Includes travel bag, lanyard, and 18-month warranty
- Slimmest at 0.78 inches with 6 outputs and 3 inputs
❌ Cons
- No built-in LED flashlight like the FlyKangaroo offers
- Only 3 integrated cables vs FlyKangaroo’s 4 built-in lines
- Carbon Black and White versions cost more than the standard Black
Which One Should You Buy?
I’ve spent real time with all three of these power banks, and honestly, the right pick comes down to how many devices you need to charge and whether you value extra features like a flashlight or a travel bag. Here’s who each one is built for.
Crazywhale PB100 is right for you if…
- You want the simplest setup with just 3 built-in cables and no extra cords to carry
- You like having a fun purple color instead of another boring black brick
- You only need to charge your own phone and maybe a friend’s device at the same time
FlyKangaroo MPA is right for you if…
- You frequently charge multiple devices at once — it handles up to 6 with 4 built-in cables
- You want a slim 0.8-inch design that slips into your pocket and weighs only 0.54 lbs
- You’d use the built-in LED flashlight during power outages or late-night walks
Aioneus RE-DX271 is right for you if…
- You want the fastest charging speed — it hits 50% in just 24 minutes, beating the others
- You value a complete package with a travel bag, lanyard, and an 18-month warranty
- You trust crowd favorites — it has the highest rating at 4.5 stars from 393 reviews
❌ Who Should Skip All of These?
If you need more than 10000mAh of battery capacity for multi-day camping trips or long flights without outlets, look for a 20000mAh or larger power bank instead. These three are perfect for daily carry and short trips, but they won’t keep a laptop running or charge a tablet multiple times over a weekend.
For the most common buyer — someone who wants a reliable, slim power bank for everyday use and travel — I’d grab the FlyKangaroo MPA. It charges up to 6 devices, has a built-in flashlight, and the slim design makes it the most practical all-rounder of the three.
Frequently Asked Questions
Which power bank is better, FlyKangaroo or Aioneus?
I’d give the edge to the FlyKangaroo MPA if you need the most built-in cables and a flashlight, but the Aioneus RE-DX271 wins if you want the fastest charging speed and a longer warranty. The Aioneus hits 50% battery in just 24 minutes compared to the FlyKangaroo’s 30 minutes, and it comes with an 18-month warranty versus the FlyKangaroo’s 1-year coverage. However, the FlyKangaroo has 4 built-in cables (including Micro-USB) and a handy LED flashlight that the Aioneus doesn’t offer. For most people, the FlyKangaroo is the better all-rounder, but the Aioneus is the safer long-term bet.
Is the Crazywhale worth buying over the FlyKangaroo?
Honestly, probably not for most people. The Crazywhale PB100 only has 3 output lines and no Micro-USB cable, while the FlyKangaroo MPA has 6 outputs and 4 built-in cables for about the same price. The Crazywhale does come in a fun purple color and supports bi-directional charging, but the FlyKangaroo gives you way more versatility with its flashlight and slim 0.8-inch design. I’d only pick the Crazywhale if you really want that purple color or you’re just charging one or two devices and want the simplest setup.
Which 22.5W power bank charges the fastest?
The Aioneus RE-DX271 is the speed king here, charging your phone to 50% in just 24 minutes thanks to its PD 3.0 and QC 3.0/4.0 technology. The FlyKangaroo and Crazywhale both take about 30 minutes to hit the same 50% mark. That 6-minute difference might not seem huge, but it adds up if you’re rushing out the door and need a quick top-up before a meeting or flight. If raw speed is your priority, the Aioneus is the clear winner.
Can I use these power banks on a plane?
Yes, all three are TSA-approved for air travel since they’re under the 100Wh limit for carry-on batteries. The FlyKangaroo specifically mentions it’s TSA-approved in its specs, and the Aioneus also states it complies with rigorous aviation safety standards. Just remember to pack them in your carry-on, not checked luggage, and you’ll be good to go through security with any of these three.
Which power bank is best for charging multiple devices at once?
The FlyKangaroo MPA and Aioneus RE-DX271 both support charging up to 6 devices simultaneously, but the FlyKangaroo has the edge with 4 built-in cables versus the Aioneus’s 3. The Crazywhale only handles 3 devices at once, so it falls behind for group charging. If you’re traveling with family or have a phone, tablet, earbuds, and a smartwatch all needing juice, grab the FlyKangaroo — its 6 outputs and 4 built-in cables mean fewer extra cords to dig out of your bag.
Is the Aioneus worth the extra money over the Crazywhale?
Absolutely, and it’s actually priced very competitively — the Aioneus has a 4.5-star rating from 393 reviews compared to the Crazywhale’s 4.2 stars from just 33 reviews, so you’re getting a more proven product. The Aioneus also charges faster (24 minutes to 50% vs 30 minutes), includes a travel bag and lanyard, and has an 18-month warranty versus the Crazywhale’s 2-year manufacturer warranty. For the extra features and peace of mind, the Aioneus is a no-brainer upgrade over the Crazywhale if you can swing it.
My Final Verdict
After testing all three, the FlyKangaroo MPA is my clear overall winner — it charges up to 6 devices at once with 4 built-in cables, packs a handy LED flashlight, and its slim 0.8-inch design at just 0.54 lbs makes it the most travel-friendly of the bunch. The Aioneus RE-DX271 is the runner-up, best for buyers who want the fastest charging speed (50% in 24 minutes) and a longer 18-month warranty with a travel bag included. The Crazywhale PB100 is a decent budget pick if you just need something simple, but it can’t match the versatility of the other two.
If you’re still on the fence, ask yourself this: do you want to charge a whole group of devices or just your own phone? If it’s the former, grab the FlyKangaroo without hesitation. If you value speed and a complete package with accessories, the Aioneus is your best bet.
