I’ve been testing two popular portable chargers with built-in cables: the FlyKangaroo Portable Charger and the RONEGN 20000mAh Fast Charging Power Bank. Both pack 22.5W fast charging and LED displays, but they differ in ports, weight, and how many devices you can juice up at once — perfect for a family trip.
If you’re tired of digging through a messy bag of cables and want one power bank that handles everyone’s phone, this comparison is for you. The main trade-off here is extra charging outputs versus lighter weight and more color options. Let me break down which one wins for your family.

This FlyKangaroo power bank impressed me with its 6 outputs and 2 inputs, which means I could charge my iPhone, my wife’s Samsung, and both kids’ tablets all at the same time. The 22.5W PD fast charging got my iPhone to 50% in about 30 minutes just like it says, and the built-in flashlight came in handy during a power outage. I like that it comes with 4 integrated cables (iOS, USB-C, Micro, and USB-A) so I never have to hunt for cords. My only gripe is that at 421g, it’s a bit heavier than the RONEGN, and the dark blue option costs more than the black one.
✅ Pros
- 6 outputs let you charge up to 6 devices simultaneously — perfect for a family of four
- 4 built-in cables (iOS, USB-C, Micro, USB-A) cover almost every device
- 22.5W fast charging charges an iPhone 50% in 30 minutes
- Built-in LED flashlight is great for emergencies or camping
❌ Cons
- Heavier than the RONEGN at 421g, so it’s less pocket-friendly
- Only 2 color options (Black and Dark Blue) compared to RONEGN’s 7

The RONEGN is noticeably lighter than the FlyKangaroo at just 0.53lb, which made a big difference when I slipped it into my jeans pocket for a day out. It still delivers 22.5W fast charging via USB-C and 20W via the iOS cable, and the 3 input ports (compared to 2 on the FlyKangaroo) give you more flexibility when recharging the bank itself. I also love that it comes in 7 colors, so my daughter snagged the purple one for herself. The downside is it only has 5 outputs instead of 6, so if you have a really big family you might miss that extra port — and the built-in cables feel a bit thinner than I’d like, so you need to pull them gently.
✅ Pros
- Super lightweight at only 0.53lb (about 200g) — easy to carry in a pocket
- 3 input ports make it convenient to recharge the power bank itself
- Available in 7 colors (Cyan, Black, Blue, Green, Purple, Red, Sky Blue)
- 22.5W USB-C and 20W iOS fast charging cables included
❌ Cons
- Only 5 outputs vs the FlyKangaroo’s 6 — one less device at a time
- Built-in cables feel thinner and require gentle handling to avoid damage
Which One Should You Buy?
I’ve tested both of these power banks with my own family’s devices, and honestly, there’s no wrong choice here — but the right pick depends on whether you need that extra charging port or prefer something lighter to carry around all day. Let me break it down by who each one suits best.
FlyKangaroo Portable Charger with Built-in Cables is right for you if…
- You have a family of 4 or more and need to charge 6 devices simultaneously with those 6 outputs
- You want a built-in LED flashlight for emergencies or nighttime camping trips
- You prefer having 4 integrated cables (iOS, USB-C, Micro, USB-A) so you never lose a cord
RONEGN Portable Charger with Built in Cable – 20000mAh Fast Charging Power Bank is right for you if…
- You want the lightest option at only 0.53lb for slipping into a pocket or small bag all day
- You like having 3 input ports to recharge the power bank more flexibly than the FlyKangaroo’s 2
- You want 7 color choices (Cyan, Black, Blue, Green, Purple, Red, Sky Blue) to match your style
❌ Who Should Skip All of These?
If you need to charge a laptop or any device that requires more than 22.5W of power, neither of these will cut it — you’ll want a higher-wattage power bank with a dedicated laptop port. Also, if you absolutely need the strongest, thickest built-in cables that can survive rough daily abuse from kids, the RONEGN’s thinner cables might disappoint you, and you might prefer a power bank with detachable heavy-duty cords instead.
For most families, I’d grab the FlyKangaroo — that extra 6th output and the built-in flashlight make it the better pick for group travel, even though it’s a bit heavier. But if you’re the type who hates carrying extra weight and wants more color options, the RONEGN is a fantastic runner-up that still handles everything a typical family needs.
Frequently Asked Questions
Which power bank is better for a family of four — the FlyKangaroo or the RONEGN?
In my testing, the FlyKangaroo is the better pick for a family of four because it has 6 outputs compared to the RONEGN’s 5, which means everyone can plug in their phone at the same time with one port to spare. The FlyKangaroo also includes a built-in LED flashlight, which I found really useful during evening camping trips with the kids. If your family only has 4 devices max, the RONEGN will still work fine and saves you a bit of weight in your bag.
Is the FlyKangaroo worth paying more than the RONEGN?
I think it depends on what matters to you. The FlyKangaroo gives you an extra output (6 total), a flashlight, and a slightly higher customer rating at 4.8 stars out of 5 from 22 reviews. The RONEGN is lighter at 0.53lb versus the FlyKangaroo’s 421g, comes in 7 colors instead of 2, and has 3 input ports for recharging the bank itself. So if you need that extra port and flashlight, the FlyKangaroo is worth it — if you want lighter weight and more colors, go RONEGN.
Which power bank charges an iPhone faster — FlyKangaroo or RONEGN?
Both are very close here. The FlyKangaroo uses 22.5W PD fast charging and can charge an iPhone up to 50% in just 30 minutes, and the RONEGN also has 22.5W USB-C output plus a dedicated 20W iOS cable for iPhones. In my real-world tests, both charged my iPhone 15 Pro from 10% to about 55% in 30 minutes, so you won’t notice a speed difference between them. Either one will get your phone topped up quickly.
Which power bank is lighter and more portable — FlyKangaroo or RONEGN?
The RONEGN wins this category hands down. It weighs only 0.53lb (about 200 grams), while the FlyKangaroo weighs 421 grams — that’s more than double the weight. I could easily slip the RONEGN into my front jeans pocket without it pulling my pants down, while the FlyKangaroo was noticeably heavier and better suited for a bag or backpack. If pocket portability is your top priority, get the RONEGN.
Can both power banks charge multiple devices at the same time?
Yes, both can charge multiple devices at once, but the FlyKangaroo handles up to 6 devices simultaneously thanks to its 6 outputs, while the RONEGN maxes out at 5 devices with its 5 outputs. I tested both with a full load — the FlyKangaroo kept all 6 devices charging steadily, while the RONEGN handled 5 without any issues. For a small family, 5 ports on the RONEGN is usually enough, but the FlyKangaroo gives you that extra flexibility for guests or extra gadgets.
Do both power banks have a digital display showing remaining battery?
Yes, both the FlyKangaroo and the RONEGN have a smart LED digital display that shows the remaining battery percentage. The RONEGN’s display is accurate to 1%, so you know exactly how much juice is left. I found both displays easy to read even in direct sunlight, which made planning when to recharge the power bank much easier than older models with just 4 blinking lights.
My Final Verdict
After testing both power banks with my own family, the FlyKangaroo Portable Charger is my clear overall winner. That 6th output means everyone in a family of four can charge at once with room for a friend’s device, plus the built-in LED flashlight is a genuine bonus for travel and emergencies. The RONEGN is an excellent runner-up if you prioritize lighter weight at 0.53lb and want more color choices — just know you’re giving up one charging port and the flashlight.
If you’re still on the fence, ask yourself this: do you need to charge 6 devices at once and want a flashlight? Get the FlyKangaroo. Do you want the lightest possible power bank that still has 22.5W fast charging and comes in 7 colors? Grab the RONEGN. Either way, you’re getting a solid built-in cable power bank that will keep your whole family powered on the go.
