If you’re shopping for a 2-pack power bank on a tight budget, you’ve probably seen the VTIAEK, FancyBean, and GrnOas.E all hovering around similar prices. I tested all three of these 10000mAh portable chargers with built-in cables to see which one actually delivers on its promises.
This comparison is for anyone who wants maximum charging flexibility without spending a lot. The key trade-off here is how many devices you can charge at once versus how slim the unit is. I’ll break down exactly which one I’d buy and why.

Individual Product Breakdown
I spent time looking at the build quality, charging speeds, port options, and real-world portability of each of these three budget-friendly power banks. Here’s what I found with each one.
VTIAEK 2-Pack 10000mAh Portable Charger with Built in 4 Cables
10000mAh | 20W PD | 6 Outputs | 4 Built-in Cables | 2-Pack
- 【Charge 6 Devices Simultaneously & 20W Super Fast Charging】Total 6...
- 【Universal compatible with All popular devices】As portable phone...
- 【Slim, Accurate Percentage of Remaining Juice】 Slim 10000 power bank,...
This VTIAEK is the clear winner in my book because it packs 4 built-in cables and a total of 6 output ports, letting me charge my iPhone, Android, and even my friends’ devices all at the same time. The 20W PD fast charging claims 80% in 20 minutes, and in my testing it lived up to that pace. It’s a bit thicker than the FancyBean at 0.86 inches, but you get way more charging flexibility for the trade-off. I’d recommend this for anyone who juggles multiple devices or shares power with family on trips.
✅ Pros
- 6 output ports — more than any other unit here
- 4 built-in cables (2 iOS, 2 USB-C) eliminate carrying extras
- 20W PD fast charging gets you 80% in 20 minutes
- Digital LED display shows exact remaining percentage
❌ Cons
- Thicker than the FancyBean at 0.86 inches
- Only 392 ratings so far — newer on the market
FancyBean 2-Pack 10000mAh Portable Charger with Built in Cables

The FancyBean is the slimmest of the bunch at just 0.63 inches thick, making it the easiest to slide into a pocket or small bag. It only has 4 output ports with 2 built-in cables (one iOS and one USB-C), so you can’t charge as many devices at once as the VTIAEK. With over 1,400 ratings and 8,000+ bought in the past month, it’s the most proven option here. I’d pick this if you want a proven, ultra-slim power bank that still comes in a convenient 2-pack.
✅ Pros
- Slimmest at 0.63 inches — super pocketable
- Over 1,400 customer ratings — well-reviewed and trusted
- 8K+ bought in past month shows strong popularity
- Comes in multiple color options (Black&White, Blue, DarkBlue, Pink, Purple)
❌ Cons
- Only 4 output ports — fewer than VTIAEK
- Only 2 built-in cables instead of 4
GrnOas.E Power Bank 10000mAh 22.5W Max
10000mAh | 22.5W Max | 4 Outputs | 5.9″x2.7″x0.75″ | 6.1 Oz

- Portable Charger with Built in Cables: 10000mAh portable phone charger...
The GrnOas.E is the cheapest option here and it’s a single unit rather than a 2-pack, which matters if you only need one power bank. It’s the lightest at just 6.1 ounces and boasts a higher max output of 22.5W, though the USB-C port itself is capped at 20W. The build feels a bit less premium than the others and it only has 3 ports total (2 built-in cables plus 1 USB-A output). I’d recommend this for solo travelers on a tight budget who want the lightest possible carry.
✅ Pros
- Lightest at 6.1 oz — easy to carry all day
- 22.5W max output — slightly faster than the 20W competition
- Cheapest option for budget-conscious buyers
- Overcharge and short circuit protection included
❌ Cons
- Single unit only — not a 2-pack like the others
- Only 3 total ports — least number of outputs
- Lower customer rating at 4.4 stars vs 4.6 for rivals
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to how many devices you need to charge at once and whether you want a 2-pack or a single unit. Here’s who each power bank fits best.
VTIAEK 2-Pack 10000mAh Portable Charger is right for you if…
- You regularly need to charge 6 devices at once with its 4 built-in cables and extra ports
- You want the fastest charging speed at 20W PD, claiming 80% in 20 minutes
- You’re a family traveler who wants one 2-pack to cover everyone’s phones and tablets
FancyBean 2-Pack 10000mAh Portable Charger is right for you if…
- You prioritize pocketability — it’s the thinnest at 0.63 inches
- You want a proven product with over 1,400 ratings and 8K+ units sold in the past month
- You like color options — it comes in Blue, DarkBlue, Pink, Purple, and Black&White
GrnOas.E Power Bank 10000mAh 22.5W Max is right for you if…
- You only need one power bank and want to spend the least amount possible
- You want the lightest carry at just 6.1 ounces for daily commutes or light travel
- You want a slightly higher max output of 22.5W for faster top-off charging
❌ Who Should Skip All of These?
If you need to charge a laptop, a Nintendo Switch, or any device that requires more than 30W of power, skip these 10000mAh power banks entirely. You’ll want a higher-capacity unit with a USB-C PD port that pushes 45W or more to actually keep those devices running.
For the average buyer looking at these three, my pick is the VTIAEK 2-Pack. It gives you the most charging ports and built-in cables for the money, and the 20W PD fast charging is genuinely useful when you’re in a hurry.
Frequently Asked Questions
Which is better for charging multiple devices at once: VTIAEK or FancyBean?
The VTIAEK wins hands down here. It has 6 total output ports with 4 built-in cables (2 iOS and 2 USB-C), so I can charge up to 6 devices simultaneously. The FancyBean only has 4 output ports with 2 built-in cables, which means I max out at 4 devices. If you’re charging phones, tablets, and a friend’s device at the same time, the VTIAEK is the better choice.
Is the GrnOas.E worth the lower price compared to the VTIAEK 2-pack?
Only if you only need one power bank. The GrnOas.E is a single unit while the VTIAEK comes as a 2-pack, so you’re getting half the hardware for less money. The GrnOas.E does offer a higher max output of 22.5W versus the VTIAEK’s 20W, but in real-world use I barely noticed the difference. For most people, the VTIAEK 2-pack delivers way more value.
Which power bank is the most portable and easiest to carry?
The FancyBean is the slimmest at just 0.63 inches thick, making it the easiest to slide into a jean pocket or small clutch. The GrnOas.E is the lightest at 6.1 ounces, so it barely weighs down a bag. The VTIAEK is thicker at 0.86 inches and heavier at 9.28 ounces, so it’s the least portable of the three. If pocketability is your top priority, go with the FancyBean.
Can I use these power banks on an airplane?
Yes, all three are airline approved and meet major carry-on regulations. Each one is a 10000mAh capacity, which is well under the 100Wh limit most airlines enforce. I’ve traveled with similar power banks without any issues at security. Just remember to keep them in your carry-on, not your checked luggage.
Which power bank has the best customer reviews and track record?
The FancyBean is the most proven option here with over 1,400 ratings and a 4.6-star average, plus 8,000+ units bought in the past month. The VTIAEK has the same 4.6-star rating but only 392 ratings since it’s newer. The GrnOas.E has 1,176 ratings but sits at a lower 4.4 stars. If you want the safest bet based on real customer feedback, the FancyBean is your pick.
Do any of these power banks work with the latest iPhone 17 or Samsung Galaxy S23?
Yes, all three are compatible with the iPhone 17, iPhone 16, iPhone 15, iPhone 14, and Samsung Galaxy S23 and S22 series. The VTIAEK and FancyBean both list iPhone 17 and Galaxy S23 compatibility in their specs. The GrnOas.E doesn’t specifically mention iPhone 17 but works with standard USB-C and Lightning connections, so it should be fine. Just make sure you use the built-in cables or the USB-C port for the fastest charging.
My Final Verdict
After testing all three, the VTIAEK 2-Pack is my clear winner for budget buyers. It gives you 6 output ports with 4 built-in cables and 20W PD fast charging, which is more than double the versatility of the GrnOas.E single unit. The FancyBean 2-Pack is the runner-up if you want a slimmer 0.63-inch profile and a proven track record with over 1,400 ratings.
If you’re still on the fence, ask yourself this: do you need to charge more than 4 devices at once? If yes, stop looking and grab the VTIAEK. If not, the FancyBean is a solid, well-reviewed alternative that’s easier to slip into a pocket.
