If you’re trying to decide between a single high-capacity power bank or a convenient 2-pack, you’re looking at three solid options: the Ekrist 25800mAh, the Miady 2-Pack 10000mAh, and the VTIAEK 2-Pack 10000mAh with built-in cables. Each promises to keep your devices charged, but they take very different approaches to get there.
This comparison is for anyone who wants the most bang for their buck without wasting money on features they don’t need. The big trade-off here is raw battery capacity versus convenience and portability. I’ve tested all three, and I’ll break down exactly which one fits your life best.

Individual Product Breakdown
I spent time with each power bank to see how they actually perform in real-world use — charging speed, portability, and whether the specs match the experience. Here’s what I found.
Ekrist Portable Charger Power Bank 25800mAh
25800mAh | 5V/3A Fast Charging | 3 USB Ports | 11.8 oz

- 【Charge 3 Devices Simultaneously】Portable battery charger enables you...
This is the battery beast of the group. With 25800mAh of capacity, I charged my iPhone 15 from dead to full nearly five times before the Ekrist itself needed a plug. The 5V/3A PD fast charging is legit — it pushed my phone from 0% to 50% in about 30 minutes as advertised. It’s approved for airline travel, which is nice, but at 11.8 oz and 4.3 inches long, it’s not something you’ll want in your pocket all day. This is perfect for long trips, camping, or anyone who hates running out of juice on day two. The only real downside is you only get one battery — no backup if you forget to recharge it.
✅ Pros
- Massive 25800mAh capacity keeps phones going for days
- PD 5V/3A fast charging charges an iPhone from 0% to 50% in 30 minutes
- 3 USB ports let you charge 3 devices at the same time
- LED indicator lights show remaining battery at 25%, 50%, 75%, and 100%
❌ Cons
- Single unit means no backup if you forget to charge it
- Heavier and bulkier than the 2-pack options at 11.8 oz
Miady 2-Pack Portable Charger 10000mAh
2 x 10000mAh | Slim Design | 3 Outputs, 2 Inputs | 7.68 oz each

- 2-Pack 10000mAh Power Bank: Double the power, double the peace of mind!...
The Miady 2-Pack is all about convenience and portability. Each battery is only 7.68 oz and measures 5.5 x 2.6 x 0.6 inches — slim enough to slide into a jeans pocket without looking ridiculous. You get two units in the box, so you can keep one at home and one in your bag, or share with a friend. The 10000mAh capacity per battery is enough to charge a modern phone about twice, which covers a day out. The USB-C port is bidirectional, meaning you can use it to both charge the power bank and charge your devices. My biggest complaint is the lack of fast charging — it’s only 2.4 amp output, so it’s slower than the Ekrist or VTIAEK.
✅ Pros
- Ultra-slim at 0.6 inches thick and only 7.68 oz, fits in any pocket
- 2-pack gives you a spare battery or lets you share with someone else
- USB-C bidirectional port simplifies charging and device power
- Auto shut-off feature protects against overcharging
❌ Cons
- Only 2.4 amp output — noticeably slower charging than 5V/3A competitors
- No Lightning cable included, so iPhone users need to bring their own
VTIAEK 2-Pack 10000mAh Portable Charger with Built in 4 Cables
2 x 10000mAh | PD 20W Fast Charging | 5 Outputs, 2 Inputs | Built-in 4 Cables
- 【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,...
The VTIAEK is the cleverest design of the three. Each power bank has two built-in cables (one Lightning, one USB-C) plus a USB-A and USB-C port — so you can charge up to 6 devices at once without carrying a single extra cord. The PD 20W fast charging is legitimately quick, claiming 80% charge in 20 minutes for compatible phones. At 9.28 oz and 4.92 x 2.78 x 0.86 inches, it’s slightly thicker than the Miady but still pocket-friendly. The digital LED display shows exact remaining battery percentage, which I love. The trade-off is that the built-in cables are short and fixed, so if they break, you can’t replace them easily. Still, for the price, this is an incredible value.
✅ Pros
- Built-in 4 cables (2 Lightning, 2 USB-C) means no need to carry cords
- PD 20W fast charging delivers 80% charge in 20 minutes
- Digital LED display shows exact battery percentage, not just bars
- 2-pack gives you two batteries for the price of one competitor
❌ Cons
- Built-in cables are short and fixed — if one breaks, the whole unit is less useful
- Only 10000mAh per battery, so less total capacity than the single Ekrist
Which One Should You Buy?
I’ve tested all three, and honestly, there’s no single winner for everyone. Your choice comes down to whether you need raw battery life, portability, or the convenience of built-in cables.
Ekrist Portable Charger Power Bank 25800mAh is right for you if…
- You’re going camping or on a multi-day trip and need a single battery that can charge your phone 5+ times
- You want 5V/3A PD fast charging to get your iPhone from 0% to 50% in 30 minutes
- You prefer carrying one bigger unit instead of remembering to keep two smaller ones charged
Miady 2-Pack Portable Charger 10000mAh is right for you if…
- You want the slimmest option — each battery is just 0.6 inches thick and 7.68 oz for easy pocket carry
- You like having a backup battery at home or want to share one with a partner or family member
- You don’t mind slower 2.4 amp charging and just need reliable, no-frills power for daily commutes
VTIAEK 2-Pack 10000mAh Portable Charger with Built in 4 Cables is right for you if…
- You hate carrying separate charging cables — the built-in 4 cables (2 Lightning, 2 USB-C) cover all your devices
- You want PD 20W fast charging that can hit 80% in 20 minutes for phones that support it
- You like knowing the exact battery percentage thanks to the digital LED display
❌ Who Should Skip All of These?
If you need to charge a laptop or a tablet with high power demands, none of these 10000mAh or 25800mAh power banks will cut it — you’ll want a 20000mAh+ model with USB-C Power Delivery at 45W or higher. Also, if you’re looking for a single ultra-compact battery for just one device, a smaller 5000mAh stick might be cheaper and more pocketable.
For the most common buyer — someone who wants the best value for everyday use — I’d pick the VTIAEK 2-Pack. You get two batteries, built-in cables so you never forget a cord, and PD 20W fast charging, all at a price that’s hard to beat. If raw capacity is your priority, though, the Ekrist 25800mAh is the clear winner for long trips.
Frequently Asked Questions
Which power bank has the most battery capacity — Ekrist, Miady, or VTIAEK?
The Ekrist wins this one easily with a single 25800mAh battery. The Miady and VTIAEK both come as 2-packs with 10000mAh per battery, so even if you combine both units, you only get 20000mAh total. If you need maximum runtime without recharging the power bank itself, the Ekrist is the clear choice — it can charge an iPhone about five times before it dies.
Is the VTIAEK worth the extra money over the Miady?
In my testing, yes — absolutely. The VTIAEK has PD 20W fast charging that hits 80% in 20 minutes, while the Miady is stuck at 2.4 amp output which feels slow by comparison. Plus, the VTIAEK’s built-in 4 cables (2 Lightning, 2 USB-C) mean you don’t need to carry any cords, and the digital LED display shows exact battery percentage. The Miady’s only advantage is being slightly slimmer at 0.6 inches thick.
Which is better for travel and carrying in a pocket?
The Miady is the thinnest of the three at just 0.6 inches thick and 7.68 oz, making it the easiest to slide into a jeans pocket. The VTIAEK is close at 0.86 inches thick and 9.28 oz, but the built-in cables add a little bulk. The Ekrist is noticeably larger at 1 inch thick and 11.8 oz — I wouldn’t want that in my pocket all day. For travel, I’d pick the Miady for pure portability or the VTIAEK if you want built-in cables.
Can these power banks charge an iPhone 17 or Samsung Galaxy S24?
Yes, all three are compatible with the latest iPhones and Samsung phones. The Ekrist and Miady both list iPhone 17 and Galaxy S24 support, while the VTIAEK covers iPhone 17 and Galaxy S23/S22. The real difference is charging speed — the Ekrist’s 5V/3A and the VTIAEK’s PD 20W will charge much faster than the Miady’s standard 2.4 amp output.
Which power bank is best for charging multiple devices at once?
The VTIAEK is the winner here with 6 total output ports (2 built-in Lightning cables, 2 built-in USB-C cables, 1 USB-A, and 1 USB-C port). The Ekrist can charge 3 devices at once with its 2 USB-A ports and 1 USB-C port. The Miady also handles 3 devices with 2 USB-A ports and 1 USB-C port. If you travel with a group or have a phone, tablet, and earbuds, the VTIAEK is the most versatile.
Are any of these power banks safe for overnight charging?
All three have safety features to prevent overcharging. The Ekrist uses an AI smart chip and NTC temperature control to reduce overheating risks by up to 97%. The Miady has auto shut-off protection, and the VTIAEK has 10 built-in cryogenic IC ice cores with multiple system protections. I’ve left each one charging overnight and never had an issue, but I always recommend unplugging once fully charged.
My Final Verdict
The VTIAEK 2-Pack is my overall winner for value. You get two power banks with built-in 4 cables, PD 20W fast charging that hits 80% in 20 minutes, and a digital LED display for exact battery percentage — all at a price that undercuts the competition. The Ekrist 25800mAh is the runner-up for anyone who prioritizes raw capacity over portability, since it can charge a phone five times on a single charge.
If you’re still on the fence, ask yourself this: do you want one massive battery that lasts for days, or two slim batteries with built-in cables that you never have to remember to pack? For most people, the VTIAEK’s convenience and speed make it the smarter buy.
