Today, we're taking a close look at a popular contender in the crowded market: the INIU 10000mAh 22.5W Portable Charger (Model BI-B61). Promising a blend of speed, portability, and smart features, could this be the best budget power bank or even the top-rated portable charger under $50 to keep your gadgets juiced up throughout 2025? Let's dive in!

1. First Look: Unboxing the INIU BI-B61

The unboxing experience for the INIU BI-B61 power bank is straightforward and eco-conscious, which is always a plus. Inside the compact packaging, you'll typically find:

• The INIU 10000mAh Power Bank (BI-B61) itself

• A USB-A to USB-C charging cable

• A soft travel pouch (a nice touch for protection, enhancing its portable charger for travel appeal!)

• A user manual and warranty card for the INIU charger

My initial impression? The power bank feels surprisingly premium for its price point. It has a pleasant heft without being overly heavy, and the matte finish is great for resisting fingerprints and minor scuffs. It immediately feels like a device built for the rigors of daily carry – a truly durable power bank for an active lifestyle.

2. Design & Portability: Pocket-Friendly Power?

INIU has done a commendable job with the design of the BI-B61. It's impressively slim (often marketed around 0.5 inches or 1.4cm thick), making it one of the more compact 10000mAh power banks available. This slim profile means it can comfortably slip into a jeans pocket, a small purse, or the side pocket of a backpack without creating an unsightly bulge, perfect for everyday carry (EDC) power bank needs.

The build quality feels solid. There are no creaks or flexing, suggesting it can withstand a few accidental drops (though we don't recommend testing that!). The edges are smoothly rounded, making it comfortable to hold, even alongside your smartphone while charging. The signature INIU paw print LED indicator is a cute and functional way to check the remaining charge on this INIU power bank with LED display.

3. Feature Breakdown: What Makes It Tick?

Let's get into the nitty-gritty of what this INIU portable charger offers.

Power Capacity: Is 10000mAh Enough for Daily Use?

With a 10000mAh capacity, the INIU BI-B61 hits a sweet spot for most users. This 10000mAh power bank USB C is generally enough to provide:

• Roughly 1.5 - 2.3 charges for an iPhone 15 Pro (a common power bank for iPhone)

• Around 1.2 - 1.8 charges for a Samsung Galaxy S24 Ultra (making it a great power bank for Android)

• Multiple charges for smaller devices like wireless earbuds or smartwatches.

This capacity makes it an excellent travel power bank, as it's substantial enough for a long day or even a short trip, and it typically falls within airline carry-on restrictions (usually 100Wh, and 10000mAh at 3.7V is 37Wh). It's a reliable backup battery for a phone.

Charging Ports: USB-C Prowess and Multi-Device Charging

The BI-B61 is well-equipped for modern charging needs, featuring multiple USB port power bank functionality:

• 1 x USB-C Port (In/Out): This is the hero port, supporting both input (for recharging the power bank itself) and output (for charging your devices) with Power Delivery (PD). This makes it a true USB-C PD power bank.

• 2 x USB-A Ports (Out): These offer broader compatibility for older devices or for charging multiple gadgets simultaneously, supporting Quick Charge (QC).

This trio of ports means you can charge up to three devices at once, though speeds will be distributed. It's a versatile phone charger bank.

Blazing Speeds: 22.5W Fast Charging Explained (PD & QC 4.0+)

One of the standout features is its 22.5W fast charging capability. The USB-C port supports USB Power Delivery (PD), and the USB-A ports are compatible with Qualcomm Quick Charge (QC 4.0+). This high-speed charging power bank translates to significantly reduced charging times for compatible devices. INIU claims it can charge an iPhone from 0 to 60% in about 30 minutes. Recharging the power bank itself is also swift – expect around 3-3.5 hours using a compatible PD wall adapter (not included). This is a game-changer if you're often short on time and need a quick charge power bank.

Bonus Feature: The Integrated Phone Stand for On-the-Go Viewing

This is a surprisingly delightful and practical addition! A small, retractable stand slides out from the side of the power bank. It’s sturdy enough to hold most smartphones in landscape or portrait mode, making it perfect for watching videos, taking video calls, or just keeping your screen visible while it charges. It’s a small detail that elevates the user experience, turning this from just a power bank into a power bank with phone stand, ideal for hands-free phone charging.

Safety & Display: Charge with Confidence with INIU SmartProtect

The clear, digital LED display is a huge improvement over vague indicator lights, showing the exact remaining battery percentage. INIU also highlights its "15-Layer SmartProtect System," a comprehensive safe charging power bank feature designed to safeguard against overcharging, over-discharging, short-circuiting, and overheating. Coupled with an industry-leading 3-year warranty INIU power bank provides considerable peace of mind.

4. Real-World Performance: The Ultimate Test for the INIU BI-B61

Specs are one thing, but how does the INIU BI-B61 power bank performance hold up in the wild? After several weeks of daily use with an iPhone 15 Pro and a pair of Sony wireless earbuds, here's the rundown:

• Charging Speed: The fast charging is legit. My iPhone consistently gained around 50-60% charge in just over 30 minutes when starting from a low battery. This confirms its fast-charging portable battery claims.

• Capacity Consistency: I reliably got just under two full charges for my iPhone 15 Pro, which aligns with its 10000mAh rating considering conversion efficiency (power bank efficiency is key).

• Phone Stand Utility: Used it daily! Perfect for my desk and coffee shop breaks. It's more useful than you'd initially think for a power bank for video watching.

• Recharge Time: Using my 20W USB-C wall adapter, the power bank was back to 100% in a little over 3 hours.

• Portability: It became an unnoticed addition to my everyday carry. Slim enough not to be a bother, powerful enough to be a lifesaver. A truly lightweight travel power bank.

This reliable, fast-charging power bank truly delivered on its promises during my testing period.

5. The Good Stuff: Why We Love It (Pros) - INIU BI-B61 Advantages

• Seriously Fast Charging: 22.5W PD and QC 4.0+ make a noticeable difference (INIU 22.5W power bank).

• Versatile Port Selection: USB-C In/Out is a must-have, and dual USB-A adds flexibility.

6. Room for Improvement: Any Downsides? (Cons) - INIU BI-B61 Disadvantages

No product is flawless. The INIU BI-B61 is close, but here are a few minor points:

• Included Cable: Comes with a USB-A to USB-C cable. For optimal fast charging of the power bank or USB-C devices, you might prefer to use your own USB-C to USB-C cable.

• Phone Holder Durability (Long-Term): While functional, the plastic phone holder might be a point of wear over extended, rough use. It held up fine in testing, though.

• Shared Output: When charging multiple devices, the total 22.5W output is shared, meaning individual charging speeds will reduce. This is standard for most power banks.

7. Is the INIU BI-B61 Your Next Power Partner? Who is this for?

This power bank is an outstanding choice for a wide range of users:

• Daily Commuters & Students: Keep your phone and accessories powered through long days (power bank for students).

• Frequent Travelers: A reliable, airline-approved power bank that won't weigh you down (best power bank for international travel).

• Budget-Conscious Tech Enthusiasts: Get premium fast-charging features without the premium price tag (affordable fast charging power bank).

• Anyone who values convenience: The phone holder is a genuinely useful perk.

• Those looking for a lightweight power bank for travel that doesn't skimp on speed.

• Outdoor enthusiasts need a power bank for hiking or camping (though consider a higher capacity for longer trips).

If you need to charge high-power devices like laptops (power bank for laptops often require higher wattage and capacity) or require ultra-high capacity (e.g., 20000mAh+ for extended off-grid use), this might be a secondary option. But for everyday smartphone and small gadget charging, it's a star. Where to buy INIU power bank? Check the link below!
