INIU BI-B61 10000mAh Power Bank Review
The INIU BI-B61 may have a medium-sized capacity of 10000mAh, but it’s a powerful device, especially for its size and portability. That’s because it features all the mainline fast charging protocols, including QC 4.0, PD 3.0, etc. That means it can charge any compatible device in the quickest manner possible. What’s even more impressive is that it only takes two hours to fully charge the unit itself, which is quite fast when compared to similar portable chargers. Of course, that depends a lot on your adapter’s charging speed. The power bank also has some other very useful features. Keep reading to find out more!
The portable charger as a whole may have a mid-range capacity at 10000mAh, but that’s still sufficient enough to charge the iPhone 12 2.3 times, Galaxy S10 2.1 times, iPad Mini 1.5 times, or AirPods Pro 12.5 times. It’s also compatible with any USB-C device that consumes very little energy. You won’t need to activate a special charging mode to provide power to them either. All you need to do is connect the device, and it will automatically charge.
The INIU BI-B61 10000mAh power bank has three USB ports that will power up your connected devices and the power bank. This includes two USB-A ports and one 20W USB-C port. The bi-directional PD 3.0/PD 2.0 USB-C input/output port can charge any USB-C compatible device, including tablets, headphones, AirPods, etc. The USB-C port has a rating of 5V/3A, 9V/2.22A, and 12V/1.5A.
On the other hand, both the USB-A ports support all the mainstream fast-charging technologies available today, which include QC 4.0+, QC 4.0, QC 3.0, QC 2.0, etc. This means that you can use just about any USB-A compatible smartphone with the power bank, and it will charge in the fastest possible manner. The USB-A ports have a rating of 4.5V/5A, 5V/4.5A, 9V/2A, and 12V/1.5A. When you use both output ports, the power bank will deliver 22.5W of combined power.
You’ll also be able to charge up to three devices simultaneously, and the charging rate will remain unaffected.
The power bank’s charging time will vary, depending on the wall adapter. For example, it takes 3 hours to charge if you use a 20W fast-charging adapter. Meanwhile, it takes 6 hours through a 5V/2A conventional adapter. Lastly, it takes 10 hours to charge with a 5V/1A adapter. Since charging is automatic, you won’t have any issues with the process. However, a fast-charging cable and adapter are required to use the fast-charging feature.
INIU has set the standard in terms of portable and lightweight qualities for its mid-range capacity power banks, making them as small and efficient as possible. The device measures 4.15” long, 2.60” wide, and 0.94” thick, which makes it convenient to store anywhere, including your pocket, baggage, purse, or a small compartment space. The INIU BI-B61 10000mAh power bank weighs only 6.88oz, which makes it very easy to carry around.
This power bank is very safe to take on a flight with you since it only has a rating of 37Wh, far below the 100Wh limit set by the TSA.
Look and feel
Overall, the unit’s outer shell is made of a rubberized material with a black matte finish that helps to prevent scuffs or scratches from appearing on its surface. It also has a plastic LED display screen that provides an accurate reading of how much power remains. You will find the “22.5W fast charging design by INIU” text just underneath the LED screen. Additionally, all three USB ports are located on the top in a convenient setting for easy accessibility. At the same time, each port has its own label to tell them apart from each other. Meanwhile, the power button is on the right-hand side.
Plus, the device has an attractive design with rounded corners that help to maintain its sturdiness. That way, it can stand on its own while ensuring it doesn’t slip off sloth or slippery surfaces.
One of the coolest and handiest features is the pull-out phone holder, which serves as a placeholder for your smartphone while it’s charging via the portable charger. You can store your power bank in the nylon pouch that comes packaged with this product, providing protection while it’s not in use.
Durability & build quality
There aren’t any dust-proof or water-resistant ratings for this unit, so you will need to be extra cautious if you plan to use it on vacation or during a camping trip. Otherwise, wet or dusty conditions could affect the internal circuit, effectively causing damage. Other than that, it could survive a drop to the ground due to its sturdy build quality.
Although it could tend to get a bit warm while charging, the INIU BI-B61 Power Bank was built and designed with safety in mind. It provides protection against over-charging, over-discharging, over-current, overvoltage, and short-circuit. If it detects short-circuit or an overloaded output, then it will automatically turn off while charging.
Additionally, the power bank comes with a three-year warranty that covers defects or damages. You will receive a replacement or refund if something goes wrong with the portable charger. However, you will only have 30 days to get your money back after purchase.
