INIU BI-B63 25000mAh Review
The INIU BI-B63 power bank has a hefty capacity of 25000mAh and it incorporates cutting-edge charging technologies, ensuring that you will not have to wait long times to charge your electronics or the power bank itself. Are you curious to know more about INIU BI-B63? So, let us begin.
The BI-B63 sports two USB-C and one USB-A output, with one USB-C port serving as both an input and an output. The dual-function USB-C port can deliver up to 65W, while the other can support up to 30W. As a result, the INIU BI-B63 is capable of charging most laptops with medium power consumption. Additionally, both of these connectors support the Power Delivery 3.0 protocol for rapid charging. To elaborate, this technology enables high-speed charging with variable voltage up to 20V via intelligent device negotiation at a maximum current of 5A at 100W. You can charge laptops like the Apple MacBook Pro 13″, Pixelbook, and the DELL XPS 9380 in 1.5 hours thanks to the PD 3.0.
On the other hand, the other USB-C port, which supports a maximum output of 30W, is capable of charging devices mentioned above in 3.2 hours, which is also rather impressive. The USB-A port is rated at 5V 3A and has a maximum output of 22.5W. Therefore, it can only be used to charge phones and tablets. It’s worth mentioning that, in contrast to the most powerful power banks, the INIU BI-B63’s USB-A output is capable of charging small gadgets with low power consumption. Thus, if you own Bluetooth earphones, a smartwatch, a band, and a GPS device, you will never require another power bank.
This power bank features Qualcomm’s Quick Charge 4 technology in addition to PD 3.0. If your phone is compatible with this technology, you can take advantage of its rapid charging. It should
be mentioned that most phones have QC features, and even if yours does not, do not hesitate to purchase a power bank with this feature, as your next phone will very certainly have it, and you will not need to replace the power bank at that time.
According to INIU, Quick Charge 4.0 allows you to charge the iPhone 12 up to three times faster than a standard 5W charger and the latest Samsung phones at full speed with Super Fast Charging. Using the USB-C Output1 and a KINPS USB-C to Lightning cable, customers found that the iPhone 8 charged from 1% to 53% (52 percent gain) in 37 minutes. These customers reported that they noticed an increase of 49% (from 5% to 54%) in 35 minutes. Meanwhile, 9% of the BI-B63 charge was consumed in both observations.
If you have a few other USB-powered gadgets; do not worry, this power bank allows you to charge three devices simultaneously. Furthermore, despite its massive capacity of 25000mAh, INIU says that it can be charged in three hours, which is very amazing when compared to the 12 hours required for standard power banks. However, customers have noticed that charging the INIU BI-B63 from 19% to 100% takes 3 hours 26 minutes when using the INIU 25W wall charger.
According to other customers’ experiences, the INIU BI-B5 20000mAh/74Wh model charged from 1% to 50% (49% gain) in 44 minutes and then from 1% to 50% (49% gain) in 45 minutes. In both cases, 10% of the power bank’s capacity has been consumed. As a result, it’s fair to conclude that the INIU BI-B63 power bank charges the iPhone over 20% faster than the BI-B5 power bank.
Notably, it has been stated that the limiting factor for iPhone charging is Apple’s lightning connector; hence, charging speed should improve when we switch to USB-C. Moreover, with a capacity of 25000mAh, you can charge an iPad mini 3.2 times, a MacBook Pro 13″ 1.3 times, an iPhone 8, 8.9 times, or a Samsung Galaxy S10 5.2 times, which is sufficient to run your electronics for a day or two without a wall outlet.
With such a large capacity, it was expected that BI-B63 would be large in size and hefty in weight. However, this power bank is unexpectedly large and weighty, measuring 5.85×2.87×1.34 inches (149x73x34mm) and weighing 16.7oz (475g). As a result, it is not something you like carrying around in your pocket all the time. Compared to a $1 bill, the power bank is a little larger, yet it is as thick as four or five phones stacked on top of each other. Therefore, we suggest it to those who value capacity, output power, port count, charging technologies, and safe charging over portability.
INIU has an integrated phone holder, which comes in handy while watching videos or Facetime on your phone. To use this function, just pull out the holder and place your phone on it. Regrettably, the holder lacks a rubber grip that would aid in firmly holding the phone in place. Additionally, INIU included a travel pouch for carrying the power bank safely in case you prefer not to carry it in your pockets. Finally, the INIU BI-B63 contains 96Wh and is TSA approved; in other words, you can carry it on airplanes without restriction because the Wh number is less than 100.
Look and feel
The BI-B63 features a soft, rubber-like shell. When you hold the power bank in your hand, you immediately notice its high-quality build. The matte texture on the rubber-like shell prevents fingerprints from sticking to it more frequently unless you have greasy hands. Additionally, it is less prone to scratching than the plastic casing, which is beneficial given the prolonged life of power banks.
Furthermore, INIU has integrated a display at the top of the BI-B63 that shows the power bank’s charge level and charging status. Unfortunately, however, the display is prone to smudges, which is to be expected. Nevertheless, the matte finish and the display offer the BI-B63 an exquisite appearance.
Durability & build quality
Due to the rubber-like shell, the BI-B63 is extremely robust and can survive minor impacts. However, you should bear in mind that if the power bank falls on the display side, it may shatter. The INIU has included a 15-layer protection system named SmartProtect to ensure the safety of the power bank and any connected devices. As a result, you won’t have to worry about overheating, overcharging, or short-circuiting.
INIU has not specified the charge cycles for the BI-B63; however, in general, Lithium-Polymer power banks can be charged and discharged around 500 times. Bear in mind that you may triple this amount by charging and discharging the power banks appropriately. If you want to learn how to extend the life of your power bank, please refer to the charging habits in What are the signs of a bad cell phone battery? article.
Last but not least, INIU ships the BI-B63 power banks with a three-year warranty and lifelong technical support; thus, if you experience a short-circuit or overheating, contact the company, and they will gladly assist you.

INIU BI-B63, with a capacity of 25000mAh, features three outputs and supports PD 3.0 and QC 4 charging technologies. However, it is far larger and heavier than we expected. As a result, we suggest it to people who aren’t concerned with size or weight and are looking for a power bank that can charge many devices concurrently and has a large capacity. In addition, this power bank has a very stylish look. It is constructed of high-quality materials on both the inside and exterior of the housing, providing you with peace of mind while you are without access to wall outlets for a day or two.
