Review: INIU B63 25,000mAh 65W PD Power Bank
Having an all-around type of power bank is the best type to get. Yes, power banks with high capacities and fast charging cost more, but they also enable you to charge most of your portable devices, such as the current one you plan to charge, and also devices you will own in the future. One of the most useful charging specs is a high-wattage Power Delivery (PD) output because most portable devices, such as tablets, phones, and laptops, are compatible with PD.
This review looks at this INIU B63 25,000mAh power bank with a 65W USB-C Power Delivery output. This can be an excellent choice for all-around portable charging; let’s look closely to see why.
Power Capacity:
The 25,000mAh capacity of this INIU B63 power bank is a lot of power that can be used to charge some devices at full power multiple times, and others will charge a single time. For phones, you can expect to charge most phones to full power about three or four times. However, it depends on the phone you’re charging and the battery size of the phone.
In our capacity test video for this INIU power bank, we used a MakerHawk load test from the USB-A port on the charger and set the output to about 15W. Once the capacity of the power bank reached 0%, we got a 16,640mAh output capacity. So for a Samsung Galaxy S10e with a battery of 3,100mAh, you can expect about five full charges.
You can expect about three full charges for charging phones with larger batteries, such as the Galaxy S22 Ultra, which has a 5,000mAh battery.
Charging tablets and laptops will likely yield about a single full charge, and you may have excess capacity, but these devices have huge batteries.
Overall, the capacity of this INIU B63 power bank is still impressive even after its conversion because it still lets you charge devices to full power multiple times. Also, conversion capacity may change depending on the charging speed, as we tested with a 15W output.
Output Charging:
Charging power from this INIU power bank is impressive, with all the ports featuring fast charging. There are two USB-C Power Delivery ports and a single USB-A port.
USB-C 1 has a 65W Power Delivery output, and USB-C 2 has a 30W PD output. The USB-A port has a 22.5W output.
In our test, we charged Lenovo Flex 5 from USB-C 1, which was able to charge at about 30W, the laptop’s max charging speed; we then connected a Galaxy Note 9 to USB-C 2, which was able to fast charge while the laptop still charged at 30W.
While the Lenovo laptop and the Note 9 charged, we charged an LG G7 from the USB-A port, and the LG G7 was only able to the standard charge. So when it comes to charging three devices simultaneously, you can fast charge two devices from USB-C 1 and USB-C 2, but not the USB-A port, which is pretty good.
You have to do it alone to fast charge from the USB-A port, with no other devices charging from the USB-C ports.
As for Programmable Power Supply (PPS), this INIU power bank indeed features super-fast charging, and we tested both USB-C ports with a Samsung Galaxy S20. The Galaxy S20 was able to super fast charge at 25W, which is its max charging speed; that said, we couldn’t figure out if this power bank features 45W of PPS, which the S21 and S22 phones are compatible with.
Input Charging:
This INIU B63 power bank is recharged via USB-C 1, and the max input speed is 45W of Power Delivery. Our test used a UGREEN 45W USB-C wall charger, which could recharge the power bank at about 41W.
To confirm that the max input speed is 45W, we also used a 100W UGREEN charger and got the same 41W. So make sure you use a 45W wall charger to recharge this power bank, and you should get the fastest 2-hour full recharge time.
Size and Weight:
This is a bit of a chunky power bank, but not exactly large. It has a length of 5.8 inches, a width of 2.8 inches, and a thickness of 1.3 inches. The weight of this power bank is 1 pound. So can you fit this into a ? Yes, if you have s that are big enough but it bulky. Overall, you’ll still be able to take this power bank with you anywhere, and you can easily hold it in your hands or place it in a backpack or purse.
Functional Components:
Using this power bank is very simple. Charging from the ports starts automatically. A power button off to the side turns on the screen at the top; the screen shows the remaining capacity percentage and a lightning symbol when devices are charging. The screen is okay, but it could be more useful considering the space it takes up; it would be more useful if it showed wattage, voltage, or amperage.
At the back of the power bank, there is a kickstand that you can slide out and that can be used to hold up your phone.
Structure and Material:
This INIU power bank is built well; we couldn’t find any weak or cheap feeling parts. Of course, remember not to drop the power bank or expose it to water, as that will damage it.
Tech:
When charging or recharging this INIU power bank, it gets a little bit warm, which is normal. Besides that, this charger still has all the other protections you can expect.
Reliability
If you need a power bank that can charge phones, laptops, and tablets, this INIU B63 power bank is a great choice. It has a high capacity to charge certain devices multiple times, and the fast charging from the ports means you can charge laptops and phones. This is not strictly an Android phone; it’s a universal power bank, as you can use a USB-C to Lightning cable to charge iPhones.
A USB-C to USB-C cable, USB-C to USB-A cable, and a carrying pouch are included. So you can get to using the power bank right out of the box.
Summary:
There’s plenty of output capacity to use the 25,000mAh because, in our test, we achieved about 16,500mAh, which can still be used to charge certain devices to full power many times. Charging power from the ports is excellent, with 65W available from USB-C 1, 30W from USB-C 2, and 22.5W from the USB-A port.
Use a 45W PD wall charger to recharge this power bank for the fastest recharge.
Charging automatically starts, but a power button can be used to turn on the screen at the top. The screen could be more valuable if it showed wattage, voltage, or amperage readings, but it only indicates the capacity.
At the back is a slide-out stand for your phone.
This power bank has a good build and gets warm during output and input charging, which is normal.
If you have devices compatible with USB-C Power Delivery charging, this INIU B63 power bank will be great.
Conclusion:
This INIU B63 power bank has everything you would want from a portable charger, with a high capacity, fast output, and input charging, and it also comes with cables that allow you to use the power bank right out of the box.

Review: Iniu BI-B63 USB-C PD (65W) 25000mAh/92.5Wh Power Bank
It’s been a while since I’ve reviewed a power bank, as I’ve been pretty happy with the units I have. However, I was approached by Iniu about reviewing their BI-B63 “ultimate” power bank under the review challenge terms and it seemed like a good step-up from what I already have.
This particular power bank sports a “flight-safe” 25000mAh/92.5Wh rating, while offering two USB-C PD ports and one USB-A port. Of note is that one of the USB-C ports is capable of 65W, making it suitable for powering many laptops that accept USB-C power input. This makes it a truly “universal” power-bank and one that is more than just to keep your phone or tablet topped up.
Unboxing
The unit was shipped directly from Iniu and seems to have taken some knocks while in transit. The unit comes in a white cardboard box with a glossy image of the power bank on the front and a very minimalist design on the rear. The product is from Shenzhen Topstar Industry Co. Ltd and is backed by a three-year warranty.
The brand claims to be “the 1st safe fast charge pro” and to “save your time, safe[sic] your charge”. I don’t usually care much for slogans, but this is the first time I’ve personally heard of the Iniu brand.
The product is packed in cardboard, which is better than being packed in plastic. The box encourages sustainability through recycling.
The cardboard tray seems to have suffered in shipment as the shifting weight of the power bank has crumpled the tray. However, it still seems everything arrived intact.
Included in the package is the power bank inside a milky plastic sleeve, a USB-A to USB-C and a USB-C to USB-C charging cable, a welcome guide and a drawstring bag. It is nice to see a full complement of accessories being provided.
The power bank itself has a nicely rounded design with a soft-touch matte-finish plastic contrasting with a mirror-gloss black plastic window. The front has a brand logo and feature text.
The rear of the unit has a full list of specifications and approvals. A ribbed indent is provided to allow the user to slide-out a phone holder. This is a small hook which protrudes out of the side of the power bank which allows a phone to rest against the power bank. This is a nice touch.
The hook protrudes out of the feature-less side of the power bank, while the other side hosts the power button which activates the display and resets the circuitry. A seam runs all the way around the power bank near the top face. Regardless, the unit is built solidly and the seam appears to resist being pried apart.
The three blue-coloured ports offered are clearly labelled. The leftmost is a 65W capable USB-C PD port, suitable for heavy loads such as a laptop. The middle port is a 30W capable USB-C PD port which is suitable for smaller laptops, tablets and phones. Finally, a USB-A port is provided to the right, supporting fast charge standards including QC3.0.
The supplied cables do not have any USB certification printing on their sheathing, although do have Iniu branding on the connectors. They support fast charging.
The power bank supports 45W input for faster charging from PD-capable sources. Outputs are capable of 65W, 30W and 22.5W individually, or up to 4530W for a total of 75W or 4522.5W for a total of 67.5W depending on the combination. As with more modern power banks, having multiple devices attached can produce limitations in support of quick charge – when all ports are active, the latter two ports are limited to 5V output.
User Experience
Overall, I found the unit to be solidly built and relatively resilient. The included drawstring bag is a nice touch, ensuring the unit doesn’t get scratched-up when placed into a bag. The matte soft-touch plastic finish is not my favourite, however, as it can attract greasy fingerprints and could become sticky in the long run.
The unit has an LED display which allows for the capacity to be shown as a percentage. This is convenient, as it allows the user to more accurately estimate the remaining charge. In my use, I found the capacity percentage to be slightly non-linear but still a relatively useful indication. Initially, however, I did experience the unit not charging past 94% or discharging and staying on at 0% for a lot longer than I expected. This suggests to me that perhaps cycling the power bank a few times is necessary for the system to “calibrate” its gauge. The display is, however, mounted at a slight angle.
Its behaviour is very similar to the LED display on the Blitzwolf BW-P12, blinking display when it falls below 10% remaining charge and blinking the units digit during charging. This suggests to me that the internal controller may be an Injoinic Technology chip or similar. Unfortunately, given how “tightly” constructed this unit is and the fact I don’t want to destroy it, there is no teardown in this review.
The display is also useful as it indicates the status of fast charging on the input and on the output. Of note is that the unit will show 100% charging status, but may still be charging as it is consuming current from the source. In this case, the fast charge icon may still be lit. I suspect this indication is there to have users think the power bank is fully charged when it is near the end of the slowest top-off part of the charge.
I had no problems running a Dell laptop from the power bank, which is excellent. Most of my electronics also charged just fine. The provision of two USB-C ports will delight those who have already moved towards a USB-C-only life, but may be a drawback for those with more legacy equipment. It may also be a drawback when charging equipment that does not comply correctly with USB-C standards, such as some flashlights which have incorrect resistors. This can lead to those devices not charging from USB-C to USB-C connections, but charging fine on USB-A to USB-C cables.
The outputs seemed to charge even moderately-low current devices just fine. After they are fully charged, the output may be turned off and attaching another load does not always wake up the power bank, necessitating pressing the power button.
Depending on the outputs or inputs connected, the capabilities will change resulting in a brief interruption to power. This is quite normal for these types of power bank, but it does mean that this is probably not a good candidate where UPS-style operation is a requirement.
Weighing the unit shows that it weighs slightly more than the 475g claimed in the specifications, measuring 488g. This is noticeable in your bag, but it is expected for the capacity.
Performance Testing
Further information was gleaned through testing the power bank using a BK Precision Model 8600 DC Electronic Load, YZX Studio USB-C Decoy Board, qc3control-based four-wire USB-A interface, Tektronix PA1000 Power Analyser, Rohde Schwarz NGM202 Power Supply and Rohde Schwarz RTM3004 Oscilloscope. Testing did take longer than expected due to the capacity of the power bank and some very ill-timed power outages that resulted in experiments needing to be repeated.
Discharge Voltage
This test looks at the output voltage during discharge to assess the stability of the output. Tests were performed at the rated maximum load for each output.
At 5V, the output was very stable and within the expected voltage range, noting the results for USB-C outputs are inclusive of voltage loss through cables and USB decoy board.
Output at 9V is also very stable over time and within expected ranges.
A similarly positive result is seen at 12V.
Finally, at 15V and 20V, the output is also very stable. This means that the charging speed for connected devices should be stable regardless of the state-of-charge of the power bank, and that the power bank has excellent output voltage regulation.
Discharge Capacity Efficiency
A summary of the computed discharge capacity and conversion efficiency figures are provided in the table below. Slight variations are expected due to differences in full-charge/empty determination of the power bank, temperature changes and quiescent consumption in the decoy board for USB-C ports.
Measured capacity ranges from about 79Wh to 87Wh of effective output when tested at the highest rated current for each output. Corresponding efficiency, assuming an honest 92.5Wh cell, ranges from 85 to 94%, with higher efficiency expected at lower currents. This result seems very reasonable.
QC3.0 Output Steps
Testing of the USB-A output in QC3.0 mode in continuous mode should result in 200mV steps on each increment or decrement voltage command.
Measured voltage steps were very close to 200mV, ranging from 193 to 207mV. Minimum voltage achieved was 3.6201V and maximum voltage is 12.0398V which is a good result.
Output I-V Curve
This test focuses on the change in output voltage as a function of load.
At 5V, it seems that USB-A shows a clear negative internal resistance behaviour which attempts to compensate for cable losses somewhat. The result for USB-C port 2 which is inclusive of cable losses seems to suggests that it may also have this behaviour, but the loses of the cable are greater than the compensation resulting in a slight loss of voltage with increasing current. The USB-C port 1, however, seems to have “steps” in the I-V curve where the voltage can abruptly change under load. This is not that normal to see, but may suggest different energy-saving operating modes. Regardless, all voltages are well within specification ranges. Over-current protection is active, cutting-out the output at between 3.37A to 3.42A.
At 9V, a similar trend is seen for USB-A and USB-C port 2, while USB-C port 1 does not have any voltage steps but also seems to exhibit a steeper voltage decline suggesting that it may not have a negative output resistance behaviour. The over-current protection is active and appears to have correctly adjusted for the USB-A port’s 9V 2A rating, cutting out at 2.33A.
At 12V, the same trend appears to persist. Over-current protection on USB-A now kicks in at 1.80A for a 1.50A rating, which is excellent to see.
At 15V and 20V, output is very much as expected and OCP disconnects the output at 3.40A.
Ripple Noise – USB-C (1)
Testing of ripple and noise was completed to assess the quality of the output power. In this case, the oscilloscope is used with 20MHz bandwidth limit switched on and AC-coupling on a 10:1 probe.
With the output at 5V and unloaded, the ripple measured 13.671mV peak-to-peak and there did not seem to be any power-saving mode active. Switching frequency appears around 300kHz. Loaded up to 3A, the ripple measured 16.611mV peak-to-peak, again, an excellent result.
At 9V/3A, the ripple measured 20.041mV peak-to-peak. At 12V/3A, this was 20.874mV peak-to-peak.
At 15V/3A, the ripple measured 16.905mV peak-to-peak. At 20V/3.25A, the ripple measured 18.914mV peak-to-peak. These results are excellent and are easily well-below the levels seen in branded mains chargers.
Zooming out, there is a bit of a random “walk” to the ripple at a longer timescale, which does increase the mean peak-to-peak voltage to 27.391mV. Even if we double the ripple figures previously measured, this is still an excellent result nonetheless.
Ripple Noise – USB-C (2)
The second USB-C port shows clear power-saving mode behaviour. The sawtooth waveform has a frequency about 2kHz and measures 29.4mV peak-to-peak. Loading up the rail at 5V/3A brings the ripple to 18.375mV peak-to-peak with a relatively sinusoidal waveform of about 125kHz.
At 9V/3A, the ripple measured 20.776mV peak-to-peak. At 12V/2.5A, the ripple measured 20.139mV. It is remarkable just how stable the ripple is throughout. The resulting values are again, excellent.
Ripple Noise – USB-A (3)
The USB-A output also shows power-saving mode behaviour, with an unloaded ripple measuring 34.3mV peak-to-peak. Loaded at 5V/3A, this reduces to 16.121mV peak-to-peak with a more triangular waveform.
Interestingly, attempting to maximise the ripple by changing the load, I was able to achieve 46.55mV peak-to-peak at a load of 100mA as it seems to be on the borderline of power-saving and active mode. Even this level of ripple is quite acceptable.
At 9V/2A, the ripple measured 18.081mV peak-to-peak. At 12V/1.5A, This was similar at 17.983mV peak-to-peak. Once again, the ripple measurement shows an excellent result that implies clean power for your devices.
Charge Time Efficiency
Testing of charging time was made using a bench-top power supply for 5V/3A (for highest accuracy) and two wall-chargers measuring the AC power – BlitzWolf BW-S6 QC3.0 Charger and Zendure SuperPort 4 100W USB-C PD Charger for the faster charge modes.
The charging times measured 8 hours 16 minutes and 4 seconds with 5V/3A input, 6 hours 26 minutes and 13 seconds for an 18W Quick Charge 3.0 input and 2 hours 29 minutes and 1 second for a 45W USB-C PD input. The advantage of USB-C PD charging is clearly evident and allows for this power bank to be charged relatively quickly. Charging at 45W only results in a little warmth being developed.
There are other power banks which may allow for 65W charging, but my experience is that they likely get quite a bit hotter and this could be detrimental to cell lifetime. As a result, the 45W charging rate is perhaps a good compromise in spite of the 65W output capability.
Conclusion
Measured capacity ranges from about 79Wh to 87Wh of effective output with a corresponding efficiency ranging from 85 to 94% at full-rated current. Charging required 110.93Wh with a charge efficiency approximately 83.4%. These figures are all very reasonable.
Perhaps my only gripes are the soft-touch plastic finish which can attract greasy fingerprints and eventually get sticky. Another is the slightly-crooked capacity display which isn’t entirely accurate out-of-the-box and seems to need a few charges and discharges to read correctly. It also seems to indicate 100% even when charging has not fully completed.
In the end, it seems the Iniu BI-B63 is worthy of a recommendation based on these results, although longevity has not been tested. It is available through Amazon and Iniu Shop.
