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 pocket? Yes, if you have pockets 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.


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.


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.



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.
