INIU B6 Electric Power Bank Review
There are a lot of electricity banks on the market that look great on paper, but it’s hard to know how they can have a place in the real world. INIU is one of my favorite brands, thanks to a high-quality power bank with excellent features and a long warranty, but equally importantly, the price is very reasonable. That said, when shopping online, the price is usually high, but the electricity bank is usually sold for less.
Considering the price tag, the Little Iniu B6 offers a lot, with a 10,000mAh (37Wh) capacity and a 20W (9V, 2.22A) PD 3.0 output, which will at least fully charge most phones and have enough other devices to spare Cellphone or second charge. The B6 measures 13.6 x 7 x 1.5 cm and weighs 210 grams – The size and weight of the capacity are better than average and are perfect for sliding into a pocket, purse or bag.
The B6 has a USB-C port, two USB-A ports and an easy-to-read digital display that shows the capacity that is still usable. In the box, you get USB-A to USB-C cables and carry-on bags – the latter is a nice included, as the soft touch coating on the B6 is perfect for holding, but easy to scratch. The soft coating also holds the fingerprint and fuzz, which I do worry about might degrade and feel sticky in the future, but so far it has been well maintained.
The power library has an LED torch that can be turned on by pressing the power button twice. Of course, it’s not very bright, but I found it very useful for finding lost items in black bags. Plus, it actually lasts for a few days – I often use it as a portable night light when traveling. For example, some dim lighting is very helpful when trying to find a bathroom in a dark, strange hotel room and avoid the need to turn on the main light.
The B6 also features a pull-up phone stand that turns the power bank into a stand when charging – it is also convenient for traveling.

INIU B6: Test results
I conducted a thorough test of the electric banks to make sure they fit the manufacturer’s claims. All in all, B6 gives excellent results above average, especially considering the price.
In tests, the B6 has excellent voltage accuracy and can output 85% of its rated capacity at 20W (9V, 2.22A), while 91% rated capacity at 5V. These are very impressive results considering the affordable price. The B6 also supports PPS mode from 5V to 11V at 2A and 5V to 5.9V at 3a, allowing compatible phones to charge faster and more efficiently. Note that while the B6 is listed at 22.5W, the 5V 4.5A (or 4.5V 5A) is not supported on most phones.
I first tested this INIU B6 in May 2023 and has been using it as one of my major power banks ever since. Along the way, I did regular cycle tests, but there was no significant capacity loss, so I was very confident that the B6 could last for a long time. But, of course, it is worth mentioning that INIU offers a generous three-year warranty, so rest assured if you do have problems.

How do I test the electric bank
I can do hands-on with every power bank I can use and have extensive testing of how it performs in labs and in real world. Using devices like Chargerlab Power-Z KM003C, I check the charge voltage, protocol support and log capacity tests.
Each power library is also tested with real devices, including phones, tablets, laptops and other devices, and is connected to multiple charge cycles of the programmable load tester. I choose on my pockets and bags every day to evaluate their durability and ability to withstand the roughness of everyday use.
All measurements and weights are personally verified to ensure accuracy beyond the manufacturer’s list.
