Iniu Power Bank 10,000mAh

Iniu fits an impressive three ports and fun extras in its super-affordable power bank. However, the lack of USB Power Delivery and limited Quick Charge support means that it will take quite a while to bring your devices back to full strength. Plus, the better-equipped 20,000mAh Iniu power bank is just $5 extra.

Retail price: $19.99

$19.99 at Amazon

What we like

Cute paw print charge indicator
Slim and lightweight
Convenient carrying pouch and LED light

What we don't like

No Power Delivery support
Limited charging speeds
Only one USB-C port

Iniu isn’t the most prominent name in the charging accessories game, but it certainly hopes to be. Its fast-growing Amazon profile offers well-rated cables and power banks, but do they live up to the reviews? We’re here to find out in this Iniu power bank (10,000mAh) review.

What you need to know about the Iniu power bank

Iniu offers an impressive number of power banks up to 20,000mAh capacities, some with thin designs. We tested the base 10,000mAh option for this Iniu power bank review. It packs a pair of USB-A ports and a single USB-C option, and all three top out at 15W. As far as charging standards are concerned, the Iniu power bank features Quick Charge 2.0 and Apple 2.4A but does not support Power Delivery. Notably, Iniu claims the 20,000mAh variant supports Power Delivery 3.0 and Quick Charge 4+.

Iniu fits three ports and a unique LED indicator into one of the smallest and lightest power banks around.

Iniu’s 10,000mAh power bank weighs just 198g and measures 133 x 70 x 14.7mm. It’s made entirely of plastic, though the matte finish feels soft and is easy to hold onto. The power bank displays the remaining charge on a blue LED paw print, where each segment indicates 20%.

In the box, you’ll find the power bank itself with a basic startup manual. However, you also get a drawstring carrying pouch, a USB-A to USB-C cable, and a unique LED light. The light plugs into one of the Iniu power bank’s USB-A ports in case you want to do some late-night reading.

What’s good?

Iniu set out to deliver a small and light power bank, and overall, it delivered. It’s about the same size as a Pixel 5, even if the power bank is a little bit thicker. You should have no problems shoving the Iniu power bank in a backpack or even a pocket at this size.

It's tough to top the added goodies and 10,000mAh capacity for just $19.99.

The size is especially impressive when you consider that the power bank packs three total ports. All three deliver roughly the same speeds, so you can trust that your devices will share the power equally. I found that the Iniu power bank performed the best when charging an iPhone 12 Pro, thanks to the Apple 2.4A support. While the 15W charging won’t blow anyone away, the iPhone came the closest to maintaining the top speeds, as seen in the chart below.

This is also one of the most affordable power banks I’ve tested at just $19.99. When you consider that Iniu includes a carrying pouch and a USB-A-powered LED light, you’re getting quite a lot for your money. Both the LED light and included USB-A to USB-C cable come with small covers to keep debris out of your ports for life on the go.

What’s not so good?

Although Iniu nailed the size and the overall build, it came up short on speed. There’s no USB Power Delivery of any kind, and the fastest charging standard is Quick Charge 2.0. As a result, I struggled to achieve speeds beyond about 9W on a Samsung Galaxy S21. Even the iPhone 12 Pro topped out at 12W, too, which isn’t the top 15W speed the bank is reportedly capable of. Charging multiple devices at once dropped the Galaxy S21 to 6.6W while the iPhone 12 Pro managed 7.8W.

The Iniu struggles to keep pace with newer flagship phones, and multi-device speeds are sorely limited.

Iniu’s power bank isn’t powerful enough to recharge laptops with any efficiency, either. I was only able to use the USB-C port with a Surface Laptop 3 and speeds reached just 8W. Though if you really need a power bank for a laptop you’ll want one with more capacity. Speaking of, Iniu’s 20,000mAh power bank offers greater speeds and a much wider array of charging standards, all for $5 extra.

One problem the 10,000mAh and 20,000mAh Iniu power banks share is the port selection. In a world where USB-C is becoming the standard, relying on a power bank with two USB-A ports feels outdated. It’s nice that Iniu included a USB-A to USB-C cable so you can still charge your latest gadgets, though.

Iniu power bank review: Should I buy it?

If you need a super-cheap portable charger that can fit in a pocket without much fuss, the Iniu power bank is an OK choice. I enjoyed the extra features like the LED light and carrying pouch, but the speeds left me wanting better. Charging at up to 15W isn’t fast enough, especially without Power Delivery or Quick Charge 3 and above. While it’s tough to top the $19.99 asking price, if you spend just $5 extra you can get Iniu’s 20,000mAh power bank ($24.99) with Power Delivery and Quick Charge 4+. It won’t be as portable, but you’ll be getting a lot for not much additional cash.

The cheapest Iniu power bank is an OK portable charger, but spend a little extra for the 20,000mAh version and you get a lot more.

If you’re looking to limit size and stick with a 10,000mAh power bank, there are plenty of powerful options on the market. Anker’s PowerCore III Wireless ($49) matches the 10,000mAh capacity but adds a wireless charging pad and 18W speeds to the mix. If you want the very best, the Samsung 25W portable wireless battery ($79) packs USB PD PPS support for modern flagships and wireless Qi charging.
