This power bank ranked #10 in our latest round of testing, and we almost didn’t bother reviewing it at all. INIU usually delivers decent gear, but this one’s a knockoff and a lazy one at that.

How We Test
We’re reviewers – not influencers. What does that mean? It means we test everything our way before we share the results. None of the content we produce is sponsored so you don’t have to wonder if we’re just trying to sell you something.
For battery banks in 2025, here’s what what we tested:
- Charging protocols – We did timed charge tests for every protocol that the battery bank claimed. For example, a battery bank might advertise PDO’s of 15W, 27W and 60W. We would run voltage stability tests for each rate. We do the same for PPS as well.
- Temperature – We captured the temperature of the battery bank for all the charge tests and noted any overheating, throttling or failure to maintain the chosen output.
- Capacity test – We fully charged and discharged each battery bank using a PD controller and an e-load. This method pushes the battery harder than normal use, revealing when it fails to maintain proper output instead of just dropping to a lower voltage.
- Recharge tests – We measure and timed the amount of energy required to fill the battery bank completely. We didn’t rely on the counters on the packs, instead we had hard cutoffs coded into our test programs
- Efficiency – From our charge/discharge tests, we calculated several efficiency values to see how much usable energy you get compared to how much went in.
Design
With a 10,000mAh (36Wh) capacity, this INIU pack has a USB-C port, a USB-A port, and a built-in USB-C cable that can also plug directly into the wall. Smart design? Sure. Original? Not even close. It’s clearly modeled after the Anker Nano 3-in-1, which itself evolved from the 733 and older Nano models. Even the simple LED display tries to mimic Anker’s charm, though it randomly dropped from 100% to 66% mid-charge. That does not exactly scream confidence-inspiring.
At 257g, the INIU is lightweight and compact. It has solid energy density (0.11 Wh/g and 0.16 Wh/cm³), making it fairly efficient for its size. The matte finish is clean, though it lacks the premium rubberized grip of higher-end models.
Performance
Despite the claimed 30W output, real-world tests showed a recharge input cap of just 20W, meaning it charges slower than most competitors. It took nearly 2.5 hours to fully recharge, where similar packs wrapped up in closer to 2.
That said, it wasn’t all bad. We measured 27.45Wh out of the claimed 36Wh, a decent 76.3% efficiency (ranked 3rd overall). It also supports PPS at 3A, which puts it above many budget brands. PDO accuracy and stability were average; PPS performance was impressive in this price bracket.

Thermals
Discharge temperatures hit 48.1°C though recharge temps were a cooler 32.4°C. Not catastrophic, but worth keeping an eye on if you plan on pushing it hard.
Value
Here’s the dealbreaker: it costs $33, more than the Anker Nano 3-in-1 it blatantly copies. And while it technically works, it charges slower, performs worse, and doesn’t feel anywhere near as refined.
Verdict
We’re reviewers, not influencers. And from that perspective: no thanks. If you want a smart, compact 10k power bank with built-in cable and plug, get the original. This clone doesn’t bring enough to the table.
