Capacity and Recharge Time
The INIU 45W ships with 10,000mAh of lithium-polymer cells, which is 37Wh at the standard 3.7V nominal rating — that figure matters because airlines regulate carry-on batteries by Watt-Hours, and at 37Wh the INIU is comfortably within the 100Wh personal-electronics limit imposed by FAA and most international carriers. In real terms 10,000mAh is enough for roughly 1.7 full charges of a modern flagship phone, or about one full charge of a 10-inch tablet, before the bank itself runs flat. Recharging the bank is brisk for the size: a 30W USB-C PD wall charger refills it in around 90 minutes, which is a significant improvement over the 5W-rated banks of a few years ago. The 500-cycle-to-80% rating is industry-standard for quality lithium-polymer cells, and INIU’s three-year warranty is genuinely generous for a sub-$30 charger.
Watt-hour to milliamp-hour math is worth understanding for anyone buying a power bank. The standard formula is Wh = mAh x V / 1000, where V is the cell’s nominal voltage (3.7V for typical lithium-polymer). The 100Wh airline limit translates to roughly 27,000mAh at 3.7V, so any bank up to about 25,000mAh is safe for carry-on without approval; anything over that needs airline-by-airline check-in approval. Some banks (notably power stations like the Jackery in this lineup) exceed the limit entirely and cannot fly. For the INIU at 37Wh, every commercial airline allows it in carry-on luggage as a personal-electronics battery, with no advance notification or special handling required.
Fast Charging and Power Delivery
The headline number is 45W USB-C Power Delivery on the single USB-C port, and that figure is real. For phones the practical effect is full PPS-class fast charging on iPhone 15/16 and Samsung Galaxy S24/S25, both of which accept around 25-27W from a 45W PD source. For tablets and small laptops the 45W output is more interesting: it is enough to slow-charge a 13-inch USB-C laptop while the lid is open at light load, and to genuinely fast-charge an iPad Pro. The bank uses Power Delivery 3.0 with PPS for fine-grained voltage adjustment, plus QC 3.0 fallback. Total combined output across the three connectors is capped lower than the single-port figure, which is normal — split the load and each device drops to a sensible mid-teens-watt level. For the price, the combination of a 45W USB-C port and a fixed cable is a genuinely useful, well-judged feature set.
Wireless and Magnetic Features
The INIU 45W is a strictly wired charger — there is no Qi or MagSafe pad, and no magnets on the case. That is the honest trade-off for the price: choosing the INIU keeps cost down and capacity-per-dollar high, but if a wireless pad on the back of an iPhone matters to you, see the magnetic banks elsewhere in our power bank coverage. For most buyers the integrated, detachable USB-C cable is more practical than wireless anyway — it eliminates the need to carry an extra cable, and it pulls clean off the case when you want to use the bank with a different device or with the bare USB-C/USB-A ports.
Build Quality and Portability
At 230g and 144 x 70 x 17 mm the INIU is genuinely pocket-class — not flat enough for a jeans pocket while wearing the jeans, but a comfortable jacket-pocket or bag charger. The shell is a soft-touch plastic that resists fingerprints, and the colour LED bar gives a clear four-segment charge indication rather than the older single-LED designs. INIU has built a reputation in the budget power bank space for sensible engineering, and the three-year warranty is the most concrete signal that the company stands behind the product. For the price point, build quality is honestly good — not premium-aluminium-construction good, but well above the no-name banks selling at the same money.
Best For: Phone, Tablet or Light Laptop?
The INIU 45W’s natural fit is a phone-plus-tablet buyer who occasionally needs to top up a small USB-C laptop. For a phone-only user a smaller, cheaper bank would do; for a primary laptop charger a 100W+ unit makes more sense. But for the person who carries an iPhone and an iPad Pro, or a Galaxy and a Surface Go, the INIU lands in the right place — 45W USB-C PD is enough to fast-charge both modern phones and tablets, the integrated cable saves bag space, and 10,000mAh covers a long travel day.

Verdict: Is the INIU 45W Worth Around $30?
Yes, with a clear understanding of what it is. At around $30 the INIU 45W 10,000mAh delivers a genuine 45W USB-C PD output, a built-in detachable cable, sensible 10,000mAh capacity that travels easily on planes, and a three-year warranty that is unusually generous at this price. The lack of wireless charging is the honest compromise. For the budget-conscious traveller who carries phone plus tablet and wants a single, no-fuss charger, it earns a strong recommendation.
Pros: Real 45W USB-C PD output at a sub-$30 price; integrated detachable cable eliminates the cable hunt; carry-on-legal 37Wh capacity; three-year warranty is unusually generous at this price; PPS support for genuine Samsung fast charging; full PD 3.0 implementation rather than basic 5W output.
Cons: No wireless or magnetic charging surface; combined wattage across ports drops well below the 45W single-port figure; soft-touch finish picks up scuffs over time; the four-LED indicator is less precise than the LCD on the Anker 737 or Triple 100W.
Frequently Asked Questions
Is the INIU 45W power bank allowed on planes?
Yes. At 37Wh it is well within the 100Wh personal-electronics limit set by the FAA and most international carriers — no special approval is needed, but it must travel in carry-on rather than checked luggage.
Can the INIU 45W charge a laptop?
It can charge a light USB-C laptop slowly with the lid open at low load, but it is not a primary laptop charger — for full laptop charging at speed a 100W-plus bank such as the Anker 737 or Anker 25,000mAh Triple 100W is the right choice.
What is the difference between 10,000mAh and 37Wh?
They are the same energy expressed two ways. 37Wh = 10,000mAh x 3.7V / 1000. Airlines regulate batteries by Watt-Hours, so the 37Wh figure is the one to check against carry-on rules.
Does the INIU 45W support PPS for Samsung phones?
Yes. The 45W USB-C port supports USB PD 3.0 with PPS, so it delivers genuine fast charging to PPS-compatible Samsung Galaxy phones and to other PPS devices.
