Iniu P50-E1 power bank review
I rely on a power bank daily, and while there are plenty of compact models available, very few can keep up with the high-speed charging modern phones and portable gaming devices demand.
And that’s where the Iniu P50-E1 comes in. At 83 x 52 x 26mm (3.27 × 2.05 × 1.02 in), it’s very compact, and the 160-gram (0.353 lb) weight won’t bog you down. It has a 10,000mAh capacity (36Wh) – enough for one or two phone charges (depending on the phone), or it can give a 50Wh Steam Deck an extra 55% or so charge.
The P50 stands out from other compact power banks thanks to the 45W output that supports PPS (Programmable Power Supply, the standard used by many phones for rapid charging) from 5V to 11V and up to 4.8A. It’s aimed at those who want super-fast phone charging, and it can hit the speedy 45W charge rates that models like the Samsung Galaxy S25 Ultra assist. It may possibly additionally quick-charge handheld gaming machines, although not on the full 65W some can deal with.
That said, because the P50 has a maximum output of 15V, some devices that need higher voltages won’t charge at full speed. For example, the P50 only reaches around 27W on the Pixel 10 Pro XL, versus the attainable 39W on a charger that helps increased PPS voltages.
However maybe most significantly, does the P50 really do what it says on the field? Many energy banks make daring claims, however in real-world testing they do not dwell as much as the hype. I do complete testing to confirm cost voltages, affirm protocol assist and log capability checks.
For prime-speed cellphone charging, the P50 outputs 32Wh of the 36Wh accessible. This implies 13.5% is misplaced throughout conversion, which is a better-than-average consequence. I’ll notice, nevertheless, that whereas it is going to fortunately run full pelt for greater than sufficient time to max out a cellphone’s cost fee, on a laptop computer, it slows from 45W right down to 30W after 10 minutes to assist keep away from overheating the ability financial institution. Charging on the max output till empty provides 29Wh, which can be a better-than-average consequence.
A detailed comparability is the superb 10,000mAh 4Smarts power bank. The latter measures 77 x 56 x 26 mm (3.03 × 2.20 × 1.02 in), weighs 200g (0.441 lb), and in addition has a 45W output. It produces 27Wh at max wattage and 30Wh at 20W – not fairly pretty much as good because the P50. In comparison with the Iniu, the 4Smarts additionally will get hotter below load, lacks a USB-A port, and finally prices extra, making the P50 a transparent winner on worth and options.
The P50 comes with a brief cable built-in right into a lanyard. It’s really fairly a neat answer – strong but simple to take away. I spent appreciable time swirling the P50 by the lanyard on a finger, and it did not go flying off, so I fee it as fidget-worthy.
The unit additionally has a primary digital capability show, which is pretty correct and makes it simple to see how a lot energy stays at a look. It additionally has slightly lightning bolt to point out when the ability financial institution is quick charging. You don’t get some other indicators, although, like cost present or energy.
The soft-touch plastic feels good within the hand, however it’s simple to scratch – particularly the shiny part over the display screen. As compared, I have an Iniu B6 that has been rattling round in my bag for over 2 years now that makes use of the identical building. It has loads of little marks, however it’s solely beauty and the development may be very robust. So I’m assured the P50 will even maintain up long run.
General, the Iniu P50-E1 is a really compact, light-weight energy financial institution that gives very quick cellphone charging and may prime up many laptops in a pinch.

One thing to note: if you are using multiple ports at once, they are limited to a max of 7.5W each and 15W total. This means if you want to quickly top up a device, make sure it’s the only one plugged into the P50.
The included short USB-C lanyard cable is e-marked for 5A (USB 2.0 data speeds) so it can happily handle the P50-E1’s full 45W output. Keep in mind that if using another cable, make sure it is 5A-rated, as a typical 3A cable won’t always allow you to unlock the P50’s full potential.
When pushed hard with a sustained maximum output until empty (when charging a laptop), the P50 reached a warm but not problematic 45°C (113°F), while phone charging only saw it reach 33°C (91°F).
My advice: feel free to charge your phone with the P50 tucked in a bag, but give it some open air when charging a laptop to help with heat.

How I test power banks
I get hands-on with every power bank I test and conduct extensive evaluations in both lab and real-world scenarios. Using tools like the ChargerLab POWER-Z KM003C, I measure charge voltage, check protocol support, and log capacity tests.
Each power bank is also tested with everyday devices, including phones, tablets, and laptops, and is connected to a programmable load tester for multiple charge cycles. I carry a selection daily in both pockets and bags to assess their durability and ability to withstand everyday use.
All measurements and weights are personally verified, ensuring accuracy beyond the manufacturer’s listings. It’s worth noting that many power bank reviews don’t do this sort of testing, so they should be taken with a grain of salt.
