Pocket-sized yet powerful, the Iniu P50-E1 delivers 45W charging for phones and other devices

FULL STORY ======================================================================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 thats where the Iniu P50-E1 comes in. At 83 x 52 x 26mm (3.27 2.05 1.02 in), its 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. Its 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 support. It can also quick-charge handheld gaming machines, though not at the full 65W some can handle.

That said, because the P50 has a maximum output of 15V, some devices that
need higher voltages wont charge at full speed. For example, the P50 only reaches around 27W on the Pixel 10 Pro XL , versus the possible 39W on a charger that supports higher PPS voltages.

But perhaps most importantly, does the P50 actually do what it says on the box? Many power banks make bold claims, but in real-world testing they don't live up to the hype. I do comprehensive testing to verify charge voltages, confirm protocol support and log capacity tests.

For high-speed phone charging, the P50 outputs 32Wh of the 36Wh available. This means 13.5% is lost during conversion, which is a better-than-average result. I will note, however, that while it will happily run full pelt for more than enough time to max out a phone's charge rate, on a laptop, it slows from 45W down to 30W after 10 minutes to help avoid overheating the power bank. Charging at the max output until empty gives 29Wh, which is also a better-than-average result.

A close comparison is the excellent 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 also has a 45W output. It produces 27Wh at max wattage and 30Wh at 20W not quite as good as the P50. Compared to the Iniu, the 4Smarts also gets warmer under load, lacks a USB-A port, and ultimately costs more, making the P50 a clear winner on value and features. The Iniu P50-E1 has dual USB-C input / outputs, plus a handy USB-A port (Image credit: Future / Lindsay Handmer)

The P50 comes with a short cable integrated into a lanyard. Its actually
quite a neat solution robust yet easy to remove. I spent considerable time swirling the P50 by the lanyard on a finger, and it didn't go flying off, so
I rate it as fidget-worthy.

The unit also has a basic digital capacity display, which is fairly accurate and makes it easy to see how much power remains at a glance. It also has a little lightning bolt to show when the power bank is fast charging. You dont get any other indicators, though, like charge current or power.

The soft-touch plastic feels nice in the hand, but it is easy to scratch especially the glossy section over the screen. In comparison, I have an Iniu B6 that has been rattling around in my bag for over 2 years now that uses the same construction. It has plenty of little marks, but its only cosmetic and the construction is very strong. So I am confident the P50 will also hold up long term.

Overall, the Iniu P50-E1 is a very compact, lightweight power bank that
offers very fast phone charging and can top up many laptops in a pinch. Image 1 of 5 The P50 can charge 3 devices at once, but not as fast as if only charging one.

You can buy the P50 directly from Iniu , Amazon, or various other
marketplaces like eBay, though it isn't typically found in brick-and-mortar stores.

List price is $32.99 / 32.99 / AU$56.46, but it's often sold at much less during sale events, so it's well worth waiting for a discount if you don't need it right away.

The power bank has a class-leading 3-year warranty, giving extra peace of
mind if you do happen to run into an issue.

The P50-E1 gives excellent results for such a compact power bank. Iniu has matched the cells well to the output and used an efficient voltage converter, so overall the power bank gives above-average results.

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 its 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-E1s full 45W output. Keep in mind that if using another cable, make sure it is 5A-rated, as a typical 3A cable wont always allow you to unlock the P50s full potential.

When pushed hard with a sustained maximum output until empty (when charging a laptop), the P50 reached a warm but not problematic 45C (113F), while phone charging only saw it reach 33C (91F).

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.

You need fast phone charging
The 45W output on the P50 is ideal for quick top-ups.

You want a very compact power bank
The Iniu P50 has one of the best capacity-to-weight ratios going. Don't buy
it if

Your phone or laptop requires 20V charging
The P50 caps out at 15V, which isnt enough to get full fast charging on some phones or laptops.

You need to fully charge a laptop
The 36Wh capacity here is not enough to do more than partially top up a laptop. Also consider

The Iniu P50 is a great fast-charging 10,000 mAh (36Wh) power bank, but below are a few other options if you are looking for something different. For even more recommendations, check out our guide to the best power banks . Or, if

What's your favorite power bank for everyday carry? Or is there a specific model you think I should test?

Let me know in the comments below. 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 manufacturers listings. Its worth noting that many power bank reviews dont do this sort of testing, so they should be taken with a grain of salt.
