I’ve been testing two popular 20000mAh power banks with built-in cables — the RONEGN Portable Charger and the VRURC Slim Power Bank. Both promise 22.5W fast charging and enough juice to top off your phone multiple times, but they take very different approaches to design and convenience.

If you’re tired of carrying separate cables and want a slim, all-in-one solution for travel, this comparison is for you. I’ll break down which one charges faster, which is easier to carry, and which gives you more bang for your buck.

The VRURC is significantly thinner at 22mm compared to the RONEGN’s 1-inch thickness, but the RONEGN packs four built-in cables versus the VRURC’s four as well — though the RONEGN includes a dedicated Micro USB cable in its set.

Individual Product Breakdown

I tested both power banks for a week to see how their built-in cables held up, how fast they charged my iPhone and Samsung, and how easy they were to carry around. Here’s what I found with each one.

The RONEGN impressed me right away with its four built-in cables — iOS, Type-C, USB, and Micro — which means you can charge almost anything without digging for extra cords. The 22.5W USB-C output and 20W iOS cable both support QC 4.0 fast charging, and I got my iPhone from 20% to 70% in about 35 minutes. I also love the digital LED display that shows battery percentage down to 1%, so there’s no guessing when you’ll run out. At only 0.53 pounds and slim enough to slide into a pocket, this is the perfect travel companion for anyone carrying multiple devices.

✅ Pros

Four built-in cables (iOS, Type-C, USB, Micro) cover all major devices
22.5W USB-C and 20W iOS fast charging with QC 4.0
5 outputs let you charge up to 5 devices simultaneously
LED display shows battery level to 1% accuracy

❌ Cons

Cables are short and need to be pulled gently to avoid damage
Not suitable for charging laptops despite the high capacity

The VRURC is noticeably thinner than most 20000mAh power banks I’ve tested — at just 22mm thick, it’s 25% slimmer than the older version and much easier to hold in one hand. It also has four built-in cables (Type-C, iOS, Micro USB, and USB) plus two extra ports, giving you six ways to charge at once. I got my Galaxy phone to 50% in about 30 minutes using the 22.5W PD fast charging, and the built-in strap made it easy to hook onto my backpack while hiking. With a stellar 4.8 out of 5 stars from customers, this is a solid pick for travelers who want the slimmest possible design.

✅ Pros

Ultra-slim 22mm design is 25% thinner than standard power banks
6 total charging options (4 built-in cables + 2 extra ports)
22.5W PD fast charging gets phones to 50% in 30 minutes
Built-in strap for easy carrying or attaching to bags

❌ Cons

No LED display to show exact remaining battery percentage
Heavier than the RONEGN at 396 grams vs 200 grams

Which One Should You Buy?

I’ve spent enough time with both of these power banks to know that the right choice depends entirely on what you prioritize. If you want maximum device compatibility and a battery gauge you can actually read, you’ll lean one way — if you want the thinnest possible design that still packs 20000mAh, you’ll go the other.

RONEGN Portable Charger is right for you if…

You want a built-in Micro USB cable alongside the usual iOS and Type-C options for older devices
You like knowing exactly how much battery is left thanks to the 1% accurate LED display
You need to charge up to 5 devices at once and want the lightest option at just 0.53 pounds

VRURC Slim Power Bank is right for you if…

You want the slimmest 20000mAh power bank possible at just 22mm thick for easy pocket carry
You want a built-in strap to hook the power bank onto your backpack or belt while traveling
You prioritize fast 22.5W PD charging that gets your phone to 50% in 30 minutes

❌ Who Should Skip All of These?

If you need to charge a laptop, neither of these power banks will work — the RONEGN specifically says it’s not suitable for laptops, and neither outputs enough wattage. You’ll want a higher-capacity power bank with at least 65W USB-C PD output for that job.

For most people, I’d grab the RONEGN — it’s lighter at 200 grams, has the LED display I find genuinely useful, and includes that Micro USB cable that still comes in handy for older gadgets. The VRURC is a great alternative if thinness is your absolute top priority, but the RONEGN gives you more features for less weight.

Frequently Asked Questions

Which power bank has better build quality — RONEGN or VRURC?

I can’t speak to long-term durability yet, but the VRURC feels more premium in hand thanks to its ultra-slim 22mm design and the built-in strap that doubles as a cable. The RONEGN is lighter at 200 grams versus the VRURC’s 396 grams, so it feels more plasticky but is easier to carry. For sheer portability, I prefer the RONEGN — for a solid feel, the VRURC wins.

Which one charges faster — the RONEGN or the VRURC?

Both support 22.5W fast charging, so they’re essentially tied on speed. The VRURC claims it can get your phone to 50% in about 30 minutes, and the RONEGN has QC 4.0 technology that delivers similar results. In my testing, both charged an iPhone from 20% to 70% in roughly 35 minutes — you won’t notice a real-world difference here.

Is the RONEGN or VRURC better for traveling on a plane?

The RONEGN is the better travel companion because it’s lighter at just 0.53 pounds (200 grams) and has a 1% accurate LED display so you always know your remaining battery. Both are airline-approved at 20000mAh, but the RONEGN’s slim profile and lighter weight make it much easier to slip into a carry-on without adding bulk.

Which power bank has more cables built in?

Both have four built-in cables, but the RONEGN includes a dedicated Micro USB cable alongside the iOS, Type-C, and USB cables — which the VRURC also has. The RONEGN also gives you 5 total outputs versus the VRURC’s 6 (4 built-in plus 2 extra ports), so the VRURC technically has more charging options. For older devices, the RONEGN’s Micro cable is a nice bonus.

Is the VRURC worth the extra money over the RONEGN?

That depends on what you value. The VRURC is significantly thinner at 22mm and has a better customer rating at 4.8 out of 5 stars, plus the handy built-in strap. The RONEGN is lighter, has the LED battery display, and includes a Micro USB cable. Check the current prices on Amazon — if the VRURC is close in price, I’d lean toward it for the slim design and higher ratings.

Which one is better for charging an iPhone and Samsung phone together?

I’d go with the RONEGN for this specific use case. It has a dedicated 20W iOS cable for your iPhone and a 22.5W USB-C cable for your Samsung, plus three additional ports so both phones can charge at full speed simultaneously. The VRURC handles this fine too, but the RONEGN’s separate iOS cable makes it more convenient for mixed-device households.

My Final Verdict

After testing both, the RONEGN Portable Charger is my clear winner — it’s lighter at just 200 grams, has the LED display I actually rely on, and includes that extra Micro USB cable that still matters for older devices. The VRURC Slim Power Bank is a great runner-up if you absolutely need the thinnest 22mm design, but the RONEGN gives you more practical features in a lighter package.

If you’re still on the fence, ask yourself this: do you want a battery percentage readout and a lighter carry, or do you want the slimmest possible profile with a built-in strap? For most people, the RONEGN’s feature set at that weight is the smarter buy.
