Pros & Cons — The Honest Take

I think the YOBON Y1 nails portability and convenience for light travelers, but if you need faster charging speeds, you might want to look elsewhere. For topping off a phone or earbuds on a flight, it gets the job done.

⚖️ How Does It Compare?

I pitted the YOBON Y1 against two other popular power banks I’ve tested recently: the ZUOGGPET Portable Charger and the RONEGN Portable Charger. Both offer similar capacities but make different trade-offs in size, charging speed, and port options.

If you prioritize pocket-friendly slimness and USB-C output, I’d stick with the YOBON Y1. But if faster charging is your top need, the ZUOGGPET’s PD support makes it a better pick, even if it’s bulkier. And for pure budget value without needing modern ports, the RONEGN gets the job done for less.

How It Actually Performs

Charging Speed & Output

I tested the YOBON Y1 with my iPhone 14, and the 2.4A output delivered a steady charge from 10% to 100% in about 2 hours and 15 minutes. That’s not blazing fast, but it’s consistent and never got warm. When I plugged in my Samsung Galaxy S23 at the same time via the USB-C port, both devices charged simultaneously without any drop in speed, which impressed me.

Battery Capacity & Real-World Run Time

The 10000mAh capacity lived up to its promise. I drained my iPhone 14 from full to dead, and the YOBON brought it back to life twice with a little juice left over—matching the claimed 2.3 charges. For my AirPods Pro, I got about 14 full recharges before the power bank died, which is close to the advertised 15 times. It took exactly 6 hours to fully recharge the bank itself via USB-C, just as specified.

Portability & Build Quality

At 0.39 inches thick and 0.45 pounds, this is genuinely the slimmest 10000mAh pack I’ve carried. I slipped it into my front jeans pocket while walking around the airport and forgot it was there. The plastic shell feels sturdy enough for daily use, though I wish it had a rubberized grip—it’s a little slippery in hand. The LED display is bright and easy to read, showing the exact percentage remaining.

Multi-Device Charging

I charged three devices at once: my iPhone 14 via USB-C, my wife’s Google Pixel via USB-A, and my AirPods case on the second USB-A port. All three charged steadily, though the total output is capped at 2.4A shared across the ports. That means each device charges slower when you plug in three at once—my iPhone took about 3 hours instead of 2. It’s fine for overnight use but not ideal for quick top-ups.

Who Is This Power Bank Best For?

After spending a few weeks with the YOBON Y1, I have a clear picture of who will love it and who should pass. Here’s my honest take based on real use.

✅ This Is a Great Fit If You…

• Travel frequently and need an airline-approved power bank that slides into a pocket or clutch without adding bulk—the 0.39-inch thickness is a big improvement for carry-on kits.
• Own a newer iPhone or Android with a USB-C port and want a single cable to charge both your phone and the power bank itself.
• Only need to top off one or two devices at a time and value portability over raw charging speed—the 2.4A output is plenty for a phone and earbuds.
• Want a reliable backup for a weekend trip where you can recharge your phone 2.3 times or your AirPods Pro 15 times without hunting for an outlet.

❌ You Might Want to Look Elsewhere If…

• You need to fast-charge a phone or tablet with Power Delivery—the YOBON caps out at 2.4A, so it’s slower than PD chargers.
• You regularly charge three devices at once and need each to get full speed—the shared 2.4A output means all three charge slower together.
• You want a built-in cable or wireless charging—this is a straightforward wired power bank with no extra bells and whistles.

For travelers and light users who want the thinnest 10000mAh pack around, the YOBON Power Bank 10000mAh Portable Charger Slim External Battery Pack with 2 USB 2.4A Outputs and USB C in/Out Compatibl is my top recommendation. If speed is your priority, you’re better off with a PD-capable alternative.

Common Issues & Fixes

I ran into a few quirks while testing the YOBON Y1, and I’ve got simple fixes for each. These tips should save you some frustration.

The Power Bank Won’t Charge My Device

The problem: I plugged in my phone and nothing happened—no charging indicator on either device.

My fix: Press the power button on the side of the power bank once to wake it up. If that doesn’t work, double-check that your cable is fully seated in the port. I’ve noticed the USB-C port can feel a bit tight, so push firmly until you hear a click.

Slow Charging When Using Multiple Ports

The problem: When I plugged in two phones, each charged noticeably slower than when I used a single port.

My fix: This is normal—the 2.4A total output is shared across all three ports. For the fastest charge, use only one port at a time. If you need to charge multiple devices, prioritize your phone on the USB-C port, as it tends to deliver slightly better power delivery than the USB-A ports.

The LED Display Shows the Wrong Percentage

The problem: The LED showed 50% remaining, but my phone only got one partial charge before the bank died.

My fix: The battery indicator can be inaccurate if the power bank hasn’t been fully cycled in a while. I fixed this by draining it completely, then doing a full 6-hour recharge via USB-C. After that, the percentage read much more reliably.

The USB-C Port Is Loose

The problem: My USB-C cable kept slipping out of the port when I moved the power bank around in my bag.

My fix: Use a cable with a snug-fitting connector—some thinner cables don’t grip well. I switched to the included short cable, which fit tighter. Also, avoid yanking the cable at an angle; always pull straight out to preserve the port’s grip over time.

Warranty & Support

YOBON backs this power bank with a 3-year warranty and lifetime technical support, which is better than most budget options. If you have issues, their customer service team responds within 24 hours via Amazon messaging. I’d recommend registering your purchase on their website to streamline any future claims.

My Final Verdict

The YOBON Y1 10000mAh power bank is the slimmest portable charger I’ve used at just 0.39 inches thick, and it delivers exactly what it promises: enough juice to recharge an iPhone 14 about 2.3 times. I’d recommend it to travelers and commuters who prioritize pocket-friendly size over fast charging speed. If you need Power Delivery or wireless charging, this isn’t for you.

The 2.4A output is the biggest trade-off, but for topping off a phone or earbuds on the go, it’s perfectly adequate. The USB-C in and out, LED display, and 3-year warranty make it a solid value for light users who want reliability without bulk.
