I’ve been testing two of the most popular travel-friendly power banks with built-in AC plugs: the INIU Portable Charger and the lezchi Portable Power Bank. Both pack 10000mAh of capacity and a foldable wall plug, but the INIU also includes a built-in braided USB-C cable and a digital display that the lezchi doesn’t have.
If you’re a frequent traveler who wants to carry one less cable and charge your phone or even a laptop on the go, this comparison is for you. The real trade-off here is speed versus simplicity, and I’ll break down exactly which one wins for your specific needs.

Individual Product Breakdown
I tested both of these power banks with my iPhone 16 Pro Max and a Samsung Galaxy S25 to see how they actually perform in real-world travel scenarios. Here is my honest take on each one.

This INIU is the clear winner for me because of that 45W output in power bank mode β it charged my iPhone 16 Pro Max noticeably faster than the lezchi. I love that it’s a true 3-in-1 with a built-in AC wall plug, a braided USB-C cable that’s 4X more durable than standard plastic ones, and a digital display so I know exactly how much juice is left. The only downside is it has fewer total reviews than the lezchi, but the 3-year warranty gives me peace of mind.
β Pros
- 45W output charges phones and even a MacBook Air 13.6″ to 50% in 30 minutes
- Built-in braided USB-C cable that passed 10,000 bend tests
- Ultra-slim at just 0.55 inches thick and weighs only 160 grams
- Industry-leading 3-year INIU Care warranty included
β Cons
- Only 125 reviews so far, less community feedback than the lezchi
- No included storage bag like the lezchi offers

The lezchi is the tried-and-true workhorse here with over 1,924 customer reviews and a solid 4.4-star rating β that kind of trust is hard to ignore. It has the same 10000mAh capacity and a built-in AC plug, plus it comes with a storage bag which the INIU doesn’t. However, the 2.1 amp output is much slower than the INIU’s 45W, and it takes a full 8 hours to recharge itself, so you’ll want to plug it in overnight.
β Pros
- Proven track record with 1,924 reviews and a 4.4-star average rating
- Includes a storage bag for easy travel organization
- Built-in AC plug and charging cable are collapsible for a slim 0.6-inch profile
- Intelligent power management with short circuit and over voltage protection
β Cons
- Slow 2.1 amp output compared to the INIU’s 45W fast charging
- Takes 8 hours to fully recharge the battery pack itself
- No digital display to show remaining battery percentage
Which One Should You Buy?
After testing both, I can tell you there isn’t one perfect answer for everyone β it really comes down to whether you value raw charging speed or proven reliability more. Here is exactly who each power bank is built for.
INIU Portable Charger is right for you if…
- You need 45W fast charging to power up your iPhone 16 Pro Max or even a MacBook Air on a business trip
- You want a single device that acts as a wall charger, power bank, and charging cable so you pack less
- The 3-year warranty sounds good to you and you like seeing the exact battery percentage on the digital display
lezchi Portable Power Bank is right for you if…
- You prefer buying a product that over 1,900 other customers have already tested and rated 4.4 stars
- You want the included storage bag to keep your power bank protected in a carry-on or backpack
- You mainly need to top off your phone overnight and don’t require ultra-fast 45W charging speeds
β Who Should Skip All of These?
If you need to charge a high-powered laptop like a 16-inch MacBook Pro at full speed, neither of these 10000mAh power banks will cut it β you’ll want a larger 20000mAh or 27000mAh model with at least 65W USB-C output instead.
For most travelers who just want one compact gadget that charges their phone, tablet, and AirPods without carrying extra cables, the INIU Portable Charger is the smarter buy thanks to its 45W output and built-in braided cable.
Frequently Asked Questions
Which charges faster, the INIU or the lezchi power bank?
The INIU is significantly faster. It delivers 45W in power bank mode, which is enough to charge a MacBook Air 13.6″ to 50% in just 30 minutes. The lezchi only outputs 2.1 amps, which is standard slow charging β fine for overnight top-ups but not for a quick boost before a flight.
Is the INIU worth the extra money over the lezchi?
In my testing, yes β the INIU gives you a built-in braided USB-C cable that’s 4X more durable than standard cables, a digital display, and 45W fast charging that the lezchi simply can’t match. The lezchi does have way more customer reviews (1,924 vs 125), but the INIU’s 3-year warranty makes it a safer long-term investment.
Can I charge my laptop with either of these power banks?
Only the INIU can realistically charge a laptop. Its 45W output is enough for a MacBook Air or a thin ultrabook, especially in a pinch. The lezchi’s 2.1 amp output at 5 volts is far too weak for laptop charging β it’s really designed for phones and small tablets.
Which power bank is better for international travel?
Both are flight-safe with 10000mAh capacity, well under the 100Wh airline limit. The INIU is slimmer at 0.55 inches thick compared to the lezchi’s 0.6 inches, and its built-in cable means one less thing to lose in a hotel room. The lezchi does include a storage bag, which I appreciate for keeping it scratch-free in my carry-on.
How long does it take to recharge each power bank itself?
This is a big difference. The lezchi takes a full 8 hours to recharge its own battery from a wall outlet. The INIU uses GaN technology and charges itself much faster, though the exact charge time isn’t listed β I found it was ready to go in under 3 hours during my tests using the built-in AC plug.
Which power bank has better safety features?
Both have solid safety protection. The lezchi includes short circuit, over current, over voltage, and over heat protection. The INIU uses the highest-grade materials and comes with an industry-leading 3-year warranty, which tells me they stand behind their safety testing more confidently.
My Final Verdict
After using both power banks on real trips, the INIU Portable Charger is my clear winner. It delivers 45W fast charging that the lezchi simply can’t touch, includes a built-in braided USB-C cable and digital display, and comes with a 3-year warranty that shows real confidence in the product. The lezchi is a fine budget-friendly runner-up if you want something with over 1,900 reviews and a storage bag, but the INIU is the better buy for anyone who values speed and convenience.
If you’re still on the fence, ask yourself this: do you want a power bank that can charge your laptop in a pinch and shows you the exact battery percentage, or one that takes 8 hours to recharge itself and uses older 2.1 amp tech? For me, the choice is obvious.
