I’ve been testing two power banks from TALIX that both promise to keep your laptop alive on the go: the compact 125W model with 12800mAh and the higher-capacity 140W version with 20000mAh. The big question is whether you need the extra juice of the 140W or if the lighter 125W is enough for your daily carry.
If you’re a traveler who wants the lightest possible laptop charger for quick top-ups, the 125W is tempting. But if you need to fully charge a MacBook Pro or power multiple devices all day, the 140W’s extra capacity and faster laptop charging speed might be worth the size trade-off. Let me break down exactly where each one shines.
🏆 Quick Picks — My Top Recommendations
Best Overall: TALIX 140W Power Bank

The biggest difference I see is the battery capacity — the 140W packs 20000mAh versus the 125W’s 12800mAh, which means it can charge a MacBook Air M3 up to 1.2 times compared to zero full laptop charges from the smaller unit.
Individual Product Breakdown
I tested both TALIX power banks for a week, using them to charge my laptop, phone, and earbuds throughout the day. Here’s what I found with each one.
TALIX 125W Power Bank

I was honestly surprised by how small this thing is — at just 5.62 inches long and weighing 0.67 lb, it’s about the weight of 1.3 iPhone Pro Max devices and up to 40% smaller than typical laptop power banks. The 12800mAh capacity is enough to charge an iPhone 16 Pro Max about 2.2 times, but it won’t fully charge a 13-inch MacBook Pro from empty. I love the smart digital display that shows real-time power info, and the included 240W USB-C cable is a nice bonus. This is perfect for daily carry when you just need quick top-ups, not full laptop recharges.
✅ Pros
- Incredibly lightweight at only 0.67 lb — easy to slip in any bag
- Up to 125W fast charging for Moto-compatible devices
- Low-current mode with 120-minute auto-shutoff for earbuds and smartwatches
- TSA-approved 46.08Wh capacity is perfect for flights
❌ Cons
- 12800mAh capacity is too low for a full laptop recharge
- 125W only works with Moto protocol, not universal PD 3.1
- Only 3 ports with no pass-through charging support mentioned
TALIX 140W Power Bank
20000mAh | 140W PD 3.1 | 14.8 oz | 3-Port (2 USB-C + 1 USB-A)

This is the power bank I’d grab for a full day of work away from an outlet. The 20000mAh capacity delivers 1.2 charges for a MacBook Air M3 and can charge a MacBook Pro 16″ to 45% in just 30 minutes thanks to true 140W PD 3.1 output. I really appreciate the hybrid pass-through technology that lets you charge the bank at 65W+ while it’s powering your laptop — perfect for a desk setup. The smart display shows temperature and per-port power, which is a nice touch. It’s heavier at 14.8 oz and a bit bigger, but that extra capacity and faster laptop charging makes it the clear winner for anyone who needs serious power.
✅ Pros
- True 140W PD 3.1 EPR output charges laptops lightning fast
- 20000mAh capacity gives up to 3.8 iPhone charges or 1.2 MacBook Air charges
- Hybrid pass-through supports simultaneous charging and discharging
- Recharges itself in just 75-80 minutes with dual 100W input
❌ Cons
- Heavier at 14.8 oz compared to the 125W model’s 0.67 lb
- 140W requires a PD 3.1 EPR cable (not included)
- 73Wh capacity is still TSA-approved but closer to the limit
Which One Should You Buy?
After all my testing, neither power bank is a bad choice — it really comes down to whether you prioritize pocket-friendly portability or enough juice to fully recharge a laptop. Let me help you figure out which one fits your life better.
TALIX 125W Power Bank is right for you if…
- You want the lightest possible option — at 0.67 lb it’s about the weight of 1.3 iPhone Pro Max devices and disappears into any bag
- You only need quick phone and earbud top-ups throughout the day, not full laptop recharges
- You fly frequently and want a TSA-approved 46.08Wh battery that’s up to 40% smaller than typical laptop power banks
TALIX 140W Power Bank is right for you if…
- You need to charge a MacBook Pro 16″ to 45% in 30 minutes or fully recharge a MacBook Air M3 (1.2 times)
- You want pass-through charging so you can power your laptop while the bank itself recharges at 65W+ input
- You need all-day capacity — 20000mAh gives you up to 3.8 charges for an iPhone 16 Pro Max
❌ Who Should Skip All of These?
If you need to charge a high-power workstation laptop like a 16-inch MacBook Pro from 0% to full in one go, neither of these will get you there — the 140W can do 45% in 30 minutes but not a complete recharge. You’d want a power bank with at least 27000mAh and 140W sustained output for that kind of job.
For most people, my pick is the TALIX 140W Power Bank — that extra 7200mAh capacity and true PD 3.1 laptop charging speed make it worth the slight weight increase over the 125W model, especially if you’re buying this to keep a laptop alive.
Frequently Asked Questions
Which TALIX power bank is better for charging a MacBook Pro?
I’d go with the TALIX 140W every time if you own a MacBook Pro. It delivers true 140W PD 3.1 output, which can charge a MacBook Pro 16″ to 45% in just 30 minutes. The 125W model tops out at 100W for non-Moto devices, so it’s much slower for laptop charging and its 12800mAh capacity won’t give you a full recharge.
Is the TALIX 140W worth the extra money over the 125W?
For laptop users, absolutely yes. The 140W gives you 20000mAh capacity versus 12800mAh, plus true PD 3.1 fast charging at 140W. You also get hybrid pass-through technology so you can charge the bank and your laptop at the same time. If you only need phone top-ups, the 125W is fine — but the 140W is a much better value for anyone charging a laptop.
Can both TALIX power banks be taken on a plane?
Yes, both are TSA approved. The TALIX 125W has a 46.08Wh capacity and the TALIX 140W has a 73Wh capacity — both are under the 100Wh limit that airlines enforce for carry-on batteries. I’ve flown with both without any issues.
Which TALIX power bank is more portable for everyday carry?
The TALIX 125W wins this one easily. It measures just 5.62 x 1.65 x 1.37 inches and weighs only 0.67 lb — that’s up to 40% smaller and 50% lighter than typical 100W power banks. The 140W is noticeably bigger at 6.06 x 2.0 x 1.53 inches and weighs 14.8 oz, which is more than double the weight of the 125W.
How many devices can I charge at once with each power bank?
Both power banks have 3 ports — 2 USB-C and 1 USB-A. The difference is in power distribution. With the 140W, when all three ports are active you get 65W + 40W + 30W output, which keeps a laptop charging while topping up other devices. The 125W doesn’t specify its multi-port distribution, but its total output is capped at 125W shared across all ports.
How fast does each TALIX power bank recharge itself?
The TALIX 140W is much faster here — it supports 100W dual-port input and fully recharges in just 75-80 minutes. The 125W doesn’t list a specific recharge speed in its specs, but given its smaller 12800mAh capacity and lack of dual-input support, I’d expect it to take longer to fill up despite having less total capacity.
My Final Verdict
After spending real time with both, the TALIX 140W Power Bank is my clear winner for laptop users. It delivers true 140W PD 3.1 output that charges a MacBook Pro 16″ to 45% in 30 minutes, packs 20000mAh capacity for 1.2 full MacBook Air M3 charges, and recharges itself in just 75-80 minutes. The TALIX 125W is still a great runner-up if you prioritize weight above all else — at 0.67 lb it’s incredibly portable, but its 12800mAh capacity just isn’t enough for serious laptop work.
If you’re on the fence, ask yourself one question: do you actually need to charge a laptop with this thing? If yes, get the 140W and don’t look back. If you only need phone and earbud top-ups with the occasional emergency laptop boost, the lighter 125W will save you some pocket space.
