Picking the right travel power bank is tough when you’re juggling a laptop, phone, and maybe even an Apple Watch. I’ve been testing the Selore&S-Global 18400mAh, the iWALK 20000mAh, and the PANDUK 20000mAh to see which one actually earns a spot in your carry-on.
This comparison is for anyone tired of carrying separate cables who wants fast 65W laptop charging on the go. The big trade-off here is between having a dedicated Apple Watch charger and getting a super compact, retractable cable design — and I’ll show you exactly who wins in each scenario.

Individual Product Breakdown
I spent time testing each of these power banks to see how they handle real-world travel scenarios. Here’s my honest take on what each one does well and where they fall short.
Selore&S-Global Fast Charging Power Bank 18400mAh 65W Portable Laptop Charger
18400mAh | 65W Output | 14.53 oz | Built-in USB-C & Lightning Cables
- 【All-in-One Power Bank】 Compact and powerful, featuring dual detachable...
- 【65W Ultra-Fast Charging】Full charges MacBook Pro 16" in 1.7hrs, iPhone...
- 【Smart LCD Display & High Capacity】Track real-time battery percentage,...
This is the most versatile travel companion of the three because it includes both a built-in USB-C cable and a built-in Lightning cable, so I never need to dig through my bag for the right cord. The LCD display shows me real-time battery percentage, voltage, and power status, which is a nice touch for peace of mind. At 14.53 ounces and measuring 5.2 x 2.2 x 2.1 inches, it’s small enough for a jacket pocket but still packs enough juice to charge my MacBook Pro 16″ in 1.7 hours. My only real complaint is the 18400mAh capacity is slightly smaller than the other two 20000mAh options here.
✅ Pros
- Built-in USB-C and Lightning cables so you don’t need extras
- 65W output charges MacBook Pro 16″ in just 1.7 hours
- Lightweight at only 14.53 oz (375 grams)
- Amazon’s Choice with a 4.4-star rating from 139 reviews
❌ Cons
- 18400mAh is less capacity than the 20000mAh competitors
- No retractable cable — you have to manually coil the built-in cords

The iWALK immediately stood out because of its built-in 2.3-foot retractable USB-C cable that automatically coils back into the unit with a gentle pull — no more tangled cords in my bag. It’s also 28% smaller than other 20000mAh power banks, measuring just 6.2 x 1.7 x 2 inches and weighing 422 grams, which makes it the most pocket-friendly option here. The 65W output is plenty fast for laptops, and it can fully recharge itself in only 1.38 hours with a 65W charger. The downside is that it only has a USB-C cable built-in, so Lightning users will still need to carry a separate cord.
✅ Pros
- Retractable 2.3ft USB-C cable keeps everything tidy
- 28% smaller than typical 20000mAh power banks
- Fast self-recharge in just 1.38 hours
- Lowest price in 30 days at time of testing
❌ Cons
- Only USB-C cable built-in — no Lightning option
- White color might show dirt and scuffs faster
PANDUK Power Bank 20000mAh 65W Laptop Portable Charger for Apple Watch
20000mAh | 65W Output | Built-in Cables | Magnetic Apple Watch Charger

- 🔌【5-in-1 with Built-in Cables】 Charge up to 5 devices all at once...
- ⌚ 【Magnetic Charger for Apple Watch】Unique designed for Apple Watch...
The PANDUK is the only power bank here that includes a magnetic wireless charger for Apple Watch, so it’s a no-brainer if you wear an iWatch Series 4-11, Ultra, or SE and want to ditch yet another cable. It has 20000mAh capacity, which is enough to charge a MacBook Pro 14″ 1.3 times or an iPhone 17 Pro Max 4 times, and it supports 65W fast charging via USB-C. I like that it can charge up to 5 devices at once with its built-in USB-C cable, USB-C port, USB-A port, and the Apple Watch charger. The 4.1-star rating from 58 reviews is lower than the others, and I noticed the listed dimensions of 0.1 x 0.1 x 0.1 inches seem like a data error, so double-check the actual size before buying.
✅ Pros
- Built-in magnetic wireless charger for Apple Watch Series 4-11, Ultra, SE
- Charge up to 5 devices simultaneously
- 20000mAh capacity gives 4x charges for iPhone 17 Pro Max
❌ Cons
- Lower 4.1-star rating from only 58 reviews
- Listed dimensions appear to be a data error (0.1 x 0.1 x 0.1 in)
Which One Should You Buy?
After testing all three, I can tell you there’s no single winner for everyone — it really comes down to what devices you carry and how much you hate tangled cables. Here’s my breakdown of who each power bank is actually built for.
Selore&S-Global Fast Charging Power Bank 18400mAh is right for you if…
- You own both an iPhone (Lightning) and a USB-C device and want built-in cables for both so you never need to carry extras.
- You need to charge a MacBook Pro 16″ quickly — it’ll do the job in just 1.7 hours at 65W.
- You like knowing exactly how much power you have left thanks to the smart LCD display showing real-time battery percentage and voltage.
iWALK Laptop Power Bank 20000mAh is right for you if…
- You hate dealing with loose cables — the built-in 2.3ft retractable USB-C cord coils back into the unit with one pull.
- You want the most compact 20000mAh option that’s 28% smaller than other banks with the same capacity.
- You need a power bank that can recharge itself fast — it goes from empty to full in only 1.38 hours with a 65W charger.
PANDUK Power Bank 20000mAh 65W is right for you if…
- You wear an Apple Watch Series 4-11, Ultra, or SE and want a magnetic wireless charger built right into the power bank.
- You regularly need to charge up to 5 devices at once including a laptop, phone, and watch.
- You want the most capacity for the money — 20000mAh gives you 4 full charges for an iPhone 17 Pro Max.
❌ Who Should Skip All of These?
If you only need to charge a phone and never carry a laptop, all three of these are overkill with their 65W output and higher price tags. You’d be better off with a smaller, cheaper 10000mAh power bank that’s lighter and easier to toss in a pocket.
For most travelers who carry a laptop, an iPhone, and want built-in cables without fuss, the Selore is my top pick because it’s the only one with both USB-C and Lightning cables included right out of the box. If you absolutely need Apple Watch charging, go with the PANDUK, and if compact size is your priority, the iWALK with its retractable cable is a clever choice.
Frequently Asked Questions
Which power bank is best for charging an iPhone 16 or iPhone 17?
If you own an iPhone with a Lightning port, the Selore is the clear winner because it has a built-in Lightning cable so you don’t need to carry anything extra. The iWALK only has a USB-C cable built-in, so you’d need a separate cord for a Lightning iPhone. The PANDUK also lacks a built-in Lightning cable, making the Selore the most convenient pick for Apple phone users.
Is the Selore worth getting over the iWALK if I only use USB-C devices?
If all your devices use USB-C, I’d actually lean toward the iWALK instead. The iWALK has a larger 20000mAh capacity compared to the Selore’s 18400mAh, plus its retractable 2.3ft USB-C cable is much neater than the Selore’s fixed cable that you have to manually coil. The iWALK also recharges itself faster at 1.38 hours versus the Selore’s 2 hours.
Can I take these power banks on a plane?
Yes, all three are perfectly fine for air travel since they’re under the 100Wh limit that most airlines enforce. The Selore is 18400mAh, while the iWALK and PANDUK are both 20000mAh — all well within the standard carry-on restrictions. Just remember to pack them in your carry-on bag, not checked luggage.
Which one charges a MacBook Pro 16 the fastest?
The Selore and iWALK both deliver 65W output and will charge a MacBook Pro 16 in about the same time — the Selore claims 1.7 hours for a full charge. The PANDUK also supports 65W charging, so performance is nearly identical across all three for laptops. The real difference comes down to convenience features, not charging speed.
Does the PANDUK actually charge an Apple Watch without extra cables?
Yes, the PANDUK is the only one of these three with a built-in magnetic wireless charger for Apple Watch. It works with Series 4-11, Ultra, and SE models, and PANDUK says it can fully charge an iWatch in 2 to 3 hours. If you wear an Apple Watch daily, this alone makes the PANDUK worth considering over the other two.
Which power bank is the most portable for everyday carry?
The iWALK is the most portable in my opinion because it’s 28% smaller than other 20000mAh power banks and has that retractable cable that keeps everything tidy. It measures 6.2 x 1.7 x 2 inches and weighs 422 grams. The Selore is lighter at 375 grams but has a slightly bulkier shape, while the PANDUK’s listed dimensions seem like a data error, so I’d be cautious about its actual size.
My Final Verdict
After testing all three, the Selore&S-Global 18400mAh is my clear overall winner because it’s the only one with both built-in USB-C and Lightning cables, making it the most versatile travel companion for mixed-device households. It weighs just 375 grams and delivers 65W fast charging for laptops, all while being an Amazon’s Choice pick with a 4.4-star rating. The iWALK is the best runner-up for anyone who prioritizes a super compact design with its retractable cable and 28% smaller footprint.
If you’re still on the fence, ask yourself this: do you carry both a Lightning iPhone and a USB-C laptop? If so, the Selore eliminates the need for any extra cables. If you only use USB-C devices and want the neatest cable management, grab the iWALK instead.
