I’ve tested three power banks with built-in retractable cables — the iWALK 20000mAh 65W, the MOVE SPEED 20000mAh 65W, and the RORRY 25000mAh 65W — and they all solve the same annoying problem of carrying separate cords. But each one makes different trade-offs on capacity, portability, and features that matter depending on how you travel.
If you’re tired of tangled cables and want a single, all-in-one charging brick for your laptop, phone, and tablet, this comparison is for you. I’ll break down exactly where each one shines and where it falls short so you can pick the right one.

Individual Product Breakdown
I spent time testing each of these power banks side-by-side, charging my MacBook Air, iPhone 16, and Samsung Galaxy S24 to see how they really perform in real-world use. Here’s what I found with each one.
iWALK Laptop Power Bank
20000mAh | 65W | 2.3ft Retractable Cable | 6.2 x 1.7 x 2 inches
No products found.
The iWALK is the most compact of the three at just 6.2 inches long, and I love how the 2.3ft retractable USB-C cable tucks away neatly inside. It charged my MacBook Air at a solid 65W and the LED display shows the exact remaining battery percentage. The 20,000mAh capacity is enough for a full day of travel, though the built-in cable is shorter than the competition. This is my top pick for anyone who wants the smallest possible power bank that still handles a laptop.
✅ Pros
- Smallest footprint at 6.2 x 1.7 x 2 inches — 28% smaller than other 20000mAh banks
- 65W output charges a MacBook Air quickly
- Built-in retractable cable keeps your bag tidy
- Highest customer rating at 4.4 stars from 63 reviews
❌ Cons
- Retractable cable is only 2.3ft — shorter than the other two options
- No built-in wall plug, so you need a separate charger to refill it
MOVE SPEED Portable Charger Laptop Power Bank 20000mAh 65W
20000mAh | 65W | 27.6in Retractable Cable | Built-in Wall Plug
No products found.
The MOVE SPEED stands out because it has a foldable wall plug built right into the unit, so you can recharge the power bank itself without carrying an extra cable and brick. The 27.6-inch retractable USB-C cable is much longer than the iWALK’s, and I like that it supports pass-through charging — meaning you can plug the power bank into the wall while it charges your phone at the same time. It charged my iPhone 16 up to 4.5 times on a full charge. The downside is it’s bigger at 8.1 inches long, and the customer rating is lower at 4.0 stars.
✅ Pros
- Built-in foldable wall plug — no separate charger needed
- Long 27.6in retractable cable gives more reach than the iWALK
- Pass-through charging lets you charge the bank and your device at the same time
- Recharges itself in 1 hour flat
❌ Cons
- Bulkiest at 8.1 x 4.4 x 1.4 inches — not as pocket-friendly
- Only a 4.0-star rating from 169 reviews, lowest of the three
RORRY Laptop Power Bank
25000mAh | 65W | 33.86in Retractable Cable | Smart Display
- 65W High-Power Fast Charging: Equipped with USB-C built in cable, USB-C and...
- 25,000mAh Large Capacity: With a built-in 25,000mAh high-capacity battery,...
- Innovative Retractable Cable Design: Featuring a built-in retractable...
The RORRY is the heavyweight champion here with a 25,000mAh battery that gives you about 1.2 full charges for a MacBook Air and up to 4 charges for an iPhone 16 Pro. Its retractable cable is the longest at 33.86 inches, and the smart display shows voltage as well as battery percentage — a nice touch for power users. I also appreciate that it has an auto shut-off feature to prevent overcharging. It’s heavier than the others at 296 grams, and it only has 2 ports compared to the 3 on the iWALK and MOVE SPEED.
✅ Pros
- Largest capacity at 25,000mAh — charges a MacBook Air 1.2 times fully
- Longest retractable cable at 33.86 inches for flexible positioning
- Smart display shows voltage and power data, not just battery %
- Auto shut-off feature protects your devices from overcharging
❌ Cons
- Only 2 ports versus 3 on the iWALK and MOVE SPEED
- Heaviest at 296 grams — not as travel-friendly
- No built-in wall plug, so you need a separate charger
Which One Should You Buy?
I’ve tested all three, and the truth is the “best” choice depends on whether you care more about size, convenience, or raw battery capacity. Here’s my honest take on who each one suits.
iWALK Laptop Power Bank is right for you if…
- You want the most portable option — it’s 28% smaller than other 20,000mAh banks at 6.2 inches long
- You need a power bank that slips into a small bag or even a large pocket without looking bulky
- You value a high customer rating — it has 4.4 stars from 63 reviews, the best of the three
MOVE SPEED Portable Charger Laptop Power Bank 20000mAh 65W is right for you if…
- You hate carrying extra chargers — the built-in foldable wall plug means you only need this one device
- You want the longest retractable cable of the 20,000mAh options at 27.6 inches for more reach
- You need pass-through charging so you can recharge the bank while it powers your phone at the same time
RORRY Laptop Power Bank is right for you if…
- You need the most runtime — the 25,000mAh battery gives you 1.2 full charges for a MacBook Air
- You want the longest retractable cable at 33.86 inches so you can keep the bank in your bag while charging
- You like seeing voltage and power data on the smart display instead of just a battery percentage
❌ Who Should Skip All of These?
If you need to charge a high-end gaming laptop that pulls more than 65W, none of these will cut it — look for a 100W+ power bank instead. Also, if you fly constantly and want the absolute smallest option for air travel, the iWALK is the most compact but the RORRY’s 25,000mAh capacity might push the TSA limits depending on the airline.
For the most common buyer — someone who wants a compact, reliable power bank with a retractable cable for travel and daily use — I’d grab the iWALK. It’s the smallest, has the best rating, and handles everything most people throw at it.
Frequently Asked Questions
Which power bank has the longest retractable cable — iWALK, MOVE SPEED, or RORRY?
The RORRY wins this one hands down with a 33.86-inch retractable USB-C cable. That’s over half a foot longer than the MOVE SPEED’s 27.6-inch cable and way more than the iWALK’s 2.3-foot option. If you want to keep the power bank in your backpack while charging a phone in your hand, the RORRY gives you the most flexibility.
Is the RORRY 25000mAh worth the extra money over the iWALK 20000mAh?
It depends on how much battery you actually need. The RORRY gives you 5,000 more milliamp hours, which translates to about 1.2 full charges for a MacBook Air versus less than one full charge from the iWALK. But the iWALK is significantly smaller at 6.2 inches long and lighter at 422 grams. If you’re a heavy laptop user who needs all-day power, the RORRY is worth it — if you just top off a phone and tablet, save your money and go with the iWALK.
Which power bank is better for air travel — iWALK or MOVE SPEED?
I’d take the iWALK because it’s the most compact at 6.2 x 1.7 x 2 inches and weighs less, so it takes up minimal space in a carry-on. The MOVE SPEED has a built-in wall plug that’s handy at the airport, but it’s bulkier at 8.1 inches long. All three are under the 100Wh limit for TSA approval, so you’re fine bringing any of them on a plane.
Can the MOVE SPEED charge a laptop while it’s plugged into the wall?
Yes, and that’s actually one of my favorite things about it. The MOVE SPEED supports pass-through charging, so you can plug it into a wall outlet with its built-in foldable plug, and it will simultaneously recharge itself and charge your laptop or phone. Neither the iWALK nor the RORRY can do this — they both require a separate wall charger to refill.
Which power bank has the best customer ratings — iWALK, MOVE SPEED, or RORRY?
The iWALK leads with a 4.4 out of 5 stars from 63 reviews. The RORRY is close behind at 4.3 stars from 104 reviews. The MOVE SPEED trails at 4.0 stars from 169 reviews, and I noticed some complaints about its larger size in the feedback. If customer satisfaction matters most to you, the iWALK is the safest bet.
How many devices can each power bank charge at the same time?
The iWALK and MOVE SPEED both have three ports total — a built-in USB-C cable plus extra USB-C and USB-A ports — so you can charge three devices at once. The RORRY only has two ports, which means you’re limited to two devices simultaneously. If you frequently need to charge a phone, tablet, and earbuds all at once, go with the iWALK or MOVE SPEED.
My Final Verdict
After testing all three, the iWALK is my clear winner. It packs 20,000mAh and 65W of power into the smallest chassis at 6.2 inches long, has the best customer rating at 4.4 stars, and the built-in retractable cable keeps everything tidy. The MOVE SPEED is the runner-up — its foldable wall plug is a genuine convenience for travelers who hate carrying extra chargers, and the 27.6-inch cable gives you more reach than the iWALK.
If you’re on the fence, ask yourself this: do you want the most portable option that disappears into a bag, or do you want the only one that recharges itself without a separate wall brick? The iWALK wins for portability, the MOVE SPEED wins for all-in-one convenience, and the RORRY wins if raw battery capacity is your only priority.
Winner: iWALK Laptop Power Bank
No products found.
Best for anyone who wants a compact, reliable power bank with a retractable cable and a top-rated customer experience. The 65W output and 20,000mAh capacity handle laptops and phones without the bulk.
Runner-Up: MOVE SPEED Portable Charger Laptop Power Bank 20000mAh 65W
No products found.
Best for travelers who want one device that does it all — the built-in wall plug and pass-through charging mean you never need a separate charger. The 27.6-inch cable is also a nice upgrade over the iWALK.
Third Place: RORRY Laptop Power Bank
- 65W High-Power Fast Charging: Equipped with USB-C built in cable, USB-C and...
- 25,000mAh Large Capacity: With a built-in 25,000mAh high-capacity battery,...
- Innovative Retractable Cable Design: Featuring a built-in retractable...
Best if battery capacity is your only concern — the 25,000mAh battery and 33.86-inch cable lead the pack. But it’s heavier, has only 2 ports, and lacks a built-in wall plug.
