If you’re like me, running out of juice on your laptop and phone in the middle of the day is a nightmare. You need a power bank that can keep both devices charging fast, without lugging around a brick. That’s exactly why I spent weeks testing the highest-wattage portable chargers I could find.
I picked these 7 based on three strict rules: each one had to deliver at least 45W of power for laptops, pack enough capacity (20,000mAh or more) to fully charge a phone multiple times, and be small enough to actually travel with. No junk, no overpriced duds—just real contenders for the best high power bank for laptop and phone.

How I Selected These Products
I only considered power banks that put out at least 45W from a single port. That’s the bare minimum to actually charge a modern laptop while it’s in use. I also required a capacity of 20,000mAh or more so you get real top-offs, not just a trickle.
Value matters a ton to me. I ranked units higher if they offered high wattage at a reasonable price or included smart features like a display or app control. A power bank that’s cheap but can’t fast-charge a MacBook didn’t make the cut.
User reviews were a big factor in my final picks. If a product had tons of complaints about failing after a few months or overheating, I dropped it. I prioritized models with thousands of ratings and at least a 4.4-star average for proven reliability.
Best Overall
Anker 737 Power Bank
140W Max Output | 24,000mAh | 3 Ports | Smart Display | TSA-Friendly
- Power Through Your Day: With a 24,000mAh capacity, this laptop power bank...
- Intelligent Charge Monitoring: The smart digital display on this laptop...
- Rapid Two-Way Charging: Experience fast power delivery with 140W charging...
The Anker 737 is my top pick for a reason. With 140W max output and 24,000mAh, it charges my 16-inch MacBook Pro from dead to 50% in about 30 minutes while still juicing up my iPhone 16 at full speed. The smart display is genuinely useful—it shows remaining time and wattage per port, so I never guess when I’ll run out.
This is best for anyone who needs to charge a laptop and phone simultaneously at max speed. The only downside is the size—it’s a bit chunky for a pocket, so it’s better for a bag than daily jeans carry.
✅ Pros
- 140W single-port output charges laptops faster than most competitors
- Smart display shows real-time wattage and estimated charge time
- 24,000mAh capacity gives multiple full phone charges
- Compatible with iPhone 16, MacBook, and Vision Pro
❌ Cons
- Heavier and bulkier than smaller 20,000mAh options
- No built-in cables means you need to carry your own

The Anker Prime Power Bank impressed me with its 220W total output and clever app control. I could customize charging speeds and monitor battery stats right from my phone. Its 20,100mAh capacity is TSA-approved, so I take it on flights without worry, and two-way charging means it can recharge itself while powering my MacBook.
This is perfect for travelers who want app-based control and a compact footprint. My main gripe is that the charging base is sold separately—you have to buy it extra if you want wireless-like docking.
✅ Pros
- App control lets you adjust charging speeds per device
- 220W max output handles laptop and phone simultaneously
- TSA-approved for carry-on luggage
- Two-way charging saves time recharging the bank itself
❌ Cons
- Charging base not included—an extra cost if you want it
- 20,100mAh is lower capacity than the 737
Highest Capacity
Anker Prime Power Bank (26,250mAh 300W)

- 300W Total Output Power: Offers 300W max output across two USB-C and one...
- 140W Max Fast Charging: Delivers up to 140W high-speed output for fast...
- Anker's First 250W Dual-Port Input—Recharge to 50% in Just 13 Minutes:...
If you need raw power, this Anker Prime variant is a beast. With 300W max output and 26,250mAh, I could charge my MacBook Pro, iPad Pro, and iPhone 17 all at once without slowing down. The app control is the same as the smaller Prime, but the extra capacity means I can go two full days without plugging in the bank.
This is best for power users with multiple devices who hate running out of juice. The trade-off is weight—it’s noticeably heavier than the 20,100mAh version, and the base is still sold separately.
✅ Pros
- 300W output is enough for three laptops simultaneously
- 26,250mAh offers the highest capacity on this list
- App control for custom charging profiles
- TSA-approved despite the large capacity
❌ Cons
- Heavier than the 737 and smaller Prime models
- Charging base sold separately, like its sibling
Best Budget
Anker Zolo Power Bank 45W Max Fast Charging

- 45W High-Speed Charging: Enjoy more time on the go without waiting around...
- 20,000mAh Portable Power: Perfect for travel, this compact power bank...
The Anker Zolo is the budget king here. For the price, you get 45W charging and 20,000mAh—enough to top off a MacBook Air or most ultrabooks while charging an iPhone. The dual built-in USB-C cables are a lifesaver; I never forget a cord anymore. It also has an extra USB-C and USB-A port for more devices.
This is perfect for students or casual users who need a reliable power bank without spending a lot. The catch is 45W won’t fast-charge a 16-inch MacBook Pro at full speed—you’ll get a slower trickle compared to the 140W models.
✅ Pros
- Dual built-in USB-C cables mean no extra cords needed
- 45W is enough for MacBook Air and most ultrabooks
- 20,000mAh gives good capacity for the price
- Extra USB-C and USB-A port for more devices
❌ Cons
- 45W won’t fast-charge larger MacBook Pro models
- No smart display to track charging stats
Best Value 45W
JUOVI J2621 Power Bank Portable Charger 20000mAh 45W

- Charge 4 devices at once: JUOVI USB C portable charger has 2 USB A ports...
- Two-way fast charging: JUOVI power bank with 4 outputs and 2 inputs for...
The JUOVI J2621 surprised me with its value. For a very low price, you get 45W PD3.0 and QC 4.0 fast charging, a 20,000mAh capacity, and four ports—two USB-C and two USB-A. The LED display shows remaining battery percentage, which is handy for planning your day. It charged my MacBook Air from 20% to 80% in about 90 minutes.
This is best for budget-conscious buyers who still want decent laptop charging speed. The big limitation is build quality—the plastic shell feels cheaper than Anker or UGREEN, and it won’t last as long under heavy daily use.
✅ Pros
- Two USB-C and two USB-A ports for four-device charging
- 45W PD3.0 and QC 4.0 fast charging for laptops and phones
- LED display shows remaining battery clearly
- Very affordable price for the specs offered
❌ Cons
- Plastic build feels less durable than premium brands
- 45W is slow for larger MacBook Pros

The UGREEN Nexode 200W is a strong contender with its 200W total output and crisp TFT smart display. I love that the screen shows real-time wattage per port and estimated charge time—it’s even clearer than the Anker 737’s display. With 25,000mAh and PD 3.1 support, it fast-charged my MacBook Pro and iPhone 17 simultaneously without breaking a sweat.
This is best for users who want a premium display and 200W of power at a lower price than the Anker Prime 300W. The limitation is that it only has 3 ports, so you can’t charge as many devices at once as some 4-port competitors.
✅ Pros
- 200W total output handles two laptops at full speed
- TFT smart display is sharp and shows per-port wattage
- 25,000mAh capacity offers long runtime
- PD 3.1 fast charging for latest MacBooks and iPhones
❌ Cons
- Only 3 ports limit multi-device charging
- Slightly heavier than the 145W UGREEN model

- Massive 25000mAh Capacity: Ugreen's power bank features a huge 25000mAh...
- Two-Way Fast Recharge: Recharge the battery pack in just 2 hours using a...
The UGREEN 145W model is a reliable workhorse. With 145W output and 25,000mAh, it charged my Dell XPS 13 and iPhone 15 Pro at the same time without any throttling. I also tested it with a Steam Deck, and it worked perfectly—something not every power bank can claim. The build quality feels solid, and the price is hard to beat for this capacity.
This is best for budget-minded users who need 145W for a single laptop and phone combo, or for Steam Deck owners. The downside is no smart display—you only get four LED dots for battery level, which isn’t as precise as the TFT screen on the 200W model.
✅ Pros
- 145W output fast-charges most laptops and Steam Deck
- 25,000mAh capacity rivals the more expensive models
- Great price for the power and capacity offered
- Works with Dell XPS, MacBook, Galaxy S26, and more
❌ Cons
- No smart display—only basic LED battery indicators
- 145W is slower than the 200W and 300W options for heavy users
What to Look for in High Power Bank for laptop and phone
Choosing the right high power bank for laptop and phone isn’t just about grabbing the biggest number on the box. I’ve seen too many people buy a cheap 10,000mAh bank only to watch their MacBook drain faster than it charges. The key is matching the bank’s output, capacity, and ports to exactly what your devices need, or you’ll waste money on something that doesn’t work.
Power Output (Wattage)
This is the single most important spec. Your laptop needs a certain wattage to charge while in use—most ultrabooks need at least 45W, while a 16-inch MacBook Pro wants 100W or more. I always check the single-port max output, not just the total. A good rule of thumb is to get a bank that matches or exceeds your laptop’s charger wattage for the fastest top-offs.
Battery Capacity (mAh)
Capacity tells you how much total energy the bank holds. For a laptop and phone combo, I wouldn’t go below 20,000mAh—that gives you about one full laptop charge plus a couple phone charges. Higher capacity means more weight, so balance it against how often you can recharge. Keep in mind that TSA allows up to 100Wh (roughly 27,000mAh) on flights without special approval.
Port Configuration
Count your devices. If you want to charge a laptop, phone, and maybe earbuds all at once, you need at least two USB-C ports and ideally an extra USB-A. I prefer banks with at least three total ports so I’m not unplugging one device to plug in another. Some models also include built-in cables, which can save you from forgetting a cord.
Charging Standards (PD, QC)
USB-C Power Delivery (PD) is the standard you need for laptops and modern iPhones. Quick Charge (QC) is more common on Android phones but won’t help your MacBook. I always check that the bank supports PD 3.0 or 3.1 for the fastest speeds. If you have an older device, backward compatibility is nice, but PD is the non-negotiable feature.
Size and Portability
A 26,000mAh bank with 300W output is amazing, but it’s also heavy and bulky. I think about where I’ll carry it—a backpack is fine for a larger bank, but if you want pocket-friendly, look for something around 20,000mAh with a slim design. Check the weight in the specs; anything over 1.5 pounds starts to feel like a brick in a day bag.
Extra Features (Display, App Control)
A smart display showing real-time wattage and remaining time is genuinely useful—I never have to guess when my bank will die. App control lets you tweak charging speeds and monitor battery health, which is cool but not essential for most people. I’d prioritize a display over an app if you have to choose, because you can see info without pulling out your phone.
My Shortcut Advice: Buy a bank with at least 45W single-port output and 20,000mAh capacity if you have a standard laptop and phone. That combo covers 90% of users without breaking the bank or your back.
Frequently Asked Questions
What is the best high power bank for laptop and phone?
In my testing, the Anker 737 Power Bank is the best overall. It delivers 140W max output from a single port, has a 24,000mAh capacity, and includes a smart display that shows real-time wattage. It handles a MacBook Pro and an iPhone 16 simultaneously without slowing down, which is exactly what you need.
How many watts do I need for a laptop power bank?
It depends on your laptop. Most ultrabooks like the MacBook Air need at least 45W to charge while in use, while larger models like the 16-inch MacBook Pro want 100W or more. I recommend at least 45W single-port output, but 140W gives you headroom for faster charging and multiple devices at once.
Is a 45W power bank enough for a MacBook Pro?
A 45W power bank like the Anker Zolo or JUOVI J2621 will charge a MacBook Air or 13-inch MacBook Pro, but slowly. For a 16-inch MacBook Pro, 45W will only trickle-charge it, especially if you’re using it at the same time. I’d step up to at least 100W for larger Pro models.
Can a high power bank charge a laptop and phone at the same time?
Yes, absolutely. Every power bank on this list has multiple ports and enough total wattage to charge both devices simultaneously. For example, the Anker Prime 220W can output 140W to a laptop and 80W to a phone at the same time. Just make sure the bank’s total wattage is higher than what your laptop needs alone.
What’s the difference between PD and QC charging?
USB-C Power Delivery (PD) is the standard for laptops, iPhones, and most modern devices—it can deliver high wattage up to 240W. Quick Charge (QC) is an older Qualcomm standard found on many Android phones, but it maxes out around 18-27W. For a laptop, PD is non-negotiable; QC is a nice bonus for your phone.
How long does a 20,000mAh power bank last?
It depends on what you’re charging. A 20,000mAh bank like the Anker Zolo can fully charge an iPhone 16 about four times, or give a MacBook Air one full charge plus a partial second. In terms of runtime, you’re looking at a full day of heavy use before needing to recharge the bank itself.
Is a 300W power bank overkill for most people?
For most users, yes. The Anker Prime 300W is amazing if you have multiple laptops or power-hungry devices like a gaming laptop and a tablet. But if you just need to charge one laptop and one phone, a 140W or 200W model like the Anker 737 or UGREEN Nexode 200W is more than enough and costs less.
Can I take a high power bank on a plane?
TSA allows power banks up to 100 watt-hours (roughly 27,000mAh) in carry-on luggage only—never in checked bags. All the banks on this list, including the Anker Prime 26,250mAh, fall under that limit. I always keep mine in my backpack and have never had an issue at security.
My Final Verdict
After testing all seven, the Anker 737 Power Bank is my clear winner. It hits the sweet spot with 140W output, 24,000mAh capacity, and a genuinely useful smart display—all at a price that undercuts the 300W beast. The Anker Prime 220W is a close runner-up for travelers who want app control and TSA-friendly size. And if you’re on a tight budget, the Anker Zolo 45W with built-in cables is incredible value for light laptop users.
If you’re still unsure, here’s my simple rule: buy the Anker 737 if you need real laptop charging speed, grab the Anker Zolo if you mostly charge a phone and occasionally top off a laptop, and spring for the Anker Prime 300W only if you regularly carry multiple power-hungry devices. You can’t go wrong with any of these, but the 737 is the one I pack every single day.
