Detailed Reviews
1. Anker 737 Power Bank — Best Portable Charger Overall 🏆
- 24,000mAh capacity — charges iPhone 15 Pro 5+ times
- 140W max output charges MacBook Air in ~2 hours
- Smart digital display shows power, time remaining
- Two USB-C ports + one USB-A port
- PowerIQ 3.0 detects and optimizes for your device
- Charges itself fully in ~2 hours via 140W input
*As an Amazon Associate, I earn from qualifying purchases
The Anker 737 is the Swiss Army knife of portable chargers. With 24,000mAh of capacity, it holds enough juice to fully charge an iPhone 5+ times, a Samsung Galaxy 4+ times, or a MacBook Air once. The 140W max output means it can fast-charge laptops — not just phones — making it the only charger many people need to carry.
The smart digital display is genuinely useful, showing remaining capacity as a percentage, estimated time to empty or full, and current power output per port. Three ports (2x USB-C, 1x USB-A) let you charge multiple devices simultaneously — phone, tablet, and earbuds at the same time.
The trade-off is size and weight. At 1.3 lbs, it’s the heaviest on this list, and it won’t fit comfortably in a pocket. It’s designed for a bag or backpack. But if you need one charger that handles everything from phones to laptops, this is it.
Who should buy this: Digital nomads, frequent travelers, and anyone who needs to charge laptops on the go. The best choice if you want maximum capacity and speed in one device.
Who should skip: If you just need to top up your phone once, this is overkill. See the Anker Nano below.
2. Ugreen 145W Power Bank — Best for Laptop Charging
- 25,000mAh capacity — largest on our list
- 145W max output handles any USB-C laptop
- TFT display with real-time power monitoring
- Three ports: 2x USB-C + 1x USB-A
- Pass-through charging (charge bank + devices simultaneously)
- Airline-safe (under 100Wh threshold)
*As an Amazon Associate, I earn from qualifying purchases
The Ugreen 145W edges out the Anker 737 in raw capacity (25,000mAh vs 24,000mAh) and matches it in power delivery. It’s purpose-built for laptop users — 145W is enough to charge a MacBook Pro 16″ at full speed, something many power banks can’t do.
Pass-through charging is a standout feature — plug the power bank into a wall outlet and connect your devices to the bank, and it charges everything simultaneously while prioritizing your devices. The TFT display provides the same useful real-time data as the Anker. It stays under the 100Wh FAA limit, so it’s airline-safe for carry-on luggage.
Who should buy this: MacBook Pro and other high-power laptop users who need maximum output. Also a solid choice if you want the largest capacity that’s still airline-approved.
Who should skip: If you don’t charge laptops, the extra capacity and wattage aren’t necessary.
3. Baseus 65W Power Bank — Best for Travel
- 20,000mAh — solid mid-range capacity
- 65W USB-C PD charges MacBook Air and most laptops
- LED display shows battery percentage
- Two USB-C + one USB-A ports
- Slim profile fits easily in bags and pockets
- Exceptional price-to-performance ratio
*As an Amazon Associate, I earn from qualifying purchases
The Baseus 65W hits the travel sweet spot: enough capacity (20,000mAh) to charge a phone 4 times or a laptop once, fast enough (65W) to charge a MacBook Air at full speed, and priced at just [Check current price on Amazon] For most travelers, this is all the power bank you need.
The slim profile slides into a jacket pocket or a laptop bag pocket without adding bulk. At under a pound, you’ll barely notice it in your carry-on. The LED display shows remaining percentage, and three ports let you charge multiple devices when needed.
Who should buy this: Travelers who want the best balance of capacity, speed, size, and price. Also an excellent everyday carry option if you want laptop charging capability without the size of the Anker 737.
Who should skip: Heavy laptop users who need 100W+ charging or multiple days of capacity.
4. Anker Nano Power Bank — Best Ultra-Compact
- 5,000mAh — one full phone charge
- Built-in USB-C connector (no cable needed)
- Foldable design fits in any pocket
- 22.5W fast charging
- Weighs just 3.5 oz (lighter than most phones)
- Available in multiple colors
*As an Amazon Associate, I earn from qualifying purchases
The Anker Nano is the power bank for people who don’t want to carry a power bank. At 3.5 oz with a built-in foldable USB-C connector, you literally plug it directly into your phone — no cable required. Slip it in your pocket in the morning and forget about it until you need it.
5,000mAh provides roughly one full charge for most smartphones, which is enough to get through a long day or an emergency. The 22.5W output is fast enough to get a meaningful charge in 20-30 minutes. It won’t charge laptops or tablets, but that’s not what it’s for.
Who should buy this: Anyone who wants a dead-simple emergency backup that fits in a pocket. Perfect for daily carry, concerts, nights out, and travel days.
Who should skip: If you need to charge multiple devices or want more than one phone charge, you need a larger bank.
5. Mophie Powerstation XXL — Best Premium Build
- 20,000mAh capacity with premium fabric finish
- 45W USB-C PD for phones and small laptops
- Priority+ charging prioritizes connected devices
- LED indicator strip for battery status
- Two-year warranty
- Available in stylish fabric and metallic finishes
*As an Amazon Associate, I earn from qualifying purchases
Mophie builds power banks that feel like premium accessories rather than utilitarian bricks. The fabric finish and refined design make the Powerstation XXL something you don’t mind pulling out of your bag. It feels well-made in a way that cheaper options don’t.
At 45W USB-C PD, it charges phones fast and can handle smaller laptops like MacBook Air (though slower than the 65W+ options above). The 20,000mAh capacity is solid for 4+ phone charges. Priority+ charging ensures your connected devices get charged first when you plug the bank into the wall.
Who should buy this: Anyone who values build quality, aesthetics, and brand reliability. Mophie’s two-year warranty is best-in-class.
Who should skip: If you want the best performance per dollar, the Baseus 65W offers more power at a lower price.
6. Nitecore NB10000 — Best Ultralight Power Bank
- 10,000mAh in a carbon fiber reinforced body
- Weighs just 5.3 oz — lightest 10K bank available
- USB-C PD (18W) + USB-A QC 3.0
- Ultra-slim profile (0.55″ thin)
- Low-current mode for earbuds and watches
- Built for hikers, cyclists, and ultralight travelers
*As an Amazon Associate, I earn from qualifying purchases
When every ounce matters — backpacking, cycling, ultralight travel — the Nitecore NB10000 is the power bank to carry. At 5.3 oz with 10,000mAh, it has the best capacity-to-weight ratio of any power bank we’ve found. The carbon fiber reinforced body is impressively thin at just 0.55 inches.
Charging speed is modest at 18W — it won’t fast-charge modern phones at their maximum rate — but it’s sufficient for overnight charging in a tent or topping up during a break. The low-current mode is useful for charging earbuds, smartwatches, and other low-draw devices that some banks can’t detect.
Who should buy this: Hikers, backpackers, cyclists, and anyone who counts grams. Also great as a daily carry for people who want to forget it’s in their bag.
Who should skip: If fast charging or laptop charging matters, you need more wattage.
How to Choose a Portable Charger
Capacity (mAh)
A typical smartphone has a 4,000-5,000mAh battery. A 10,000mAh power bank gives you roughly 2 full charges (accounting for conversion loss). A 20,000mAh bank gives you 4+ charges or one laptop charge. Choose based on your usage: 5,000mAh for emergency backup, 10,000-20,000mAh for travel, 20,000+ mAh for laptops and extended trips.
Charging Speed (Watts)
Higher wattage = faster charging. 18-22W handles phone fast charging. 45-65W charges phones fast and laptops at moderate speed. 100-140W charges high-power laptops at full speed. USB-C Power Delivery (PD) is the universal fast-charging standard — prioritize power banks with USB-C PD.
Size & Weight
There’s a direct trade-off between capacity and portability. A 5,000mAh bank fits in a pocket; a 25,000mAh bank needs a bag. Consider how you’ll carry it — daily pocket carry, laptop bag, or backpack — and choose accordingly.
Airline Restrictions
The FAA limits portable batteries to 100Wh (approximately 27,000mAh at 3.7V) in carry-on luggage. Power banks are NOT allowed in checked bags. All the power banks on this list are airline-safe, but always verify the Wh rating if you fly frequently.

Frequently Asked Questions
Can I take a portable charger on a plane?
Yes, but only in carry-on luggage — portable chargers are banned from checked bags by all major airlines. The FAA allows power banks up to 100Wh (roughly 27,000mAh) without airline approval. Power banks between 100-160Wh require airline approval. All six power banks on this list are under 100Wh and airline-safe.
How many times can a 20,000mAh power bank charge my phone?
A 20,000mAh power bank can charge a typical smartphone (4,500-5,000mAh battery) approximately 3.5 to 4 times. The number is less than the raw math suggests because of energy lost to heat during voltage conversion — typically 15-20% loss. For an iPhone 15 Pro (3,274mAh), expect about 4.5-5 full charges from a 20,000mAh bank.
Can a portable charger charge a laptop?
Yes, if the power bank supports USB-C Power Delivery at 45W or higher. A 65W power bank like the Baseus can charge a MacBook Air at full speed. For MacBook Pro or larger laptops, you’ll want 100W+ (like the Anker 737 at 140W). The power bank needs at least 20,000mAh of capacity to provide a meaningful laptop charge — expect about 50-70% of a MacBook Air charge from a 20,000mAh bank.
How long do portable chargers last before replacing?
Most quality portable chargers last 3-5 years or 500+ charge cycles before noticeable capacity degradation. After 500 cycles, expect about 80% of the original capacity. To maximize lifespan: avoid leaving the power bank fully depleted for long periods, don’t expose it to extreme heat, and use the original or a quality USB-C cable for charging.
What’s the difference between mAh and Wh?
mAh (milliamp-hours) measures charge capacity at a specific voltage, while Wh (watt-hours) measures total energy and is voltage-independent. Wh is the more accurate comparison metric and is what airlines use for limits. To convert: Wh = mAh × Voltage / 1000. A 20,000mAh power bank at 3.7V = 74Wh. Most power bank specs list mAh because the numbers look bigger and more impressive to consumers.
