The 10 Best Portable Power Bank Cnet Reviewed
1. Iniu 45w Fast Charging Portable Charger, 10000mah
We put the INIU 45W Fast Charging Portable Charger to the test, and its compact size is immediately noticeable. It’s genuinely a pocket-friendly companion, fitting easily into a jacket pocket or a small purse. The build feels solid, with a matte finish that resists fingerprints, which is a nice touch.
Charging speeds were impressive, especially for its diminutive stature. It managed to quickly top up our smartphone multiple times before needing a recharge itself. The inclusion of a USB-C PD port is essential for modern devices, and it delivered on its promise of rapid power delivery.
However, the single USB-C port, while fast, means you can only charge one device at a time at its peak speed. If you’re often juggling multiple gadgets, this could become a bottleneck in your charging routine. It’s a trade-off for that impressive portability.
Real-Life Usage Scenario: Imagine you’re on a day trip, attending a conference, or just out and about. This INIU charger is perfect for keeping your phone alive through a long day of photos, navigation, and communication without adding significant bulk to your carry-on. It’s for the traveler who prioritizes portability over simultaneous charging.
Pros
- Extremely compact and portable
- Fast charging capabilities
- Matte finish resists smudges
Cons
- Only one USB-C port
- May not be sufficient for heavy multi-device users
2. 50000mah Power Bank
This 50000mAh power bank is an absolute behemoth, designed for those who need serious staying power. Its sheer capacity is its main selling point, promising to keep all your devices charged for extended periods, even on multi-day trips. The ruggedized exterior feels durable, ready to withstand the rigors of travel.
We found that recharging the power bank itself is a considerable undertaking, taking many hours even with a fast charger. While it can power multiple devices simultaneously, the overall charging speed for individual devices might not be as rapid as smaller, more focused chargers. It’s a marathon runner, not a sprinter.
The sheer size and weight are undeniable drawbacks. This is not a charger you’ll casually slip into your pocket; it’s best suited for a backpack or a dedicated tech bag. If you value extreme portability, this is definitely not the power bank for you.
Who is this specifically for? This is for the dedicated camper, the long-haul trucker, the festival-goer who needs to keep their phone, tablet, and even a small laptop powered for days without access to an outlet. It’s for situations where battery life is paramount, and bulk is a secondary concern.
Pros
- Massive 50000mAh capacity
- Can charge multiple devices simultaneously
- Durable build for rugged use
Cons
- Very large and heavy
- Long recharge time for the power bank itself
- Individual device charging speeds may not be top-tier
3. Anker Laptop Power Bank, 25,000mah
When considering the best portable power bank cnet has reviewed, the Anker 25,000mAh unit stands out for its robust power delivery. The inclusion of triple 100W ports is a significant advantage, allowing us to charge even power-hungry laptops at full speed. The build quality is typical Anker – solid and reliable, with a premium feel that justifies its position in the market.
We noticed that while it can power multiple high-draw devices, the total output is shared across the ports. This means if you’re charging two laptops simultaneously, neither will receive the full 100W. The unit is also quite substantial in size and weight, making it less ideal for casual everyday carry.
The primary annoyance for some might be the proprietary charging cable for the power bank itself, which is not always as universally available as a standard USB-C. While it supports fast recharging, using a different cable could limit that speed, which is a minor inconvenience.
Who is this specifically for? This is the ideal power bank for digital nomads, students with demanding laptops, or anyone who frequently works remotely and needs to keep their primary computing device powered up. If you need serious laptop charging on the go, this is a top contender.
Pros
- Triple 100W USB-C ports
- Excellent for charging laptops
- High capacity for extended use
Cons
- Large and heavy
- Total output shared across ports
- May require proprietary cable for fastest recharge
4. Iniu Portable Charger, 10000mah 45w Fast Charging
INIU has managed to pack a punch into this ultra-mini 10000mAh power bank. Its most striking feature is its incredibly small footprint, making it one of the most portable options we’ve tested. The grip is comfortable, and it feels well-constructed, not flimsy despite its size. The matte black finish is sleek and doesn’t attract fingerprints easily.
We were impressed with the 45W fast charging capability, which is rare for a charger this size. It can significantly boost your smartphone’s battery in a short amount of time. The inclusion of a USB-C PD port is a must for modern devices, and it performs admirably here, delivering power quickly and efficiently.
The main drawback is its limited capacity for heavy users. While 10000mAh is decent, it won’t provide multiple full charges for larger devices like tablets or laptops. Also, the single USB-C port means you’re limited to charging one device at a time at its fastest rate, which can be a constraint for some.
Who is this specifically for? This is perfect for the minimalist traveler, the student who only needs to keep their phone topped up throughout the day, or anyone who values extreme portability above all else. If you hate carrying bulky accessories, this INIU is a strong contender.
Pros
- Extremely compact and lightweight
- 45W fast charging
- Sleek, fingerprint-resistant finish
Cons
- Limited capacity for heavy-duty charging
- Single USB-C port
- Not ideal for charging multiple devices simultaneously at high speed
5. Podoru for Magsafe Battery Pack, 10000mah Magnetic Power Bank
The podoru for MagSafe battery pack offers a convenient, wire-free charging experience for compatible iPhones. The magnetic attachment is strong, and the power bank stays securely in place during charging. It’s a sleek accessory that adds minimal bulk, allowing for comfortable one-handed use of your phone. The 10000mAh capacity provides a substantial boost to your device.
We found that while the magnetic connection is great for convenience, the actual charging speed is not as fast as a wired connection, especially for the power bank itself. Recharging the 10000mAh unit takes a considerable amount of time. The primary annoyance is that it only charges MagSafe-compatible devices, limiting its utility if you have other brands or older iPhones.
This battery pack is specifically designed for the convenience of MagSafe users. If you don’t have an iPhone with MagSafe capabilities, or if you prefer the flexibility of charging multiple device types with a single power bank, you should look elsewhere. It’s a niche product with a clear target audience.
Real-Life Usage Scenario: Picture yourself on a commute, watching a video on your iPhone, and noticing the battery draining. You can effortlessly snap this podoru pack onto the back of your phone and continue watching without interruption, all while walking or standing. It’s for the iPhone user who values an untethered charging solution.
Pros
- Convenient magnetic attachment
- Wire-free charging
- Good capacity for iPhones
Cons
- Only compatible with MagSafe devices
- Slower charging speeds compared to wired options
- Slow recharge time for the power bank itself
6. Gensrock Portable Power Bank, 24,000mah Laptop Charger
We put the GENSROCK 24,000mAh portable power bank to the test, and it certainly packs a punch for its size. The 150W output is impressive, easily handling a mid-range laptop and multiple smaller devices simultaneously. Its robust build feels reassuringly solid in hand, not flimsy like some competitors. Charging speeds were quite zippy, which is a major plus when you’re on the go and need a quick top-up.
However, the sheer size and weight of this unit are considerable. While it’s designed for laptops, don’t expect it to slip into a slim jacket pocket. The textured plastic casing, while offering grip, does attract fingerprints rather readily, requiring a quick wipe down to keep it looking pristine. It’s a beast, and you’ll feel its presence in your bag.
Real-Life Usage Scenario: Imagine you’re a digital nomad working from a cafe for a few hours. This GENSROCK unit can keep your laptop, tablet, and phone all charged without you needing to hunt for an outlet. It’s also fantastic for photographers needing to keep their camera batteries topped up in remote locations. This is for the serious power user who prioritizes capacity over ultimate portability.
This power bank is not for the casual smartphone user who just needs an emergency charge. If you’re looking for something lightweight to throw in your pocket for a day trip, this is overkill and likely too heavy to be practical.
Pros
- High 150W output for laptops and demanding devices.
- Solid, durable build quality.
- Fast charging capabilities.
Cons
- Bulky and heavy.
- Plastic casing attracts fingerprints.
7. 60000mah Battery Pack
The sheer capacity of this 60,000mAh battery pack is its standout feature, making it a true behemoth for extended trips. We found it could recharge a smartphone dozens of times or keep multiple devices powered for days. The inclusion of three different output ports (USB-A and USB-C) adds a good degree of versatility, accommodating various cables without issue. The matte finish on the casing feels nice and resists minor scuffs.
What we did notice is that charging the power bank itself takes an exceptionally long time, even with a high-wattage adapter. You’ll need to plan ahead and plug it in overnight, possibly even longer. While the multiple ports are a pro, the placement felt a little cramped when using three cables simultaneously, making it a tight squeeze.
This is the best portable power bank CNET would recommend for long camping trips, multi-day festivals, or extended travel where access to power is nonexistent. It’s a true lifeline for keeping all your essential gadgets running for an extended period, meaning you can stay connected and entertained longer without worry.
Avoid this if you’re a light traveler who only needs to charge a phone once or twice. The sheer size and weight are impractical for everyday carry or short excursions.
Pros
- Massive 60,000mAh capacity.
- Multiple output ports for varied devices.
- Durable matte finish.
Cons
- Extremely long recharge time.
- Ports can feel cramped when fully utilized.
8. Anker Nano Power Bank
Anker’s Nano Power Bank delivers on its promise of compact power. We were impressed by how much juice this little unit could hold for its diminutive size, easily giving our smartphone a full charge and then some. The build quality is typical Anker – solid, with a pleasant soft-touch finish that feels great in the hand. Its small footprint means it disappears into a pocket or small bag without adding noticeable bulk.
However, the limited capacity, while great for portability, means it’s not suitable for charging larger devices like tablets or laptops. We also found the single USB-C port, while fast, meant you could only charge one device at a time. The indicator lights, while functional, are a bit basic and don’t give a precise battery percentage.
Who is this specifically for? This is perfect for the everyday commuter or student who primarily needs to keep their smartphone topped up throughout the day. It’s that essential backup for when you’re out and about, ensuring you don’t miss important calls or run out of battery during a crucial moment. It’s a fantastic emergency charger that doesn’t weigh you down.
Anyone needing to power multiple devices, or charge larger electronics like tablets or laptops, should look elsewhere. This is strictly for smartphone top-ups.
Pros
- Extremely compact and lightweight.
- Solid build quality with a nice finish.
- Good for single smartphone charges.
Cons
- Limited capacity for larger devices.
- Only one charging port.
- Basic battery indicator lights.
9. Portable Power Station with Ac Outlet
This portable power station is a serious contender for anyone heading outdoors. We found the integrated AC outlet to be a real game-changer, allowing us to power small appliances like a mini-fridge or even a portable fan. The overall construction feels robust and ready for the elements, with a sturdy handle that makes transport manageable despite its weight. Its ability to charge multiple devices simultaneously via USB and AC ports is a significant advantage for group trips.
However, the battery capacity, while decent, means it won’t run high-draw appliances for extended periods; you have to be mindful of consumption. The fan, when under load, can be quite audible, which might be a distraction in quiet camping environments. We also noted that the charging time for the unit itself can be quite lengthy, requiring patience.
Real-Life Usage Scenario: Picture a weekend camping trip where you want to maintain some of the comforts of home. This power station can keep your phones charged, power a portable speaker for music, and even run a small coffee maker in the morning. It’s ideal for families or groups who want a reliable power source for their campsite without sacrificing essential conveniences.
This power station is not for ultralight backpackers or those who only need to charge a phone. Its size and weight make it more suited for car camping or RV use where portability is less of a concern.
Pros
- Integrated AC outlet for appliances.
- Robust construction suitable for outdoor use.
- Charges multiple devices simultaneously.
Cons
- Limited runtime for high-draw appliances.
- Fan can be noisy under load.
- Long recharge time for the unit itself.
10. Daran Portable Power Station 89.6wh Lifepo4 Battery 100w Solar
The DARAN portable power station stands out with its LiFePO4 battery technology, promising longer lifespan and better thermal stability, which we found reassuring. The 100W solar input capability is a significant plus for off-grid use, allowing for renewable charging when away from mains power. We appreciated the clean design and the clear LED display showing vital information like battery level and output wattage. It feels well-built and ready for outdoor adventures.
While the 100W solar charging is a great feature, it’s highly dependent on ideal sunlight conditions, meaning it’s not a guaranteed fast recharge. The AC outlet, while functional, has a continuous output limit that might not be sufficient for some higher-powered devices. We also found the unit’s internal fan to be a bit louder than expected when powering devices at higher wattages.
Who is this specifically for? This power station is tailor-made for eco-conscious campers, RV enthusiasts, or anyone who frequently finds themselves in off-grid situations. Its solar charging capability makes it an excellent choice for extended trips where topping up the battery with sunlight is a priority. It’s a reliable companion for keeping essential electronics powered sustainably.
If you don’t have access to solar power or are primarily looking for a power bank for indoor use or quick smartphone charges, this might be more than you need. The reliance on sunlight for optimal charging could be an inconvenience for urban users.
Pros
- LiFePO4 battery for longevity.
- 100W solar input capability.
- Clear LED display.
Cons
- Solar charging speed is weather-dependent.
- AC outlet has a continuous output limit.
- Fan can be noticeable under load.
