Power banks are handy gadgets that help keep our phones, tablets, and other devices charged when there is no outlet nearby. They have become an important tool for travel, long days out, or emergency power backup. Having a reliable power bank can make life easier, especially if we use our devices for work or navigation.
There are many types and sizes of power banks, each with different charging speeds, capacities, and features. Some can charge laptops and larger devices, while others are small and easy to carry in a pocket. Choosing a power bank depends on our needs—things like how many devices we want to charge, how fast we want them to charge, and how much weight we are willing to carry.
When buying a power bank, it’s important to pay attention to battery capacity (measured in mAh), charging speed (watts or amps), number and type of ports, and overall size. Safety features, like protection from overcharging or overheating, should be considered too. We reviewed and tested many power banks to find the models that offer the best combination of power, convenience, and safety.
Best Power Banks 2025
We know how important it is to keep your devices charged while on the go. Our list highlights the five best power banks available in 2025 to help you stay connected wherever you are.
Anker PowerCore 10K
We recommend the Anker PowerCore 10K for anyone looking for a slim and reliable power bank they can take almost anywhere.
Pros
- Slim and lightweight for easy carrying
- Handles multiple phone charges with one fill
- Quick two-way USB-C charging
Cons
- Takes time to fully charge the power bank itself
- Can get warm with heavy use
- Only includes a single USB-C and USB-A port
Having just tossed the Anker PowerCore 10K in our bag for the week, its slim size was a relief. We barely noticed it was there until our phones needed a boost mid-day. The power bank easily provided two full charges for our iPhones before we needed to plug it back in, which was great for longer days out.
Its two-way USB-C charging made topping up both our device and the power bank simple. We liked the scratch-resistant finish because it actually stayed looking nice, even after getting knocked around in our backpacks. The compact build fit in small pockets and didn’t weigh us down at all.
The charging speed was quick for a portable charger in this size category. However, we did notice it takes a bit longer when recharging the battery itself. While the single USB-C and USB-A ports were enough for us, some may wish for more connections. Overall, the Anker PowerCore 10K stands out for travelers and anyone needing portable, dependable back-up power.
Skullcandy Fat Stash 2 Power Bank
Anyone needing a compact, fast-charging power bank that keeps up on busy days will be happy with how reliable the Skullcandy Fat Stash 2 is.
Pros
- Charges devices quickly with USB C fast charging
- Two USB A ports let us charge more than one device at once
- Handy, colorful design with easy-to-read power display
Cons
- Runs out of power a bit sooner than expected when charging larger devices
- Not the lightest or slimmest pocket option
- Would be better if it offered even more battery capacity
Using this Skullcandy power bank, we found it slipped easily into our bag or pocket. It packs enough battery to recharge our phones multiple times, and the digital display made it simple to see exactly how much power was left. Plugging in a phone and earbuds at the same time worked great—and both got their charge without slowing down.
Charging speed stood out, especially with compatible USB C devices. It got our phone back to 100% much faster than older power banks did. We also liked having a handy splitter cable included, which saved us space and hassle when dealing with different types of devices.
If we could change anything, it would be helpful if this model held even more charge for big electronics. It’s not extra slim, but the bright color and sturdy feel make up for it. Overall, Skullcandy Fat Stash 2 is a smart pick for anyone who needs a reliable power solution on the go.
Poseidon Pro Indestructible Charger
If we need a power bank that’s tough enough for travel and adventures, this one stands out for its durability and long battery life.
Pros
- Extremely rugged and waterproof design
- Holds a charge for years and lasts a long time
- Includes handy accessories like a carabiner and extra cables
Cons
- Heavier than some slim power banks
- Price might be higher than basic models
- Bulkier shape may not fit every small pocket
We found the Poseidon Pro Indestructible Charger to be genuinely reliable, especially when spending time outdoors. It’s built to handle drops, dust, and water, making it a great choice for those of us who are on the move or want peace of mind no matter the weather. It survived being splashed and tossed in a bag without a scratch.
Having a power bank that keeps a charge for years is rare, and the battery life impressed us when powering phones, cameras, and other gear. The extra accessories, like the carabiner and leather strap, were actually useful instead of just being add-ons.
While it feels solid in hand, we noticed the weight and bulk compared to more basic chargers. But if durability and long-term use are more important than a small form factor, the Poseidon Pro offers real value in everyday use and travel situations.
Nimble Champ Pro 20,000mAh Power Bank
This is a strong choice for people who want a large, eco-friendly power bank that’s ready for travel and everyday use.
Pros
- High-capacity battery delivers multiple charges for phones and even some laptops
- Eco-friendly materials and packaging lower its environmental impact
- Fast charging for two devices at the same time
Cons
- Heavier than many compact chargers
- Sometimes stops charging and needs to be reconnected
- Not everyone may receive a unit that works as expected
We were impressed by the Nimble Champ Pro’s slim yet powerful design. It handled several recharges for our phone while traveling. Having enough power to top off a laptop in a pinch was a real plus, especially on long trips. Charging two devices at once also helped us stay prepared when our tablet and phone both needed power.
One of the standout things for us is its focus on sustainability. The recycled plastic build and fully biodegradable packaging gave us extra peace of mind. We know we’re not just buying another piece of tech—this one is trying to do a little better for the planet.
A few things did come up during use. The charger is slightly heavier than others we’ve carried, so it’s not as pocket-friendly. Sometimes charging stops unexpectedly, which means we had to disconnect and reconnect. While our unit worked well, a few users have had problems right out of the box, so quality seems inconsistent.
Overall, the Nimble Champ Pro balances solid charging power and environmental responsibility. If you’re looking for a power bank for work, travel, or just everyday backup, it’s worth considering.
BioLite Charge 100 Max Portable Charger
The BioLite Charge 100 Max stands out if we want a powerful, reliable charger for multiple devices.
Pros
- Charges up to five devices at the same time
- Refills quickly in about 90 minutes
- Strong enough to power laptops and smaller gadgets
Cons
- Bulky compared to slim models
- Heavier than some similar power banks
- Price is on the higher side
Using the Charge 100 Max, we found it extremely effective when keeping both our laptop and phone at full power during long travel days. The five-device support let us share it with friends, which is helpful at busy airports or hotels. The 100W charging handled our laptop without struggle, and the wireless MagSafe pad made phone top-ups easy.
Its fast recharge feature stood out. Going from empty to full in such a short time gave us peace of mind before long days out. The design feels sturdy and the orange-and-grey finish looks modern, which makes it easy to spot in our bag.
While we do notice the weight in our backpack, the trade-off feels fair because of the charging capacity. This isn’t the lightest option, but if we need reliable, fast charging for several devices at once, the BioLite Charge 100 Max does the job very well.
Buying Guide
When choosing a power bank, we need to consider several important features. The right choice depends on our devices and how we plan to use the power bank.
Battery Capacity
Look at the mAh (milliampere-hour) rating. Higher numbers mean more energy, so we can charge our devices more times. For basic use, 5,000–10,000 mAh works. Heavier use needs 20,000 mAh or more.
Output Ports and Speed
Check the number and type of ports. USB-A and USB-C are common. Some power banks support fast charging, which can save us time.
| Feature | What to Look For |
|---|---|
| Capacity | 5,000 – 20,000+ mAh |
| Ports | USB-A, USB-C, wireless |
| Charging Speed | Standard or fast charging |
| Size & Weight | Compact or large |
Portability
If we travel a lot, a smaller power bank is easier to carry. Bigger models may offer more charges but can be bulky.
Safety and Build Quality
We should check for overcharge and short-circuit protection. Quality materials add durability.
Tips to remember:
- Match the power bank’s capacity with our needs.
- Make sure our devices are compatible with the ports.
- Look for safety certifications.
With these factors, we can find a power bank that meets our needs and fits our lifestyle.
Frequently Asked Questions
We focus on what power banks work best with certain devices, how they perform during travel, and which ones offer good durability. We also share facts about battery life, capacity, and designs suited for daily use.
What are the top-rated power banks for iPhone users in 2025?
We see strong reviews for models with MagSafe support this year. Brands like Anker and Belkin have reliable power banks designed to snap onto the latest iPhones.
Fast-charging support and built-in cables make them user-friendly. These features help us charge our devices quickly and keep our bags lighter.
Which power banks are best for international travelers this year?
For international trips, we want power banks that have universal compatibility and good safety features. Models with multiple output ports and different charging speeds suit most devices.
We notice that brands like RavPower and Zendure offer global voltage support and extra protections. These options work in many countries and pass security checks at most airports.
What is the most recommended power bank for durability and performance?
When we look at durability and performance, rugged models from brands like Anker and Aukey stand out. These power banks often have solid cases and water resistance.
We also check for lithium polymer batteries, which last longer and handle temperature changes better. Some units come with two-year warranties, showing the manufacturer’s trust in the build.
How do high-capacity power banks like 20000mAh stand in 2025 rankings?
High-capacity power banks, such as those with 20000mAh or more, are ideal for charging multiple devices or powering tablets and laptops. We find these models often include fast-charging, USB-C ports, and support for Power Delivery.
They are usually heavier and larger, but for many users, the extra power is worth the increase in weight and size.
Can you expect a power bank to reliably last over a decade with regular use?
Most power banks are made to last 2-5 years with regular use. After that, battery capacity starts to decrease.
We rarely see models that maintain good performance for ten years. Safe use, not overcharging, and storing in cool places may help, but a full decade is not realistic for most products.
Are there any compact power banks that offer high performance for daily use?
We see that many brands offer slim or pocket-sized power banks that can still fast-charge a phone at least once or twice. Anker, Xiaomi, and Zendure have popular models that are easy to carry.
Even with smaller size, these power banks often include quick charging, built-in cables, and LED displays. Their light weight and speed make them a top choice for daily use.
