Best Portable Charger Anker: Top Picks & Reviews

1. Anker Power Bank, 20,000mah

We put this 20,000mAh Anker power bank through its paces during a recent long weekend trip, and it certainly lived up to its “travel essential” billing. The sheer capacity is impressive, easily topping up our smartphones multiple times and even giving a significant boost to a tablet. Its robust build felt reassuringly solid in hand, not flimsy or cheap like some other chargers we’ve encountered.

The dual USB-A ports offered decent charging speeds for our everyday devices, though we didn’t see the blazing-fast output some of the newer USB-C PD chargers provide. Recharging the power bank itself took a considerable amount of time, so planning ahead is definitely necessary if you plan to deplete it fully.

This power bank is ideal for the frequent traveler or anyone who needs reliable backup power for extended periods away from an outlet. It’s a workhorse that doesn’t fuss, just delivers. However, if you’re someone who prioritizes the absolute smallest and lightest portable charger, this might feel a bit bulky for your pocket.

A real-life usage scenario saw us using this to keep two phones and a portable speaker alive during a day of hiking and photography. We never once worried about running out of juice, and the power bank itself still had plenty left in the tank by the time we returned to our hotel.

2. Anker Nano 3

The Anker Nano 3 is a tiny powerhouse that truly impressed us with its portability. Its compact size makes it incredibly easy to slip into a pocket or a small clutch, and the matte finish gives it a premium feel. We found ourselves reaching for it constantly for quick top-ups of our earbuds and smartwatch.

While its small form factor is a definite advantage, the capacity is modest. It’s not designed to fully recharge a large smartphone from empty multiple times, but rather to provide that crucial emergency boost. The single USB-C port, while efficient, means you can only charge one device at a time.

This charger is perfect for those who value extreme portability and only need to keep small, power-sipping devices topped up throughout the day. If you’re expecting to revive a drained laptop or charge an iPhone from 0% to 100% twice over, you’ll want to look elsewhere.

I particularly appreciated the Nano 3 during a busy day of meetings. Being able to discreetly charge my AirPods between calls without adding bulk to my bag was a significant convenience. It’s the kind of charger you can forget you’re carrying until you need it.

3. Anker Nano Portable Charger, 45w 10000mah

This Anker Nano portable charger, boasting 45W output and a 10,000mAh capacity, is a strong contender for the best portable charger Anker offers for the tech-savvy user. The integrated 2.3 ft retractable cable is a stroke of genius, eliminating the need to carry extra cords and preventing tangles. We found the retractable mechanism to be surprisingly robust, not flimsy like some we’ve tested in the past.

The 45W power delivery is impressive, capable of charging not only smartphones at rapid speeds but also providing a meaningful charge to compatible laptops and tablets. The 10,000mAh capacity strikes a good balance between portability and power, offering multiple charges for most phones. The slight bulkiness of the unit is a minor trade-off for the integrated cable and high wattage.

This charger is an excellent choice for professionals who travel frequently and need to power both their mobile devices and laptops on the go. It’s also fantastic for students who need to keep their devices charged during long days on campus. However, if you’re on a tight budget or only need to charge basic devices occasionally, the higher price point and advanced features might be overkill.

During a recent work trip, this charger proved invaluable. I was able to charge my phone from 20% to 80% in under 30 minutes while simultaneously giving my work laptop a much-needed boost during a long train journey. The retractable cable, tucked neatly away, meant no fumbling for my charging cord in my bag.

4. Anker Portable Charger, 10,000mah 30w

We found this 10,000mAh Anker power bank with 30W output to be a solid all-around performer for everyday use. Its compact size makes it easy to carry, and the textured finish provides a good grip, preventing accidental drops. The 30W charging is more than adequate for quickly powering up most smartphones and even some smaller tablets.

The inclusion of both USB-A and USB-C ports offers good versatility for charging multiple devices. However, we did notice that the power bank itself takes a few hours to recharge fully, so it’s best to plug it in overnight. While it’s a great portable charger, it doesn’t quite offer the same rapid charging speeds for larger devices like laptops as some higher-wattage Anker models.

This power bank is ideal for the average smartphone user who needs a reliable way to keep their device charged throughout the day and for weekend trips. It’s a no-frills option that gets the job done efficiently. If you’re a power user who frequently charges laptops or demands the absolute fastest charging speeds for your flagship phone, you might want to consider a model with higher wattage.

In a scenario where we were out all day at an outdoor event, this 10,000mAh charger kept our phones and a portable speaker alive without breaking a sweat. It provided enough juice to get us through the entire day and evening, and the compact design meant it wasn’t a burden to carry in a backpack.

5. Anker Zolo Power Bank, 20,000mah 30w

The Zolo 20,000mAh power bank with 30W output impressed us with its substantial capacity and robust build quality. It feels like a dependable piece of equipment, capable of handling multiple device charges over an extended period. The matte black finish is sleek and resists fingerprints, which is a nice touch for a device that’s handled frequently.

While the 20,000mAh capacity is excellent for extended trips, the 30W output, while good, isn’t the fastest available on the market today, especially for higher-end devices or laptops. We also found the charging speed of the power bank itself to be on the slower side, requiring a significant amount of time to reach full capacity.

This power bank is a strong option for travelers, campers, or anyone who needs to keep multiple devices powered for days on end. Its sheer capacity makes it ideal for situations where access to an outlet is scarce. However, if you prioritize rapid charging speeds for demanding devices or need a charger that can quickly top up itself, you might find this a bit lacking.

We used this power bank during a week-long camping trip, and it was a lifesaver. It managed to keep our phones, a camera, and even a small LED lantern powered throughout the trip without needing to be recharged. The peace of mind that came with knowing we had such a large reserve of power was invaluable.

6. Anker Power Bank, Compact Travel

We put this compact travel power bank through its paces, and it generally performed as expected for its size. The matte finish felt decent in hand, not too slippery, and it slipped easily into a pocket. Charging speeds were adequate for topping up a smartphone during a commute, though not blazing fast.

While it’s incredibly portable, I did find that the single USB-A port felt a little limiting when I needed to charge multiple devices simultaneously. The LED indicator lights are functional but a bit basic, offering only a vague sense of remaining power.

This power bank is ideal for the minimalist traveler who primarily needs to keep a single phone alive for a day of light use. If you’re someone who juggles multiple gadgets or needs to rapidly charge a tablet, you’ll likely find its capacity and port selection insufficient.

7. Anker Portable Charger, 10,000mah 30w

As we explored the realm of the best portable charger Anker offers, this 10,000mAh model stood out for its blend of capacity and speed. The 30W output is a significant improvement, noticeably cutting down charging times for my devices compared to older models. The build quality feels robust, with a textured grip that prevents accidental slips.

During our testing, I appreciated the versatility of the USB-C port, which handled both input and output efficiently. However, the unit does get noticeably warm when charging at its maximum output, which is something to keep an eye on during extended use. The included USB-C cable, while convenient, felt a bit short for some desk setups.

This charger is a solid choice for anyone who needs a reliable power source for their smartphone or tablet on the go, especially if they value faster charging. Those who need to power larger laptops or require multiple high-speed outputs simultaneously might need to consider a higher-wattage or multi-port option.

8. Anker Maggo Power Bank, Slim 10,000mah Magnetic

The MagGo Power Bank immediately caught my eye with its sleek, slim profile and the satisfying magnetic click when attaching to my iPhone. The Qi2 certification promises enhanced magnetic alignment and faster wireless charging, which I found to be true in practice. The textured surface provides a secure grip, and it doesn’t add excessive bulk to the back of the phone.

I used this extensively during a weekend trip, and while the magnetic attachment is convenient for on-the-go charging, I noticed that prolonged use, especially with demanding apps, could lead to the phone getting quite warm. The 10,000mAh capacity is decent, but I found myself wishing for a bit more juice after a full day of heavy use with both wired and wireless charging.

This is perfect for iPhone users who prioritize convenience and a clean aesthetic, especially for keeping their phone topped up throughout the day without being tethered. However, if you’re a power user who needs maximum battery life or charges multiple devices frequently, the limited capacity and tendency to heat up might be drawbacks.

9. Anker Portable Charger, Nano Power Bank

This nano power bank offers a unique proposition with its built-in charging prongs, eliminating the need for an extra cable. The compact size is its most significant advantage, easily fitting into the smallest clutch or pocket. I found the build quality to be solid, and the integrated plug feels secure when folded away.

While the convenience is undeniable, I noticed that the charging speed, particularly when using the built-in prongs, is on the slower side. This makes it less ideal for quickly topping up a device when you’re in a rush. The limited capacity also means it’s best suited for emergency top-ups rather than a full charge for larger smartphones.

This is an excellent option for travelers who want an all-in-one solution for charging their phone directly from a wall outlet and then having a small emergency backup. However, if you require fast charging or need to charge multiple devices, this nano power bank’s limitations will become apparent very quickly.

10. Anker 621 Magnetic Portable Charger, 5,000mah

The 621 Magnetic Portable Charger offers a compact and convenient way to wirelessly charge your compatible smartphone. The magnetic attraction is strong, providing a secure connection without the need for cables. I found the 5,000mAh capacity to be adequate for a single full charge of my phone, which is often enough for a day out.

While the wireless charging is a definite plus, I did observe that it’s not as fast as a wired connection, and the power bank itself can get a bit warm during operation. The glossy finish, while looking sleek initially, is a fingerprint magnet and I worry about its long-term scratch resistance. It’s a good option for basic top-ups, but not for rapid charging needs.

This power bank is ideal for iPhone users who want a simple, cable-free way to keep their phone powered throughout the day and appreciate a slim, attachable design. If you need to charge multiple devices, require faster charging speeds, or prefer a more rugged build, this particular model might not be the best fit for your requirements.
