As someone who has used both the Anker 321 and 621, I can confidently say that both of these portable chargers are essential in my daily life. However, each one serves a different purpose and has its own unique features that make it necessary to have both in my possession.

Firstly, the Anker 321 is a smaller and more compact charger that is perfect for on-the-go use. Its lightweight design makes it easy to carry around in my bag or pocket, making it convenient for traveling or running errands. Additionally, its capacity of 5200mAh is enough to fully charge my phone at least once, providing me with a reliable backup power source.

On the other hand, the Anker 621 is larger in size but has a significantly higher capacity of 20100mAh. This makes it ideal for longer trips or situations where I know I will need multiple charges throughout the day. Its multiple USB ports also allow me to charge multiple devices simultaneously, making it perfect for group outings or family vacations.

Moreover, both chargers have unique safety features such as surge protection and temperature control, ensuring that my devices are charged safely without any risk of damage. This gives me peace of mind knowing that my expensive devices are in good hands.

In conclusion,

My Buying Guide on ‘Anker 321 Vs 621’

Introduction

As a tech enthusiast, I have always been on the lookout for the latest and most reliable gadgets in the market. When it comes to power banks, Anker has always been my go-to brand. With their wide range of products, it can be quite overwhelming to choose between two of their popular models – Anker 321 and Anker 621. In this guide, I will share my personal experience with these power banks and help you make an informed decision on which one is best suited for your needs.

Design and Build

Both Anker 321 and Anker 621 have a sleek and compact design, making them easy to carry around. The Anker 321 has a rectangular shape with rounded edges while the Anker 621 has a more square-shaped design. Both power banks have a matte finish that gives them a premium look and also prevents fingerprints.

One noticeable difference between the two is the LED indicator lights. The Anker 321 has four dots that indicate the battery level while the Anker 621 has a digital display that shows the exact percentage of battery remaining. Personally, I prefer the digital display as it gives me a more accurate idea of how much charge is left.

Battery Capacity

The battery capacity is an important factor to consider when choosing a power bank. The Anker 321 has a capacity of 10,000mAh while the Anker 621 comes with twice the capacity at 20,000mAh. This means that the Anker 621 can charge your devices multiple times before needing to be recharged itself.

Another advantage of the higher capacity in the Anker 621 is its ability to charge larger devices such as tablets or laptops. With its PowerIQ technology, it can detect and deliver optimal charging speed for various devices.

Charging Speed

Both power banks support fast charging technology but there is a slight difference in their output. The Anker 321 has an output of up to 2.4A while the Anker 621 offers up to 4A output. This means that the Anker 621 can charge your phone or tablet at a faster rate compared to the Anker 321.

In my experience, I have noticed that my devices charge significantly faster with the Anker 621 compared to using other power banks or even charging directly from an outlet.

Additional Features

Apart from charging your devices, both power banks come with some additional features that make them stand out from other brands in the market. The Anker PowerCore+ series (including both models) supports pass-through charging which means you can charge your devices while simultaneously recharging your power bank.

Another noteworthy feature of both models is their safety features such as surge protection and short circuit prevention which ensure that your devices are protected from any voltage fluctuations while being charged.

Price

The price difference between these two models may vary depending on where you purchase them from but generally, there is about a $10-15 difference with the Anker 621 being slightly more expensive due to its higher capacity and additional features.

Conclusion

After using both power banks extensively, I would highly recommend either one depending on your specific needs. If you are looking for a compact and portable option with enough capacity for daily use, then go for the Anker PowerCore Slim (321). However, if you need more charging capacity or want faster-charging speeds then investing in an upgrade to the PowerCore+ (621) model would be worth it in my opinion.

Overall, both models offer great value for money and are reliable options when it comes to portable chargers. I hope this guide helped you make an informed decision on which one suits your needs best.
