I recently purchased the Anker 335 Power Bank (PowerCore 20K) and I have been extremely satisfied with its performance. The portable charger is compact and lightweight, making it easy to carry around with me wherever I go. It has a 20,000mAh battery capacity, which is more than enough to charge my phone multiple times before needing to be recharged itself. One of the standout features of the Anker 335 Power Bank is its 20W power delivery capability. This means that it can charge devices at a much faster rate than other portable chargers on the market. I've found that it can fully charge my phone in just a couple of hours, which is a significant improvement over other portable chargers I've used in the past. In terms of build quality, the Anker 335 Power Bank feels solid and well-constructed. It has a sleek and stylish design, with a matte black finish that looks great and doesn't show fingerprints. The power button and USB ports are easy to access and use, and the included micro-USB cable is of good quality. Overall, I'm extremely happy with my purchase of the Anker 335 Power Bank. It's reliable, fast-charging, and well-made, and I would definitely recommend it to anyone in need of a high-quality portable charger. Read more
Fantastic portable power source. Charges my phone quickly and multiple times between charges. It's heavy, but that's to be expected given the power it packs. It's larger than my phone, but worth the weight! Read more
This is my second one. My first was lost on a PrincessCruise ship and never returned. Charger is heavy but last long especially since the iPhone chargers don’t last long after a while. Read more
The Anker Power Bank (20,000mAh) is a fantastic portable charger that’s great for keeping all my devices powered up on the go. The 20,000mAh capacity is perfect for multiple charges, whether I’m using it for my iPhone, iPad, or even my Apple Watch. It charges quickly, thanks to the USB-C fast charging, and I’ve found it to be super efficient—usually getting me through a full day of heavy use without needing to recharge the bank itself. The size is ideal—not too bulky, so it fits comfortably in my bag or even my pocket if needed. The build feels solid and durable, which is always a plus with portable chargers. The only downside I noticed is the battery indicator LEDs are a bit dim compared to my other Anker power banks. It’s not a huge deal, but it can be hard to read the exact charge level in some lighting. That said, this is a minor inconvenience compared to the overall performance, which is excellent. If you’re looking for a reliable, fast-charging power bank with a high capacity, this one’s definitely worth it. It’s perfect for anyone who needs a dependable charging solution for their phone, tablet, or other devices. Read more

It's not often that a product exceeds expectations to the point where it deserves a rating beyond the standard 5 stars, but the Anker Power Bank 20K has done just that. With its remarkable performance, sleek design, and user-friendly features, it has earned a well-deserved 6-star rating in my book. Durable Design with a Modern Twist: As someone who has owned a previous Anker power bank, I was already acquainted with the brand's commitment to quality. However, this updated design takes the cake. Its build exudes durability, ensuring that it can withstand the rigors of travel and daily use. The sleek white finish is not only aesthetically pleasing but also resistant to wear and tear. Dual USB Ports and USB-C Fast Charging: The inclusion of two USB ports is a game-changer. It allows for the simultaneous charging of multiple devices, making it an ideal companion for those who travel with various gadgets. The USB-C fast charging capability is a notable upgrade, ensuring that your devices are powered up swiftly and efficiently. User-Friendly Charging Status Indicator: Reading the charging status has never been easier. The clear and intuitive indicator lights keep you informed about the power bank's remaining charge, eliminating any guesswork. This feature is a testament to Anker's commitment to user convenience. Impressive Charging Capacity: The true strength of this power bank lies in its capacity. During a full charge, it provides enough power to recharge your laptop once and your cell phone up to four times. This level of versatility is particularly valuable for those who are constantly on the go, ensuring you stay connected without interruption. Quick Shipping and Unmatched Quality: Anker's reputation for quality and reliability is well-deserved. Your expectations are not only met but exceeded.
