The Anker 621 Power Bank (A1645) promises a convenient and efficient charging solution for Apple devices, thanks to its integrated Lightning connector. But does it deliver on its claims? After weeks of testing, here’s my in-depth review.

The Anker 621 boasts several key features that make it stand out. The most prominent is the built-in Lightning connector, eliminating the need for a separate cable. This sleek design makes it incredibly portable – it truly fits in your pocket. The 5000mAh capacity is also a nice touch, promising multiple charges for most iPhones. MFi certification assures compatibility and safe charging for Apple products, a crucial factor for many users. The 12W fast charging capability is another welcome addition, ensuring quick top-ups.

In my testing, the Anker 621 performed admirably. The built-in Lightning connector was a game-changer, simplifying the charging process considerably. I consistently achieved fast charging speeds, matching Anker’s claims. The 5000mAh battery delivered on its promise, providing multiple full charges for my iPhone 13 Pro. I did notice a slight warm-up during extended charging sessions, but nothing alarming. The compact size is a real advantage for travel, easily fitting into a bag or even a large pocket.

During a long road trip, I relied on the Anker 621 extensively, and it consistently provided a reliable power boost. I managed to get through an entire day of heavy use (navigation, photos, messaging, and music streaming) with plenty of battery to spare. This demonstrated the power bank’s real-world efficiency.

The Anker 621’s performance exceeded expectations regarding charging speed. Its compact size and lightweight nature made it a practical companion for daily use and travel.
