Anker's product department seems to be working overtime, it seems. The company just unveiled the 10,000 mAh Zolo power bank, and now, a fresh leak has revealed that Anker is working on a successor to its popular 621 Magnetic Battery 5K (currently $39.99 on Amazon). The new model, A1667, will feature a 5,000mAh battery, a bidirectional USB-C port, and 15W Qi2wireless charging. These specifications hint at a daily-driving, compact power bank, akin to a lot of other Anker products in this range, but its super-slim design could make it stand out in the catalog. Instead of an LED display, the portable form factor utilizes battery LED indicators.

One of the main advantages of a slimmer design like the A1667 is its portability. A thinner profile will let users fit the power bank easily in their pockets or bags. It also offers the convenience of wireless charging, with the added benefit of being Qi2-certified for faster charging speeds. However, the slim form factor won't be without its limitations. A 5,000mAh capacity, while enough to charge one smartphone, limits the power bank's ability to fully recharge larger devices like tablets or some high-capacity smartphones. Furthermore, heat management can become more challenging in slimmer devices, which may lead to performance issues during high-output wireless charging.

In comparison to Anker's bulkier models like the MagGo Power Bank 6.6K, the A1667 may not offer as much juice, but its ultra-thin design could make it an appealing option, specifically for those who prioritizing portability over capacity. Depending on how Anker balances these trade-offs, it'll be interesting to see how this Qi2 portable charger performs in the market.

Speaking of Qi2 chargers, Anker's15W Qi2 MagSafe power bank with an adjustable stand is still at its lowest-ever price of $29.99 - you can check out that deal here.
