Power banks serve as essential backups for mobile devices, offering reliability during unexpected battery drain, especially away from charging sources. They provide security and reassurance without requiring a high investment, though selecting a quality option justifies a modest upgrade.
Among various models owned, the Anker Zolo stands out as the preferred choice for daily carry. This device features a 20,000mAh battery, a common size in the market. Smaller 10,000mAh versions suit those seeking compact, budget-friendly options under $20, but 20,000mAh meets the needs of most users effectively. It sustains a smartphone's power throughout the day, including during intensive tasks like gaming sessions in Hearthstone.
The reviewer's Samsung Galaxy S24+ boasts a 4,900mAh battery, allowing the Anker Zolo to deliver approximately four full charges under ideal circumstances, despite the often inflated capacity claims of power banks. It has proven useful for topping up wireless earbuds during outings and reviving a low-battery Kindle, though the latter rarely requires it due to its long-lasting design.
With 30W Power Delivery output, the Anker Zolo offers solid charging performance, though not the quickest available. According to the manufacturer, it can reach 50% charge on a phone from empty in roughly 30 minutes, aligning with practical observations.
What elevates the Anker Zolo above others is its integrated 6-inch USB-C cable, eliminating the need for an extra cord in most scenarios. A separate cable is only necessary for simultaneous charging of multiple gadgets, such as during travel, facilitated by the unit's USB-C and USB-A ports that support up to three devices at once.
Additionally, the embedded cable functions as a handy strap for transport. Initial concerns about its durability with the 0.8-pound unit proved unfounded; it withstands attachment to a belt loop at events like concerts, remaining secure and intact.
While not the most lightweight option, its heft aligns with the substantial 20,000mAh capacity. For a slimmer alternative, the 10,000mAh model offers reduced size and weight. Ultimately, the larger version fits the reviewer's requirements ideally.
