Anker Zolo USB C Charger Block 2-Pack Review: Honest Analysis

Overview

The Anker Zolo USB C Charger Block 2-Pack offers a straightforward solution for anyone needing to charge multiple devices without breaking the bank. Priced at just $29.99, you get two chargers, each with 2 USB-C and 2 USB-A ports capable of a combined 50W max output. Anker is a trusted brand in the charging space, and the Zolo series aims to deliver reliable performance at a lower cost than their premium GaN lines. But is this 2-pack a true bargain or a compromise? Let's find out.

Specifications and Power Distribution

Each charger in this pack has a total output of 50W, which is shared among the four ports. When using a single USB-C port, you can get up to 30W, enough to charge an iPhone 16 or Samsung Galaxy S25 series at full speed. The second USB-C port, when used alone, also supports up to 30W. However, when both USB-C ports are in use, the power is typically split (e.g., 25W+25W or 30W+20W depending on the devices). The USB-A ports max out at 12W each, and adding any USB-A port will reduce the power available to the USB-C ports further. This is crucial: the 50W is not per port but a pool. If you need to fast charge a MacBook Air (which can pull 30-45W), you can do so when only the laptop is plugged in, but adding another device will slow it down.

Build Quality and Design

The chargers feel solid for their size. They use a matte white plastic that resists scratches fairly well. The plug is fixed (not foldable), which may be a minor inconvenience for portability but keeps the cost down. The ports are clearly labeled and spaced enough to accommodate most cables without interference. Anker claims a 'stable design' and indeed the chargers stay planted in the outlet thanks to their weight distribution and non-slip bottom. They don't wobble even with two heavy cables attached. However, unlike Anker's GaN series, these run noticeably warm under load, especially when using multiple ports for extended periods. This is normal for traditional silicon chargers but worth noting if you're used to cooler GaN devices.

Charging Performance

In real-world use, the charger performed as expected. Charging an iPhone 16 from 20% to 80% took about 45 minutes using a single USB-C port, which matches the 30W speed. Adding a second device, such as a Samsung Galaxy S25, on the other USB-C port slowed the iPhone to around 18W, extending the time to about an hour. The USB-A ports charged an old iPhone 12 at 10W and a pair of AirPods at 5W. For a typical evening setup (phone, watch, earphones, and tablet), the charger can handle all four, though the tablet may charge slower than expected if the laptop is also plugged in. This is the key limitation: the 50W total means you must prioritize which devices you want to charge quickly.

Comparison to Alternatives

The Anker 735 (GaNPrime) is a single 65W charger with three ports (2 USB-C, 1 USB-A) and is better suited for those who need to charge a laptop at full speed while also topping off a phone. However, it costs nearly $46 and is only one charger. The RavPower 65W offers a higher total wattage in a single unit for a similar price, making it better if you often need to power a laptop plus other devices. The Zolo 2-pack excels in value for money if you want dedicated chargers for different rooms or bags and don't demand high wattage from every port simultaneously.

Pros and Cons

• Pros: Affordable 2-pack; compact design; two USB-C ports; stable in outlets; reliable Anker brand.
• Cons: 50W shared limits per-device speed; USB-A ports slow; runs warm; no foldable plug.

Who Should Buy This?

Best for: Users who need a simple, cheap way to charge multiple low-power devices (phones, earbuds, tablets) at home or in the office. Also ideal for travelers who want to leave one charger at home and take another without worrying about cost.

Skip if: You need to fast charge a MacBook Pro or Windows laptop at full speed while also charging other devices. Also skip if you prefer a single compact GaN charger that can handle a laptop and phone simultaneously at higher wattage.

Final Verdict

The Anker Zolo 2-Pack 50W Charger delivers on its promise of convenient multi-device charging at a budget price. It's not the fastest or most feature-rich option, but for the price of two chargers, it offers tremendous flexibility for households or travelers on a budget. If your needs are modest and you understand the 50W power sharing, this is an easy recommendation. For those with higher power demands, spending a bit more on a GaN or higher-wattage single charger may be wiser. Overall, a solid 'Buy' for the intended use case.
