Anker Prime Vs. Zmi No 20 QB826G Review: Which is better?

In today’s review, we’ll be comparing two heavyweight contenders in the power bank arena: the time-tested ZMI Power Pack 20 QB826G and the brand-new Anchor Prime Power Bank.

Both come with hefty claims about their performance, promising high power levels and impressive charging capabilities. Join me as we delve deep into their specifications, testing their power output, energy storage capacity, and charging speed. Check out the latest prices here: Anchor Prime Power Bank and ZMI Power Pack 20 QB826G.

ZMI Power Pack 20 QB826G: The Powerhouse

The ZMI Power Pack 20 QB826G is a versatile, worldwide edition laptop power bank boasting a capacity of 25,000 milliampere-hours. With a maximum power delivery of 100 watts on its single port, and a total output of up to 210 watts, this power bank certainly means business.

Upon unboxing, the ZMI presents itself with a sleek and advanced design. It offers both Power Delivery and Quick Charge capabilities on three ports, supporting a wide range of voltage outputs. Notably, it features a Programmable Power Supply mode, enabling voltage options of 11 and 20 volts.

However, it’s important to note that the ZMI does have limitations. It falls short of Samsung’s 45-watt super-fast charging, and its claimed 210-watt total output power was not entirely achievable in testing. Despite this, the ZMI Power Pack demonstrated impressive efficiency, with a minimal 19% power loss at 50 watts output.

Anker Prime A1336: The Compact Dynamo

The Anker Prime A1336 boasts 20,000 milliampere-hours of capacity and a commendable 200-watt output. This power bank is packaged in Anker’s signature retail box, exemplifying their commitment to quality presentation.

Like the ZMI, the Anker Prime supports a range of voltage outputs, ensuring compatibility with various devices. However, it falls short of providing Samsung’s 45-watt super-fast charging due to a limitation in Programmable Power Supply mode.

During testing, the Anker Prime exhibited a commendable charging speed, achieving a full charge in approximately 1.5 hours. However, it’s worth noting that its displayed charging percentage can be misleading, as it maintains 100% for a substantial period while still charging at a reduced rate.

Comparative Analysis

Both power banks exhibit noteworthy features and limitations. The ZMI impresses with its efficiency, delivering power to the output with only a 19% loss at 50 watts. On the other hand, the Anker Prime boasts a compact form factor and an efficient charging cycle.

In terms of density, both power banks stand out in terms of power density, allowing for fast charging and discharging. However, it’s crucial to remember that these high figures often pertain to short-term capabilities, and prolonged use at such levels can lead to overheating.

Value Assessment

While both power banks deliver on their claims, they come with a premium price tag. It’s important to acknowledge that the extra features they offer are often short-term or marketing gimmicks. Neither power bank consistently operates at their maximum rated speeds.
