Detailed Review

The UGREEN 145W Power Bank impresses with its robust build quality and functionality. In tests, its 145W power output was able to fully charge a MacBook Pro in just under two hours, showcasing its strength in handling high-demand devices.
The 25,000mAh capacity provides ample power, enabling a smartphone to be charged approximately four to five times before requiring a recharge itself. Despite its weight and size, which are slightly more than many portable power banks, its ability to power up to three devices at once compensates for the lack of portability.
However, the absence of wireless charging limits its flexibility. Ideal for tech-savvy travelers and professionals who need dependable power on the go.

The power bank's 10,000mAh capacity allows for approximately two full smartphone charges, providing peace of mind for extended trips. Its compact and lightweight design makes it a convenient travel companion without adding bulk.
However, the power bank requires around four hours to recharge completely, which may be a consideration for those needing rapid turnover on-the-go. Despite lacking wireless charging capabilities, its multi-port design offers great versatility, making it a practical choice for users with diverse charging needs.

Users can expect a reliable fast charge experience with Quick Charge 3.0, significantly reducing downtime with a 50% battery boost in just 30 minutes. This battery can power a standard smartphone multiple times, making it a strong companion for camping or extended outdoor trips.
However, its solar panel, while a great feature for emergency situations, does not charge rapidly unless in direct, strong sunlight. Additionally, its size may deter those looking for an everyday portable power bank.
Despite these limitations, it remains a top choice for those needing a robust, high-capacity solution.

Weighing only 150g, it's ideal for users needing a lightweight power solution. The robust carbon fiber construction protects against drops and impacts, ensuring durability.
The power bank's dual USB ports enable simultaneous charging of devices, though the 18W limit may not fully satisfy users with laptops or power-draining gadgets.

Detailed Review

The INIU Megapower 10000 is a practical choice for those who value portability and efficiency in a power bank. During testing, it consistently delivered a 92% conversion rate, which means most of the power stored is effectively transferred to your devices.
The device supports two simultaneous charges through its dual USB ports, making it convenient for users with multiple gadgets. However, its reliance on a Micro USB input for charging slightly hampers its own recharge speed, taking approximately 5.5 hours to fully charge from empty.
Despite lacking USB-C output, which would have allowed for faster charging, the power bank compensates with its accurate LED display, showing the precise power level remainingโ€”an insightful feature for managing charge cycles effectively. The device's compact form factor is designed with portability in mind, making it an ideal companion for travel or everyday use.
While the absence of USB-C might deter fast-charge enthusiasts, the INIU Megapower 10000 maintains a solid performance balance for most general needs.

Detailed Review

The Anker Prime Power Bank stands out for its substantial 20,000mAh capacity, which provides enough power to recharge a standard smartphone multiple times, making it ideal for extended trips without access to an outlet. In terms of build quality, the power bank feels solid with a sleek design, but it is larger in size compared to other options at its capacity, potentially posing a challenge for those needing compact solutions.
Real-world testing shows its 60W output performs excellently in rapidly charging not only smartphones but also larger devices like laptops, delivering a versatile power solution for demanding users. Its dual-port design includes both USB-C and USB-A connectors, ensuring compatibility with a wide range of devices.
However, its size and premium price might not fit everyone's needs, especially for buyers seeking the smallest form factor or more budget-friendly options.

The Goal Zero Flip 24 is a well-engineered power bank designed for users who need reliable power on the go. With its 6,700mAh capacity, it efficiently charges smartphones up to 2.5 times, making it ideal for short getaways or camping trips.
The USB output with 2.1A allows for decent charging speeds, while the sturdy build can withstand outdoor conditions. However, its single USB port limits the ability to charge multiple devices simultaneously.

Detailed Review

The Anker 737 Power Bank (PowerCore 24K) excels with its 24,000mAh battery capacity, which is perfect for those who need to charge multiple devices on the go. In real-world tests, it successfully powered a MacBook Pro for more than one complete charge while still having juice for additional phone charges.
With a maximum output of 140W, it enables rapid device charging, supported by Power Delivery 3.1 and Quick Charge 4.0 compatibility, making it an essential accessory for professionals and travelers alike. Additionally, its solid construction suggests long-term durability, though this comes at the cost of being heavier than average power banks at around 1.4 pounds.
While the power bank is on the pricier side, its capabilities and build quality justify the investment for those regularly demanding high power output. However, its reliance on USB-C ports may require users with older devices to carry adapters.
