With enough juice to charge an iPhone 11 over 8 times, this hefty power bank aims to provide maximum power on-the-go. But does bigger necessarily mean better? Let’s take a look at what customers on Amazon have to say about the pros and cons of this supersized power solution.


First and foremost, users rave about the enormous 27000mAh capacity of this RAVPower power bank. For many customers, this is the main selling point – with this much power, you can easily keep multiple devices charged while traveling or during a power outage without having to recharge the power bank itself for days. Reviewers love that they can “charge everything at once” with the 3 USB output ports. The high capacity also provides peace of mind during long trips off the grid. As one user put it, the RAVPower 27000mAh is like “having a wall outlet in your pocket.”

In addition to the huge capacity, customers find that the power bank charges their devices surprisingly fast. Although a 27000mAh power bank would normally recharge at a slower rate, RAVPower’s use of advanced charging technology allows this model to power up phones and tablets faster than lower capacity power banks. Several reviews mention how the high speed-charging combines with the large capacity to allow charging multiple devices super fast.

The LCD display showing remaining battery percentage is another well-liked feature, allowing users to accurately monitor how much juice is left. And the sleek, portable design gets high marks despite the large battery size inside. Users comment that the power bank feels sturdier and more premium than cheaper models thanks to the aluminum alloy exterior.

When it comes to value, customers feel that the RAVPower 27000mAh delivers plenty of power for the price point. Many reviewers compare this model favorably to more expensive power banks with similar capacities. Overall, the combination of huge capacity, fast charging speed, and reasonable price makes this a top choice for customers looking to maximize their power on the go.


Need Massive Power On-the-Go. : The RAVPower 27000mAh Power Bank May Be the Solution

The most common complaint about the RAVPower 27000mAh is unsurprisingly its bulky and heavy body. While some customers don’t mind the weight in exchange for the massive capacity, others feel it’s too heavy for comfortably carrying around. As one user put it, “This thing weighs as much as a brick.” So if you’re looking for an ultra-light and compact power bank, this isn’t the best choice.

In a few isolated cases, users found that the power bank stopped working properly after 6 months or a year of heavy use. Yet the overwhelming majority of customers rave about the durability and say the internal battery still holds a charge for years. So quality control issues seem very minimal.

Some criticisms focus on the design lacking pass-through charging, which would allow charging the power bank and connected devices simultaneously. Others felt the charging speed, while fast, was still slower than wall outlet charging on certain devices. But most found the recharge times very reasonable.

While the RAVPower 27000mAh isn’t perfect for everyone, it hits the key needs for portable power users. The massive capacity, multiple output ports, LCD display, fast charging speed, and reasonable price combine to deliver on the promise of power anywhere.

While the size and weight may deter some who prefer ultra-compact designs, the trade-off for the enormous 27000mAh capacity is worth it for many power users. With enough juice to recharge an iPhone over 8 times, or provide multiple full charges for phones, tablets, and even many laptops, this supersized power bank provides peace of mind for off-grid use.
