The portable power bank market is filled with boring, heavy bricks. Most of them care only about big numbers instead of how you actually use them every day. If you buy a standard high-capacity battery, you always have to carry thick external cables. They roll around on your desk when you plug in multiple devices. Even worse, they hide their digital screens the moment you lay them flat. The JOYROOM PODIX PR70 enters the market to fix these exact annoying problems. It is a highly visible, stable powerhouse made for people who work out of coffee shops, airport terminals, or busy remote desks.
I tested this unit over several weeks of heavy daily use. It is very clear that this battery pack targets a specific group of users. It aims directly at owners of high-power laptops and multi-device setups who want desk stability just as much as raw power. While most popular brands build tall, vertical blocks that easily tip over, Joyroom rethinks the physical layout. They offer an alternative that feels much more natural when resting flat next to your laptop.
Summary
- Two smart screens: It features dual TFT displays, with a front screen for vertical standing and a side display for laying flat so you can see your data at any angle.
- Built-in dual cables: It has two integrated cables of different lengths—one shorter 1ft (32cm) cord and one longer 2.3ft (70cm) cord—that save desk space.
- Massive power output: It supports dual-device fast charging, with the retractable USB-C cable delivering up to 140W and the built-in carrying cable delivering up to 100W.
- Large verified capacity: It features a clear 25,000mAh capacity that generally meets the carry-on requirements of most airlines.
- Heavy build: It weighs much more than standard pocket batteries, making it a tool for your backpack rather than your pocket.
Design and Smart Desk Layout
The look of this device immediately sets it apart from traditional portable chargers. Most power banks force you to prop them up or pick them up just to see how much juice is left. This chassis changes that by working perfectly in two different positions. The outer shell has soft, anti-slip silicone pads on its wide side. When you place it flat on a desk or an airplane table, these pads anchor the unit securely. It will not slide around when pulled by thick laptop cords or sudden movements.
The dual TFT display design fixes a truly common hassle. When you lay a standard vertical power bank flat to keep it from falling, the main screen usually points straight up at the ceiling. That means you have to lean way over your desk just to read the numbers. The PR70 includes a secondary side screen that faces you. It remains perfectly readable from a normal seated position when the unit is lying down. The glossy finish across the screen elements looks very clean out of the box, but it loves to collect fingerprints. It can also pick up small scratches if you toss it into a bag next to loose keys or metal adapters.
Joyroom builds two cables right into the frame, but they are not identical. One is a shorter 1ft (32cm) cable designed for close-range device stacking, while the other is a longer 2.3ft (70cm) cable that gives you a bit more reach. They pull out smoothly without snagging and snap back into their slots comfortably. This lets you position the battery comfortably away from your workspace on tight tables without managing loose cords.

Fast Charging and Power Output
The internal hardware supports a massive 240W total output, making its charging speed a standout feature. Thanks to this heavy-duty power allocation, you can hook up your high-end creator laptop, a tablet, and a smartphone all at once without the charger breaking a sweat. It provides ample power headroom for demanding machines like the 16-inch MacBook Pro or heavy creator laptops. When you need to juice up the power bank itself, it supports a blazing fast 100W input that allows for a full recharge in just 2 hours from a compatible wall block.
When you connect multiple devices at the same time, the smart chip inside splits the power automatically. It also includes a dedicated low-current mode, which is incredibly useful for safely charging small gadgets like wireless earbuds, smartwatches, or compact cameras without overloading them. The screen interface makes it simple to track this power split. It avoids messy grids of numbers and uses clear, animated graphics instead. You can see your fast-charging status and energy flow at a quick glance, while smart temp protection constantly monitors heat levels behind the scenes.
Size, Weight, and Final Thoughts
Make no mistake, this is not a battery designed to slip into your pocket for a casual walk. The clear 25,000mAh capacity brings a substantial size and a heavy weight profile, meaning you will always carry it in a backpack or a laptop bag. The upside is that despite its high capacity, the device is explicitly certified airline-safe, meeting global flight regulations so you can take your workstation power into the skies.
The design shines for mobile professionals, student writers, and digital creators. If you regularly carry a laptop, a tablet, and a smartphone, the built-in cables mean you have fewer things to lose or untangle in your bag. It changes any flat coffee shop table into a clean charging station. It gives you the stability of a desktop hub with the freedom of portable power, backed by official safety certifications including CE, FCC, RoHS, and CCC.
The PR70 delivers a great experience because it focuses on how people actually use gear on a real desk (much like the smaller PODIX does). The dual screens turn a simple idea into an excellent interface feature. While standard vertical bricks are fine for casual users, this horizontal alternative wins easily if you want better visibility, varied built-in cables, and heavy-duty 240W charging capability.
You can buy the JOYROOM PODIX PR70 at an early bird price of 79$.
