The JP350 Power Bank has exceeded my expectations in every way. The built-in display is extremely useful — it doesn’t just show the percentage of charge left, but also the watts going in and out. With a second press of the power button, it reveals even more information, including the unit’s temperature in both Fahrenheit and Celsius. It’s rare to see a power bank with such a detailed and informative readout. One of my favorite touches is the pull-out USB cord. It retracts automatically, making it incredibly convenient and eliminating the need to carry extra cables. The top-mounted USB-C port is another great feature — it works both ways, allowing you to charge your devices from it and also recharge the power bank itself through the same port. Alongside that, there’s also a USB-A port for added flexibility when charging multiple devices. With its generous 20,000mAh capacity, this power bank easily keeps my gear running through long trips, power outages, and everyday use. The build quality feels solid, the features are genuinely useful, and everything performs exactly as advertised. Highly recommended — this is one of the most convenient and well-designed power banks I’ve owned. Read more
This power bank is so useful! It’s relatively cheap compared to similar brands. It charges itself and other devices extremely fast! It seems very durable and I love the addition of the phone holder and its high charge capacity, and how easy it is to use. Read more
It works as advertised. I’m using it on a 2025 MacBook Pro M4. Specs I lack because I keep my device at 100%, I know weird for some but it’s an acquired convenience. Size is perfect 5in height and 21/2in width all 4 sides. Charges up quick, depending on your wall plug wattage. Weight is comfortable in the hand and barely noticeable in a case or book bag.

Very good power bank so far. Not at all disappointed, rather extremely surprised on how well it works. Functionality is great, 2 USB C fast charging for my Surface pro 9 & 2 USB C Super fast charging for my Galaxy S24+. Capacity is also awesome. 27,000 mAh. It also comes with retractable USB-C cable that is long. It's a great buy... Highly recommend... Read more

Very powerful charger. I can charge an iPad and iPhone at the same time and have plenty of battery left. Charging the power bank does take some time but definitely worth it. Read more
