NICE Bank - Plenty of power, super quick charging - PERFECT for travel and multiple devices
I've had the chance to really use this battery and couldn't be happier. This is a solid unit and very easy to use. With all of the wireless devices we have around us constantly needed to be recharged I was so happy to find a bank with all of the attached cables, and it has everything I need for my earbuds, laptop, work and personal phones. Since opening it's worked exceptionally well charging several items at once, the refresh/recharge rate is lightning fast. Can be replenished/recharged quickly. The amount of power lasts significantly longer that my previous bank so looking forward to using off grid camping this summer. Super sleek design and clearly a beefy portable power pack but I'll trade a little weight for simplicity, because I can't tell you how many cables I have either forgotten or left behind. I'm very happy with the price point and feel just the simplicity alone is worth every penny.

A powerhouse for all my devices—this is the last power bank you'll ever need!
A powerhouse for all my devices—this is the last power bank you'll ever need! This portable charger is an absolute lifesaver, and its 50,000mAh capacity is no joke. It keeps my phone, tablet, and other devices charged for days on end, making it an essential companion for camping trips, long flights, or even just a busy day of errands. What makes this power bank so impressive: Massive Capacity: With 50,000mAh, it can charge my iPhone 16 numerous times over, giving me weeks of worry-free power on a single charge. I no longer have to hunt for an outlet. Convenience at its best: The built-in cables are a game-changer. I never have to worry about forgetting my charging cables again. The variety of built-in connectors (Lightning, USB-C, and more) means I can charge virtually any device, and the extra ports mean I can share the power with friends. Blazing-fast charging: The 22.5W PD USB-C port charges my devices incredibly quickly, getting my phone's battery back to a high percentage in a fraction of the time compared to a standard charger. Charge everything at once: The multiple inputs and outputs are a huge bonus. I can charge up to six devices simultaneously, which is perfect for family vacations or when I'm working with a lot of gear. Feature-packed design: The LED display is a nice touch, giving me an accurate readout of the remaining battery level. This eliminates the guesswork and gives me complete control. If you are looking for a reliable, feature-rich, and high-capacity portable charger, your search ends here. This device has truly exceeded all my expectations and is the best power bank I have ever owned.

Great looking, solid design, cost effective
This is a BIG battery, kinda heavy but I knew this when ordering. Has all the adapters needed to charge all my devices, no worries if you have the correct plugs. Charges my phone 3 times from about 15% to full at fast charge. Would buy again. Con: its kinda slow at recharging, weight. But like I said I knew this was not a small charger, fits in pocket like a phone and seems very well built. It works great, try it.

Awesome power bank, love the built in cables
Amazing back up power bank. Having built in cables was so convenient, especially when more than one kind was going to be needed. I loved not having a spaghetti of cords to carry around. A small digital display tells you how much of a charge there is in the bank while in use and goes black when idle. I got this for a trip to SE Asia and used it to power two different model iPhones and our headsets. It was awesome to have and saved us from dead batteries multiple times. It is a heavy little brick, but fit well into the power bank pocket of my back pack. I did notice that the shiny side got scratched somewhere along the way, which was surprising. I think it must scratch easily because it was usually in a bag with mostly soft items, on a table, and at worst laying on the floor next to the outlet, but with the shiny side up. There’s no display that got messed up by the scratches, it just didn’t look as nice and shiny anymore. This happened within a week of travel. Unfortunately, the power bank got confiscated at the airport security check in Siem Reap, Cambodia. They said it was over capacity. I wasn’t very happy about this turn of events, especially since I didn’t have any problems going through the airports with it in San Francisco, Hong Kong, and Vietnam. Something to be aware of, though, that some airports may have stricter limits that this won’t comply with. I like the item so much that I’ve already ordered another one. I’ll have to finish out my trip with an alternate I was able to find in Vietnam, but my replacement for the confiscated one will be waiting when I return from my travels.

Great charger
This charger routinely lasts me a week at a time. I love how many cable options it has. Unfortunately, I've had two of these now and for some reason the USB-C cable stops working after a few weeks.

Excellent Portable Charger, Truly Powerful
I’m very impressed with this power bank. The 50,000 mAh capacity is real and noticeable: I can charge my phone, tablet, and even small accessories multiple times without worrying about running out of power. The built-in cables make life so much easier since I don’t have to carry extra ones, and the multiple outputs allow me to charge several devices at once without losing speed. The digital display is very handy to know exactly how much battery is left, and the fast charging feature works great, much more efficient than other power banks I’ve tried. It is a bit larger and heavier than a regular one, but that’s totally understandable given its capacity. Overall: a powerful, practical, and reliable product, perfect for long trips or for anyone who uses their devices heavily throughout the day. Highly recommended!
