Powerful portable charger!
**Power Bank / Portable Charger 22.5W Fast Charger – A Must-Have for Any Device User!** I gave several of these Power Bank 40000mAh Portable Chargers as stocking stuffer / Christmas gifts, and they were a huge hit! For under $30, they offer incredible value. What I love most is that they come with adapters for all types of devices: iPhones, Androids, laptops, video game controllers, and wireless headphones. It was a perfect for my family, as it works with both old and new devices—no need to worry about missing cables! While it is a bit bulky, it's the only portable charger I found that can handle everything we need. Plus, it has a very bright flashlight, which would definitely be useful in case of a power outage. **Pros:** - Works with ALL devices, old and new (Type A, Type C, Micro Cable, Lightning Cables). (USB in & out) - Has digital display showing % available. - Holds charge for a long time and takes DAYS to drain to 0%. [Auto shut-off when its 100%] - Very bright flashlight, useful in emergencies. - Great for charging laptops, phones, game controllers, and headphones. - Excellent value for under $30. - Comes with a one-year warranty. **Cons:** - A bit bulky, so not the most pocket-friendly option. - Takes at least 8 hours (overnight) to charge fully. - Gets warm during use or charging; place on a flat surface to help with cooling. Overall, this charger is a practical and well-loved gift for my family. [I have to order more!] It’s PERFECT for anyone who needs to keep multiple devices charged on the go and is a great option any time of the year. Highly recommend it for anyone looking for a reliable portable charger.

High-capacity charger with great features, some trade-offs
I recently purchased the Power Bank 40000mAh Portable Charger with 22.5W fast charging, 5 outputs, 2 inputs, LED display, and built-in flashlight, and overall, it’s been a reliable companion for my charging needs. Here’s my take after using it for a couple of weeks: Pros: • Massive Capacity: The 40,000mAh capacity is a game-changer. It easily charges my iPhone 16 and Samsung Galaxy multiple times on a single charge, making it perfect for long trips or heavy usage days. I’ve also used it to power my tablet and Bluetooth headphones simultaneously without breaking a sweat. • Fast Charging & Versatility: The 22.5W fast charging works as advertised, juicing up my devices quickly. The five output ports (including USB-C and USB-A) and two input options make it incredibly versatile, allowing me to charge multiple devices at once. It’s compatible with both my iPhone and Samsung, which is a big plus. • LED Display: The LED display is a standout feature. It accurately shows the remaining battery percentage, so I’m never left guessing how much power is left. This is super handy for planning recharges. • Built-in Flashlight: The flashlight is a nice touch for emergencies or camping. It’s bright enough to be useful in a pinch, like during a power outage or when navigating in the dark. • Safety Features: It feels secure to use, with built-in protections against overcharging and short-circuiting. My devices have had no issues while charging. Cons: • Size and Weight: While it’s marketed as portable, the 40,000mAh capacity makes it bulkier and heavier than smaller power banks. It’s not something I’d slip into a pocket—it’s more suited for a backpack or bag. This isn’t a dealbreaker, but it’s worth noting for those prioritizing ultra-portability. • Recharge Time: Recharging the power bank itself takes a while, even with a fast charger (around 10-12 hours for a full charge). This is expected with such a high capacity, but it can be inconvenient if you need to top it up quickly. • Air Travel Restriction: The 40,000mAh capacity exceeds TSA’s 100-watt-hour limit (roughly 27,000mAh), so it’s not allowed on airplanes. This limits its usefulness for frequent flyers. Final Verdict: This power bank is a beast for anyone needing a high-capacity, multi-device charger for travel, camping, or emergencies. The fast charging, LED display, and flashlight make it a practical choice, and it handles my iPhone 16 and Samsung Galaxy with ease. However, its size, long recharge time, and air travel restrictions keep it from being perfect. I’d recommend it for heavy users who prioritize capacity and versatility over portability—4 stars for delivering reliable power with a few trade-offs.

Sturdy, convenient, dependable
Works well. Love the attached cords. I can charge my iPhone and Mac book and still have 40% charge left on the power bank. It comes it very handy on trips. It's quite heavy and bulky compared to others, but I think it's because it holds a lot of power!

Great but takes forever to charge it…
Works good, could probably get about 3 and a half charges out of it, more if you use your original cord…. (Faster charge when you use your original cord). Slow to charge everything if you use the attached cords, also VERY SLOW to charge the power bank it self…. I mean really slow… it got down to 13% and I plugged it in, been 24 hours and it’s only at 60%… lol So it’s great, but better have some time to get it charged cuz will probly take 2 days to charge it back up… Heavy but not too bulky,
