Good quality
I’ve been using this power bank for a few days now and I’m really impressed with the performance. The build quality feels premium and sturdy, not cheap plastic. It charges my phone very fast and supports fast charging properly. The battery backup is also excellent. I can charge my phone multiple times on a single full charge, which makes it perfect for travel and daily use. The LED indicator/display is accurate and helpful to check remaining battery percentage. It doesn’t heat up much while charging, and the ports fit tightly without any loose connection. Overall, it’s totally worth the price. Highly recommended if you are looking for a reliable and good quality power bank 👍

Overall great quality and works very well
What a wonderful product, it is like a powerhouse brick but feels weightless and also handy, comes with a great power that can also charge laptop with a quick speed, all sort of connectivities available. Havent really experienced heating issues yet so far.

Worth it
Quality is awesome, loved the grains texture, it's silver color which is very unique, i thought product will be same as shown like office white which I don't like. Thank you @stuffcool totally worth it. It is bulky but does the job.

Poor reliability and dangerous
Stops working once the power indicator goes below 2 lights (basically stops working below 25%), which defeats the whole purpose of buying a 20000mAh power bank. Apart from that, it doesn't charge itself when you connect a device to it. For example, if I connect the power bank to a power source and simultaneously connect my phone to one of the ports, only the phone will charge up, the power bank wont. It does have fast charging capabilities but on the whole it has been a disappointment. Maybe the company should spend more on their technology and get the basics right rather than spending a ton on instagram reels and marketing. Update : The power bank has bulged dangerously and is a fire hazard. Please don’t but this.

A Reliable Powerhouse for All Devices
I recently purchased the Stuffcool 65W Power Bank, and I’m thoroughly impressed with its performance. It supports Type-C charging laptops, Android phones, and iPhones seamlessly. 🔋 Tested Devices: • Lenovo Thinkpad: Charges smoothly without any interruptions. • Samsung S23 Ultra: Shows Super Fast Charging 2.0, indicating high-speed charging capability. • iPhone 16 Plus: Achieved a solid 30-32W output, which is close to the maximum supported wattage for iPhones. ⚡ Performance: It delivers on its 65W promise, making it ideal for travel or everyday use. The Type-C PD output ensures quick and efficient charging across a wide range of devices. ✅ Pros: • Genuine 65W output • Works perfectly with Type-C laptops • Delivers super fast charging for Android • Optimized for iPhone fast charging as well • Sturdy build and compact design ❌ Cons: • Slightly bulky (understandable given the capacity) • Price may be on the higher side for some, but worth it for the performance

Fast charge is good
Works great with 65watts laptop can charge laptop for 2 time or mobile for 4 times. But take more time to recharge it which was fine I think, doesn't looks fancy or techie but it does the job really well.
