Great Product but false advertising
Edit 1: Okay, I think the product has a rating way too low that it should. It's not a bad product. I really enjoy using it. I charge most of my devices with it and it's a good quality product. So I am giving it 4 stars so more people would actually buy it. For my original review, see below. Original review: Been using it for over a month now. The build quality is fantastic. But it doesn't deliver on the input and output wattages. Max input charge is 12V and 1.5 amperes. That's around 18Watts. So it charges slowly. Takes hours. Output is good. But maxes out at 12V and 1.8A for all devices, which is around 23 watts for mobile devices and 20V and 1.8A for laptops. (Not sure if we can charge the power bank with 2 inputs at once. Haven't tried it. Maybe that'll charge it fastly). My phone takes 120 watts charging but the battery bank doesn't charge the phone at 100 watts. It's the total power delivery when multiple devices are being charged at once. So 100w fast charging is false advertising. It works well on apple laptops or any laptop with usb-c pd port. It charges my macbook seemlessly. No issues there. There's a power button on the device but I have no idea what it does. The manual doesn't tell what it does either. But if you need good battery bank with robust build quality and good capacity, then you can definitely buy this one. But if you're expecting 100w fast charging for a single device, then you'll be disappointed. And the warranty registration is a beeeze and they'll give you a 6 month extended warranty over the 1 year warrenty if you register it within a week of purchase.
