Charmast Power Bank 30000mAh, 20WPD QC 3.0 Quick Charge Portable Charger with 2 Inputs & 3 Outputs USB C Battery Pack Compatible with Smartphones Tablets and More

I bought this power bank in April 2022. It is still working at 100% efficiency. I recommend it to users who need power delivery. I monitored my iPhone battery health during the last 12 months while using this power bank, and thank the manufacturer and seller, the battery health was not decreased as many power banks did. Don't hesitate to purchase this product. I will be a life time customer of Charmast.

This is my second Charmast power bank, I had to give away the first one to someone because they liked it very much! So here I am again, this power bank works perfectly, it’s heavy duty and one charge can recharge your devices multiple times. Personally I use it to charge my iPhone and iPad, and I can say it’s the best you can buy! Warning; It’s a bit heavy!

Good for travelling

worth buying it, very good quality and perfect power charging. little heavy weight but that doesn't matter...

its takes a while to charge up to 100 %. i use this to charge my phone when i travel and i use a samsung s22 ultra.it charges my phone in like 45 to 60 mins. that from 10 to 100 %. and it does that atleast 3 times before running out of juice.its slightly heavy but not that bad. comes with a little back pouch and build quality is great. i would definitely recommend this.

This is an amazing battery backup! It's extremely well built, slim, and lightweight. It has LED battery level indicator which is very useful and has several ports that enable me to charge multiple devices at the same time. I could tell this thing is so quick and powerful!

After 3 months of use , it stopped charging from all ports specialy usb , and not compatible with super fast charging cables!!!I am requesting either replacement or refund!!!!

This is the best Power Bank i have bought , once fully charged you can use for days. not too big or too heavy. great choice
