### ⭐⭐⭐⭐⭐ Amazing, but be cautious of overheating
*by J***H on 11 April 2026*

This is one of the best charging blocks that we’ve come across. It’s pretty hefty and is heavier and thicker than our phones but it’s sturdy as hell! It looks sleek and smart and being able to see the charge remaining on the back in big OLED numbers is great! No more more carrying around 3 separate wires for my phone, partners phone and our son’s tablet, this has all three chargers that we need! It will charge my just my partners iPhone 11 or just my son’s kindle fire hd10 about 2-3 times before it needs charging again. Unfortunately it will only charge my power hungry iPhone 17 pro max 1-2 times before needing charging again. It charges relatively quick and if we but it on charge before we go to bed, it is done by morning. Honestly it’s so great that since getting my power hungry phone we’ve bought a second of these so that my phone can have one and my partner and son can use the other. It charges stuff much faster than regularly. The ONLY small downside of this power bank is that we’ve found that because it charges stuff so quick both the bank and whatever we are charging get very hot and before we knew how hot it was, it actually burned my skin. So we have to be careful about what surfaces we charge on and we make sure that the power bank and device aren’t stacked to try cool them down a bit
