Review: Amazing, but be cautious of overheating - 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
Review: Fast charging, inbuilt cables, gorgeous looks - fantastic - I can’t get enough of this power bank, it’s fantastic. It charges my IPhone extremely rapidly, far better than my previous battery pack, and has built in cables, saving me from needing to take extra cables. And the sky blue colour is gorgeous!

### ⭐⭐⭐⭐⭐ Amazing, but be cautious of overheating

### ⭐⭐⭐⭐ Reliable and fast-charging power bank
*by D***E on 17 September 2025*

I’m really pleased with this power bank. It charges my phone super fast that you can actually see the battery jumping up quickly, which is a lifesaver when you’re low on power. I was super impressed with the speed at which it charged my phone that I had to time it every time I used it. I use an iPhone and in 10 minutes, it gives me a 10-20% bump on my battery depending on how low it is. At the same time, the battery life on the power bank depletes by just 3% in that time. The large capacity means I can get several full charges before needing to top it up again, and the built-in cables plus the digital display showing the remaining battery are really handy touches. The only downside is that while it’s excellent at charging devices, it takes quite a while to recharge the power bank itself. Even with a decent charger, you’ll need patience. It’s also a bit heavier than smaller models, but that’s to be expected with the bigger battery. Overall, it’s a reliable, high-capacity power bank that does exactly what I need. Just plan ahead when it comes to recharging the unit itself.
