Very good power bank, 20000mAh is enough for many charge. Built-in 4 cables is so useful, no need carry extra. Fast charging work good for my phone and tablet. Not heavy, easy take in bag. Black color look nice. Recommend!

This portable battery is an ideal size: it's about as large a capacity as you can take on to an aeroplane, but physically is a nice size and a shape that would slip into a pocket or bag very nicely. It has a reassuring (but not back breaking) weight, it feels solid and well constructed.The Charmast displays battery charge as a percentage which is much better than the 3-4 little winking lights many other batteries have. The display is located under the surface of the battery case, which is cool. It also has a little green symbol which lights up when quick charge is engaged.The battery uses USB-C for fast charging up. It has two charging USB-A outputs and one quicker charge USB-A socket (colour coded for easy of recognition). You can also quick charge a device via the USB-C socket.This means you can a total of four devices on charge at once! If you charge multiple items you lose the ability to quick charge, but this is a reasonable tradeoff for being able to charge four devices at once (I'm doing this now with a phone, a tablet, a digital camera and a pair of headphones, and it's working flawlessly).There are safety circuits to prevent overheating (the battery did not appear to warm up noticeably while working) and also turns off charging when you devices are full.Battery life seems to be about right for the stated capacity, but I will wait to see how it beds in over repeated cycles.All in all this a a fabulous piece of kit for a very reasonable price, especially when its on offer via Amazon. Recommended!

A fantastic charger, this is the 3rd one I've bought as every member in our family now have one each! Not too heavy in comparison to others I've bought in the past but works like a charm. It will charge my phone 3 times easily, generally lasts me a good 5-7 days to charge my phone and vape a few % to last me the day without having to recharge. Chargers pretty quickly as well!

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.

The best thing about this charger is that it holds it's charge well with no noticeable discharge when not in use.I fully charged this power bank before leaving the UK and it has lasted five days before depletion. Over the five days this power bank has been charging two high end smart phones, a tablet and an electric lighter. It is currently being recharged from a solar power bank so the solar product is being charged by the strong African sunshine whilst also charging this power bank back to it's full capacity.As thos roduct has a high storage capacity it performs very well and it is reliable so it's excellent for travelling with.There are similar products available that have larger capacity but the 23,800mAh that this one holds is more than adequate as there are many, many products of only 10,000mAh with little difference in price this this is good value. Should you be seriously considering a new power bank I can recommend this one as it is well built to a good quality standard, it is strong, has a high capacity and delivers good value.

This Power pack has saved my life a few times and it's brilliant!I charge it up then I take it with me and depending on how long my rubbish phone battery lasts its great to have thisEasy to use, attached cables are brilliantVery happy with product quality and looks ☆☆☆☆☆
