VIYISI Power Bank 30000 mAh 22.5W Fast Charging Battery Pack USB C Portable Charger with 4 Outputs & 3 Inputs for Samsung iPhone iPad Android PhonesCarbonfree Certified

Best portable charger I've ever had.Bit of weight but nothing insane, bit big but again nothing insane. Neat little screen, and very durable. I've had this charger for a year or so now and it's had decent use and I'm pretty rough with my electronics and other than a couple scratches from dropping it a couple times it's still ok.Super fast charging (with red usb) has 3 ports, 2 blue and one red, and all three types of charging ports to charge itself as shown in picture. Battery life is really good, went on holiday for a weekend and only used 20%!!I've had alot of portable chargers in my time, and for this price I'd buy this again if I needed!Mine went down to 21% as shown in the image, and that's after I went away for a week in May and haven't needed to charge it since, and during that trip I probably used it for 24+ hours.I don't often write reviews unless I'm super impressed.

Excellent at powering up various bits of kit. It will take a while to charge up, as can be expected with such a powerful device. It packs a lot of juice!Do be aware that it is around 3 times heavier than a lesser 10000mA model. (300g seems to equate to10000mA in most brands.)It's solidly built, has all the ports you're likely to need and charges up your devices at a good pace. Recommended.

Fantastic power bank and great value for money. Took a long time to fully charge but did expect that. Managed to charge my devices for the second half of a festival and still came home with it half full. Quite heavy so not ideal for carrying around.

This this is a beast. Lasts change early charges my phone 8-10 times. Does take a while to charge the actual power bank but just use a fast charger

UPDATEAfter my review the company contacted me and arranged for me to receive another unit, which is working fine. I'm really impressed by their customer service, and the second unit I received is working absolutely fine. In fact it's better than most as you can charge multiple items simultaneously on the go. I'm a travel writer so that's quite useful at coffee stops etc. So, if anyone else has problems with theirs, let them know. Hopefully mine was a one off, but their customer service is responsive.Avoid. I have several power banks and this is the worst. Only had it working once giving about a phone's worth of charge. Takes hours and hours to recharge and now its not working at all. Sadly I gave it another go by trying to charge it and it took me out of the return window! Going to have to bin it and get a different one.

I wouldn't bother with this item. Firstly the ports. It comes with 3 USB-A (the big ones), 2x USB-micro (old fashioned D shape), and only 1x USB-C (the small ones). Considering how many devices use USB-C these days, that's just weird. Not only that but it claims to do Super fast charging (PD/QC), but using a cable and a ph(Theone that supports super fast charging on other devices, it won't do super fast charging. It also doesn't seem to accept super-fast charging on the input port. The input port is the USB-C port, so can't super fast charge and charge with a USB-C at the same time, so, back to weird choice of ports given that so many devices are USB-C.It is claimed that it has 30k mwh storage, but I have a 10k mwh battery which does super fast charging and will charge phones 5x, and weirdly the percentage on this device seems to drop so fast that it wouldn't support 15x charges to the same device.I would have returned it but it arrived the day before a holiday and it was bumped and banged around, so I'm going to accept it as a loss. I was hoping for a beefier version of my existing battery, but alas no. It is heavy, but without the benefits of being able to Quick Charge two devices at the same time.Not worth the money.

Why did you choose this product over others?:This powerbank is amazing! It's heavy... but its quality and keeps all your devices fully charged.You don't need to worry about dead phone/device battery with this!

I just got it today and I’m just wondering how long it takes to fully charge the actual portable charger , it’s been in about 3 hours so far and it’s gone up 10% so will it take over 2 days to fully charge? Also do you get a good charge out the first charge or do you have to charge it twice for the full experience? Like you usually have to do for other things. I need it for a 4 day trip and wouldn’t like it to die on me ahaha
