This product is great due to the fact that I can recharge my Galaxy Note 9 from 20% to 100% on normal charge for up to 6 times. Also, the fast charging features are great for an emergency. Given it has a large battery capacity, the unit size is large, which is understandable, the unit is well built. Highly recommend this battery pack for anyone who looking to extend their device battery usage for days.
This power bank is really impressive. You get so many charges out of it. It's great to have the USB-C port. I've been able to charge my Pixel 2, Nintendo Switch, MacBook Pro (2018) as well as anything else my friends and families etc. have thrown at it. It's sizeable and heavy but that's what comes with the large capacity. I like the fact that it auto turns on/off once you connect/disconnect your devices to charge.
I purchased this battery pack mainly to power my Dell XPS 2-in-1 (9365) which requires USB-C PD 30W. Thus far it's worked very well and can also charge up my iPhone XS (USB-C to Lightning) very quickly. Downsides are it's a little bit bulky and heavy but then again at 26800mAh, you'd expect it to be. Does take a while to charge the battery itself, but I just leave it charging overnight. Would have been good if it also came with a USB-C charger to charge the battery pack.
Had this power bank for 3 months, bought it with a special price, very happy with the purchase, charged my switch on the run, speedly charged my 2 phones at the same time (one PD, one ismart), turf build, only tiny problem is the usb-c cable come with it, some time hard to plug in my case protected S8+ as its adaptor is little bigger than normal one.
