Charmast Power Delivery Power Bank 26800mAh, PD Power Bank, 18W USB C Portable Charger Quick Charge 3.0 Battery Pack Compatible with MacBook, iPad, iPhone, Samsung, Pixel, More Phones, Tablets

I have a 3 yo iPhone 8plus which the battery doesn't last a full day anymore. Even working from home now, it is a pain to plug it to the wall charger and wait it to get charged for hours; of course not to forget leaning and stretching to check the msgs, reply to them or answer incoming calls. Considering the new phone prices and power bank prices, buying the power bank was the solution for me to extend the lifespan of my phone and postpone the expensive investment on a new phone.I preferred this power bank because of the maximum capacity being allowed on a plane, but most importantly, its own ability to get charged by a USB-C, Lighting Cable and the old micro USB. It indeed is a luxury not to carry a second charging cable on the go just to take care of this device and being able to charge it with whatever cable you can find if you don't have one with you. It does get charged from the Micro USB, Lighting and USC-C ports. And it charges your phone from USB-C and 3 other USB ports.I bought this power bank on September 2020 and I have been using this power bank since 5 months now. Since I got this device, I am charging my phone only with this. After fully charged, this battery charges my iPhone 8plus four times, from below 10% to 100%. It does have some more juice to charge another half time but I rather kill the power bank than the phone itself. I always charge the power bank after the fourth time, it takes an overnight duration for the power bank get fully charged. No complaints on that, rather the power bank than the phone. This is a heavy item, heavy as a battery should be, no complaint on that either. If anything can be said about it, I wish it was slightly narrower. Not easy to hold it behind the phone, which is narrower than the power bank, while making a phone call.Unfortunately this device does not come with a USB-C to Lighting cable, but I got a one foot one and using it all the time. That enables me not to deal with a long cable and carry the phone and the charger with me while charging the phone. Very convenient and highly recommended. Moreover, the USB-C port does give you the fast charge, which is a breeze, in comparison with the charging times by using the original wall plug iPhone provides. I don't know if it is mentioned on the product description but if not, hear it from me: it doesn't charge your phone while it is getting charged itself. I did try to charge two phones at the same time and it does work no problem.So far it is a nice one. I will update my review after some time and if anything unexpected happens to it.Update September 2021: Now I have been using this power bank since one year. Took a plane with it several times without a problem at the airport. I have been charging my phone more than 1 time with this charger, it is heavily used and charged every three days. It still charges my Iphone 8 Plus from 10% to 100% four times. Its battery didn't degrade, all its ports are intact and I have had no problems with it. Highly recommended.

The Charmast Power Delivery Power Bank turned out to be a very useful especially when I traveled abroad. The device held a charge for week(s) without using it, and I was able to charge devices 4 or 5 times before needed to recharge the power bank (being fully charged of course).It is weighty and solid, but was not an issue for me. It has a variety of common connector ports including an orange USB slot for 12V devices like iPads or fast charge devices. Also, it automatically turns on when you plug in a device, and starts charging. It will also automatically shut off when complete or if you accidentally leave it on. It has 4 tiny LED indicators for battery life, which is nice.My one small annoying issue is the tiny side button to turn the power bank on/off. It blends in with the case, is very small, and hard to see (especially if your sight is not great). I end up have to look on both sides, flipping it around each time to find the side it's on. It would have been a huge help if the button was orange or yellow - something to stand out from the solid black. I ended up using a silver Sharpie to mark a dot on each side next to the button so I can immediately see where it is (see photo). Not a deal breaker by any stretch.Bottom line is I love it, and use it all the time. I highly recommend this.

Since my iPhone's (6 plus) battery has consumed power so quickly (need to charge it at least four times a day), I decided to buy a high capacity power bank, which has a high-speed charge function and high power capacity. I have been looking for a satisfying power bank, but I couldn't find it until I got this one. It contains many ports so that it allows me to charge multiple devices at the same time, with three USB ports (one for QC 3.0, a high-speed protocol, and two for 2.0). As the description mentioned, it is able to charge up 50% in 30 mins. (The USB-C port is versatile, also with QC 3.0 protocol that means it will charge your compatible devices with the optimal charging speed, For example, Boost up 50% battery to your iPhone X/ 8/ 8 Plus in 30 minutes.). When I test it to charge my iPhone with QC 3.0 port, it truly took only 30 mins to charge my iPhone 6s to 60% from 13%. In addition, its high power capacity allows me to charge my iPhone to 85% more than four times from 10%-20%, and there is still power left. Besides, I love its shape, not very light, but it is thin, therefore it's very easy to carry in my backpack. Overall, I am happy with it. By the way, I am not a prime member, but it still took only one day to deliver to my house. Perfect express service.

This works well. I do feel like it juices out decently quick. It takes a while to fully charge. I like the size of it.
