Charmast 26800mAh Slim Portable Charger Power Bank, 15W Fast Charging Battery Pack, Travel Essentials Compatible with iPhone 16/16 Pro/16 Pro Max, iPhone15/14/13/12 Series, iPad, Samsung etc

I bought this back in 2023 and used it up until 2024. It’s a great charger, never failed on me. It works with everything. One time I used it to charge my laptop as it died on me during class. Anyways I lost the powerbank. I would highly recommend it. It’s a bit heavy and bulky but you can’t complain because it holds a lot of power.

Used this on a trip to Japan — placed in my carry-on luggage to power the external ports. It is slim and easily packed. Just as important, it delivers a quick charge.

This battery backup deserves a great review. It's got a sleek but not polished exterior finish so it won't slide out of your hand. It was a very decent price point. I personally have really appreciated the slim design to where it can fit into my utensil pocket on my lunch bag. Lastly after 2 years I've had 0 issues with this and it gets used atleast a few times a month if not more.

Purchased in July, I used it every single day through December and it worked great until mid December when it completely died and would not turn on or charge. I contacted Charmast and they immediately responded that the unit had failed and they would refund, I received a full refund a few weeks later. For 5 months it worked wonderfully as my Quest 3 backup battery enabling me to play as long as I desired. I would have tried this one again but needed a backup right away while waiting on a refund.

Sleek. Works so far. Will see next month if it goes through TSA in the carry-on. TSA rules say this should meet the requirements.

I cannot give this portable charger enough stars!!!I have had so many chargers over the years (so have my kids) and they were complete garbage- no matter what size, type, or brand...they always died (didn't last more than 6 months, if that), and often wouldn't completely recharge a phone when it was on its last bar.With those experiences, I had not expected a lot out of this one... However, I was incredibly happy with the purchase!I have had it for nearly two and a half years now, and I am not easy on it... I take it with me everywhere and I use it in my home as well throughout the day.I'm running a Google Pixel on it and would typically use my fast charging cord... But if I don't have it or it's not handy, this charges up my phone even while I'm using the phone (and does so quite quickly)!I love that it's flat and it came in its own little (microfiber) pouch when I bought it. (It is a little heavier in weight than I'm used to, but it's not a drawback, just something to get used to.)I use this portable charger for other things as well! It has several ports.I love the color of it, that's just a bonus.It does look dingey now, especially around the edges even after cleaning it it doesn't go away. Some of the scuff marks will not come off just due to the type of material it's made out of but that's not a drawback for me at all. I'd rather have a dirty charger that works this well and this long, than a piece of junk that doesn't.When I charge this unit, then leave the house for the day with a fully charged phone and blow through my cell battery, I ALWAYS know as soon as I plug this into my phone I'm back in business (and oftentimes it will charge my phone completely, even if I'm using it, and I still have battery power left in the portable charger)!If you're looking for your favorite portable (quality) charger, I'd recommend this one.

So far so good. Most critical reviews complain about the size or weight or charging time. These all are due to the batteries capacity and safety for charging. I wouldn't trust anything smaller to have the capacity or anything not costing much, much more to charge any faster safely. While 26,800 seems unlikely (someone who took one apart said it was actually only 20,000mAh), it does hold a lot of power and seems well made. From the reviews the failure rate seems relatively low. The smooth texture is somewhat non-slip. The color-coding of the USB A ports are confusing; USB 1 (blue) is 5V-2.4A, USB 2 and 3 (blue and orange respectively) are both 5V-3A. Huh?

Works great. Holds a lot. Charging speed is quick. Good value for my hard-earned money. Provides enough power to charge my multiple devices while long-distance hiking. Really like it, and yes, do recommend.
