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

Fantastic product! I have bought 3 of these over the last year or so. It has a lot of capacity and can charge phones quickly and even charge iPads quickly as well.I think the one thing to note is that you need to make sure you charge the charger with a plug that has a higher power output; a standard iPhone cube won’t cut it. I have a charging plug that has a 60W output and the charger will charge from empty to full in 3-4 hours.

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.

Este cargador es increíble, tiene una carga muy rápida, puedo cargar mi iPhone hasta 4 veces lo recomiendo mucho, creo que me compraré otro.

I bought this device after I started using my mobile phone more, including professionally, and it became important to have backup power on the go or during power outages, etc. I chose this produce both because of its high capacity and the form factor, which looked like it was probably cell-phone sized, allowing it to fit neatly behind my mobile device.The good:On the power front, it didn't disappoint - while charging this up, or while using it to charge your device, it has four LED lights indicating charge level, and it seems like each of these is good for a full cell phone charge from 0% (using a modern Google Pixel phone). So when fully charged, you can absolutely use this for your phone with no wall power for several days.It's also pleasantly thin and simple in design. It does what it's supposed to do very well and doesn't overwhelm you with unnecessary features. Using this device is essentially stress-free.The bad:I rate this overall at 4 stars because the form factor is somewhat large. Although thin, it is longer and wider than I'd like. For some people it may be fine, there are phones the size of this, but if you're like me then some phones are just too big, more closely resembling a small tablet than a phone. This is about the size of those phones. So it does not match the form factor of my phone as I'd hoped - it is not pocket size at all, and that will impact how I can travel with it. Still, knowing this I would buy it again because it works well and I know of no other better device at a smaller form factor right now.The other issue I had which was also minor has to do with the charging cables it comes with: one is the old (large) standard USB to micro USB, and the other is the old (large) standard USB to type-C. They're quite short and ideal for using this power bank to charge your device. Sadly, they're less than ideal for charging the power bank itself. It would have been good if it came with a type-c to type-c cable, since that is now essentially the new standard cable connector type, and it would be nice if that cable was a little longer than the others.Conclusion:While my pros are shorter than my cons, make no mistake this is a great device. It's just that it's easier to explain what's good about it and it takes more words to explain the relatively minor areas in which it could be improved. I would suggest this power bank for a friend or relative, and would buy again if I needed another for some reason (if four days or so of power weren't enough).

This power bank is actually better than I expected. It held a charge for days with me using it at least once a day for an hour or two before I had to recharge it.

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.

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.
