I’ve actually owned the first version of this battery pack, and the difference with this newer model is immediately noticeable. The original one I had was significantly bigger and bulkier, so I was honestly surprised (in a good way) that this updated version is much more compact while still delivering the same performance and specifications. It feels like a true upgrade rather than just a refresh. From what I experienced, the older, larger version was eventually recalled, so it’s reassuring to see that this newer model not only addresses those concerns but improves the overall design. Performance wise, it does exactly what you want from a high quality battery pack. It charges devices quickly and consistently, holds a solid charge over time, and is reliable when you need it most. I’ve used it for my phone and other devices, and it handles multiple charges without any issues. A few things I really like: • Much more portable and easier to carry around compared to the previous version • Solid build quality that feels durable and well made • Fast and efficient charging • Great capacity without the added bulk • Perfect for travel, work, or just keeping in your bag for everyday use Overall, this is a big improvement over the original. If you were hesitant because of how bulky older versions were, this one fixes that completely while still delivering the same power. Definitely worth it. Added photo next to wallet for scale

I’ve been using this Anker power bank for about 2 years now, and it’s been very reliable. It’s taken a decent amount of abuse drops, travel, even camping trips, and it’s still going strong with no issues. The built-in USB-C cable makes it super convenient since I don’t always have to carry an extra cable with me. Battery performance has also been good. Even if I leave it unused for a while, it still holds its charge pretty well and doesn’t drain quickly. I’ve actually bought a few more for friends when they were on sale, and they’ve all had good experiences too. Overall: Great power bank, especially if you can get it on sale.

I've used, and have overworked this thing for two years now. Battery capacity is awesome, I'm able to keep my phone charged throughout my 12hr shifts with no problems. The unit itself isn't heavy, or all too big, and the built-in cable is convenient for both charging your phone and charging the battery pack itself. The pack itself charges my phone real fast, and when it comes to charging using a wall plug, it charges real fast too. At 30W, it's about as fast as you need it to be, I'm able to use my phone to 0%, and have it fully charge twice using this pack, it is no slouch when it comes to power delivery. The on-screen display also makes it very convenient to quickly check how much juice it has left. This thing is also built like a tank, I've dropped this thing more times than I'd like to admit, and it has no visible scratches or impairment to its operation. This will continue to be my daily driver for the next couple years hopefully.

I’ve been using this ANKER portable charger consistently and it’s solid across the board. Durability is on point, it feels sturdy and not cheap at all, I throw it in my bag daily and it holds up. The built-in cord is short but that’s actually perfect for portability, it’s made to charge while you’re holding your phone or keeping it in your pocket, not stretch across the room. Connectivity is smooth, once you plug it in it starts charging instantly with no disconnect issues. Compatibility is easy, works perfectly with my USB-C devices without any extra setup. The charger quality feels premium, no overheating or slow charging. As for power capacity, it gives me a full charge with some power left over, which is clutch for long days out. Overall it’s compact, reliable, and gets the job done.

This battery pack is impressive for the price - I got it for just $20. The charging speed is fast, it feels well-made, and the attached cable works well and seems like it won't wear out. The capacity isn't the largest out there, but it seems to match the spec of 10k mAH, so that's nothing to complain about. Charging my phone from empty uses more than half of the battery. The main complaint I would have is that the shape isn't ideal. It's narrower than most battery packs, but also thicker. Carrying it in your pocket is not difficult (for men's pockets), but it's a bigger bulge than most. Also, if you want to hold it behind your phone in order to use your phone while charging, the fit is less comfortable. Overall, while I like Anker as a brand and I think they made a good product, I might consider other versions.

this charger is honestly SO good. i’ve used a lot of portable chargers before and this one is easily one of the best. i charged my phone from around 25–30% all the way to 100%, and the battery pack was STILL at about 80–90% after. that’s actually crazy. it literally lasts all day and sometimes even DAYS depending on how much you use it. one of my favorite features is the built-in cable. it makes everything so much easier because you don’t have to carry extra cords around or worry about forgetting one. super convenient, especially when you’re out. i also LOVE the display that shows the exact battery percentage. it’s way better than guessing with little bars because you always know exactly how much charge you have left. it charges fast, holds a lot of power, doesn’t overheat and is just really reliable overall. perfect for everyday use, traveling, or being out all day.
