Anker Zolo Power Bank (2025 Upgraded Version), 20,000mAh 30W High-Speed Portable Charger with Built-in USB-C Cable, Battery Pack for iPhone 17/16 / 15 Series, Galaxy, and More

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.

Man, this Anker Zolo 20,000mAh power bank is seriously built like an absolute tank. It features a super smooth, slick design that just feels premium in your hand, but it’s tough enough to take a beating without skipping a beat. One of the coolest design choices is the built-in USB-C cord that comes right out of it, so you never have to scramble around looking for a loose cable. Plus, it has a physical button to click it on and gives you two extra USB-C plugs right on the frame so you can hook up multiple things at once. For how inexpensive this thing is for the sheer quality you get, it’s just an excellent choice all around. ​I’ve been taking this thing all over town inside my backpack, and it has been super convenient for keeping my gear alive while I’m on the move. Since I use my phone a ton out on the streets, my battery tends to die pretty quick, but this brick completely saves the day. This massive 20,000mAh capacity easily lasts me through 4 full charges before the bank itself runs out of juice. You get a ton of heavy-duty uses out of it on a single charge, making it a reliable backup generator when you’re out running errands or working a long shift. ​When it does come time to feed the power bank or top off, it charges up incredibly fast. It doesn't waste any time pushing power through the lines, which is perfect when you need a quick boost. It’s Inexpensive, it looks totally cool, and it delivers elite performance without breaking the bank. If you need a rock-solid portable charger that you can just throw in your pack and forget about until you need emergency power, you definitely need to grab one of these.

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.

Very good quality. Pretty hefty, but slim enough to fit in bags. It powers my phone and all my cameras without a sweat, and I usually have about 50-60% by the end of the day on the charger. It's nice to have too much than too little! It charges really quickly, just about as fast as when I plug it in the wall at home. Has an extra usb-c cable but I only use the built in cable. I do not like carrying cables. Despise carrying cables, in fact. But the wireless chargers aren't efficient enough and don't charge camera gear. This goes with me everywhere.

It seems a little heavier than I expected, but it isn't bad. I like the way it looks, the charged level of the battery itself and the built in charging cable. My iPhone doesn't report Fast Charging when I used it, but it is charged to 80% which may account for that. I would recommend this charger.

Small, simple to use and packs a good amount of power. This charges my Samsung Galaxy S25 Ultra almost 2 times 0% - 100%. That's enough power to get me through roughly 36 - 48 hours without my phone getting dangerously low. I recently bought this since the one I had for a few years finally gave out. I wanted something small and portable friendly without the bulk. This checked every box. The built in cable Is great. You get super fast charging. I can go from 5% up to 100% in just over an hour with minimal use while charging. LED screen with percentage power remaining is a great feature. Always know how much power you have left. Didn't feel it get hot while charging my phone.

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

The built-in USB-C cable makes this my go-to option for power on the go. The display is easy to read, the capacity will let me keep a phone charged all day, and the 30W is enough to deliver a quick charge. I've even used it to extend the battery life of a power-hungry Dell laptop when I forgot the laptop's charger on a trip. The digital display is handy, too. Further, it's small enough to slip into a pocket or carry in a backpack without weighing me down. One dislike is that, if I plug a low-power wall charger into this device, it will only deliver the output of the wall charger, not the full 30W.

bueno, mucha bateria, carga rapido

Super batterie. Un peu lourde mais hyper efficace. Chargement tél très rapide . Pour recharger la batterie externe un peu longue mais c'est normal. Dragonne sur la batterie, très pratique pour mettre en charge le téléphone. Il y a l'affichage du niveau batterie 🔋. Je l'a recommande et en ai même acheté 2 😉

Sehe sehr gute Power Bank.
