Is it normal for the charging speed to be slow?

The charging speed depends on whether the charger and cable can meet the power bank’s requirements. Using a 20W fast charger, the power bank can be fully charged in approximately 5.1 hours.

Can it charge low-current devices like earphones?

Yes, this power bank features a low-current charging mode.Simply double tap the power button to enter this mode to charge small electronic devices and double tap again to exit!

Does it support charging while discharging?

Yes, the power bank supports pass-through charging with a max input and output of 5V/3A. Note that it does not support simultaneous charging and discharging for laptops. For longevity, avoid charging your phone while charging the power bank.

How can I estimate the number of charges for my device?

To estimate charges, use this formula: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity. For example, an iPhone 15 with a 3,877mAh battery can receive about 1.67 charges from a 10,000mAh power bank (10,000mAh × 0.65 ÷ 3,877mAh).

Why is my power bank providing fewer charges than expected?

Energy loss during charging, due to inefficiencies in the battery cells and circuitry, results in a 30% to 45% capacity reduction. Therefore, a fully charged Anker Zolo 20,000mAh Power Bank typically provides about 11,000mAh to 14,000mAh.

Go Beyond with 20,000mAh: Carry the power you need to charge your iPhone 15 up to 4 times or your Samsung S24 3.79 times, perfect for extended travel and long days.
30W Two-Way Fast Charging: Charge quickly with 30W output and recharge just as fast with 20W input, keeping your devices ready in no time. Boost an iPhone 15 from 0 to 57% in just 30 minutes.
Durability on Demand: Features a 5.98-inch built-in USB-C cable that’s not only convenient but also extremely durable, designed to withstand over 10,000 bends.
Enhanced Safety: Equipped with ActiveShield 2.0 technology that monitors temperatures 3 million times per day and adjusts power output to ensure safe charging.
What You Get: Anker Zolo Power Bank (20K, 30W) with a 5.98-inch (15.2 cm) built-in USB-C cable.

Customers say

    A great product for a great price. 5/5 stars.
    The Anker Zolo Portable Charger 10,000mAh 30W Power Bank is absolutely Game changing for portable charging. The Anker Zolo has a great price on Amazon Prime for around $15 USD.The power bank features a 10,000mAh battery which can help you stay charged throughout the day and not have to worry about your battery. For those with larger devices/more devices to charge you might want to get the 20,000mAh version of the power bank. I chose the 10K mAh power bank because I don’t need to charge many devices at the same time and I don’t have a larger device that needs more power to fully charge.The Anker Zolo is great to fit in backpacks, pockets, purses, etc. There is also no need to carry around a charger if you have a device that supports USB-C charging since the Anker Zolo has a built in USB-C braided cable that is durable and short so your device can charge faster.You can charge the device using the provided USB-C cable in the box or connect the built in USB-C charger to a USB-C charger cube. I recommend using a USB-C to USB-C fast charger so that it will charge quicker and you are not waiting too long for it to charge with a regular cube.The best feature of the Anker Zolo is that the power bank has a screen that shows you how much battery is left in the power bank. There is a button on the side of the power bank that you can press and it will show you what percent it is at and it will show a lightning bolt symbol when it is charging.You can charge up to three devices at a time with the Anker Zolo. There is a USB-C port, USB-C braided cable built in, and a USB-A port for standard chargers.I decided to give the product a rating of 5/5 stars because this is such a great product especially when you can get it for such a cheap price. You can look at other Anker products and see there are portable and wireless charges that go for $40-50 with smaller battery capacities like 5,000mAh.Thank you for reading my review!

    Super fast charger for super low cost
    I got the 10,000 mah version on sale for about $15. It’s light, fairly small (about the size of a pack of cigarettes) and my phone recognizes it as a super fast charger. For what you’re getting it’s a solid battery pack, and if you find it on-sale, I don’t think you can beat it.The cable works nicely, and seems like it’ll hold pretty well. You’ll have to decide if you trust it to not come loose if you hang it on a bag or something but it does take some purposeful effort to pull loose. It would definitely work to hang on a hook or something static. I expect the cable to fail eventually like all cables do but it’s pretty solid and there is a secondary USB-C port (In/out) along with a USB-A port (Out only) so even when the cable fails the pack will continue to function so no worries there.Definitely a solid battery pack if you’re in the market for one.

    love this thing. best purchase I’ve made in a while
    i bought this for a road trip, i figured it would be nice to have a powerbank incase my phone died in Mexico or on the road. it came in handy so often, I love the built in cord, the portability, everything about it i love. it’s a little heavy, but not really that big of a problem. it works perfectly and charges fast and is so durable. I love the type c in/out and having an extra usb a port is so nice. for the price and everything I’ve recommended it to several people.

    Strong performance, design could be better
    After years of relying on my trusty 15,000mAh power bank, it was time to get another one to share the load on longer trips and busy days. I decided to pick up Anker’s 10,000mAh power bank, which seemed like a solid choice with its 30W fast charging capability and a few extra features.This power bank can charge multiple devices at once with its three ports: a USB-A, a USB-C, and an integrated USB-C cable that also works as a lanyard. It supports charging up to 30W, which is great for quickly powering devices.Design and Portability: This one feels somewhat bulkier than other 10,000mAh models. Its glossy midsection may look great at first, but this makes it a fingerprint swamp that is also prone to scratches. The integrated lanyard/USB-C cable sits neatly into the body, and won’t come loose unless with a good intended tuck. It’s compact enough for daily use, though the bulkier shape makes it less ideal.Power Delivery and Ports: It has three charging options: a USB-A port for legacy devices, a USB-C port for more modern gadgets, and an integrated USB-C cable that can be used for both charging the power bank and other devices. The total output is 30W, meaning it can charge multiple devices simultaneously, though the power will be shared between them. The built-in cable is particularly convenient when you need a quick charge on the go without hunting for a separate cable. It also has pass-through but the charging speed of your devices will dramatically slow down when the battery bank is also charging.Performance and Charging: It can charge at up to 20W, even when the battery level is at 99%, making it great for quick top-ups throughout the day. The performance matches expectations for a 30W charger.Display: There is a segmented LED display that reads the exact battery percentage – easy to track how much charge is left. It’s a simple, but doesn’t include more advanced features like “time remaining” for full charges that some of the more expensive battery banks offer.Cons: While it performs well, the power bank does have a few design flaws. It’s bulkier than other 10,000mAh models, which makes it less portable. The glossy midsection attracts fingerprints and scratches easily, so it quickly starts to look worn. It also lacks a “time remaining” feature, which some slightly more expensive alternatives include.Conclusion: This power bank ticks several boxes right – fast charging, multiple ports. However, its bulkier size, fingerprint-y glossy finish, and lack of a time estimation are personally too much of a deal breaker. If you’re focused more on performance and less on aesthetics, it’s still a decent option at only $15.

    Powerful and Convenient Power Bank!
    This Anker Zolo power bank is a fantastic travel companion. The 20,000mAh capacity easily keeps my devices charged for days. The built-in USB-C cable is extremely convenient and feels very durable. The 30W fast charging is a game-changer, quickly boosting my Samsung’s battery.I appreciate the safety features with ActiveShield 2.0. The ability to recharge the power bank quickly is also a great plus. It’s a reliable and well-designed power bank that I highly recommend.

    Bardzo fajny, pojemny. Trochę martwi mnie, że był rozładowany do 20 % bo raczej źle to wróży na temat jego trwałości

    Purchased the 10,000 mah. This power bank is great!I love the little screen that tells me the percentage of power left in the power bank! I have one without the screen and now I never question if the power bank itself has been charged.Small and light weight, slightly heavier than my cell phone itself. Comes with a type C charger built in, making it very convenient and because the cord is short, it plugs into the phone and can be carried without a long annoying cord hanging around. Charging speed seems decent as well. The battery last for about two phone charges.This was a life saver at the airport where I couldn’t find a charging outlet but had a fully charged power bank.Trusted brand name for reassurance. Highly recommend.

    Compatto, leggero e potente! La ricarica è veloce grazie ai 30W, perfetta per smartphone e anche per dispositivi più esigenti come tablet o MacBook in emergenza. Il cavo USB-C integrato è super comodo, così non devo portarne uno a parte.L’unico piccolo difetto è la capacità: 10.000mAh sono sufficienti per un paio di ricariche complete su uno smartphone, ma chi ha bisogno di più autonomia potrebbe preferire una versione con maggiore capacità

    Estuve buscando una power bank para mis salidas en la bicicleta o viajes y está me pareció muy buena, si es un poco grande para su capacidad pero no pesa y logra cargar bien mi Xiaomi a 24Watts lo que es muy bueno porque la mayoría de dispositivos así solo alcanza 12w o menos (ojo la publicación dice 30w pero esa es la velocidad máxima que puede otorgar, y está sube y baja dependiendo del nivel de batería para proteger el dispositivo como en todos).Los materiales son de plástico y su correa se sujeta fuerte reforzada con tela.
