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.

Worth it.
This thing is a beast. Charges very fast the device and battery last multiple charges. It’s bulky but it’s not terrible to carry around or throw in a bag. Great for travel or work or school or anything. Very good quality I recommend. It functions great.

Sturdiness and powerful.
This Anker 20,000mAh power bank has been a total game-changer for me. First off, the battery life is amazing—I can charge my phone multiple times (easily 3 full charges) without having to worry about recharging the power bank itself. Perfect for road trips, long days out, or emergency situations.The built-in charging cable is super convenient, and the LED screen that shows the exact battery percentage is a feature I didn’t know I needed—now I can’t live my house without it.It’s a bit heavier than smaller banks, but that’s expected with the power it packs. Still, it’s compact enough to fit in a pocket or backpack without being bulky. The build is premium and durable, and I love the clean, black look.Overall, this is one of the best power banks I’ve owned. Reliable, efficient, and worth every penny.

Reliable Powerhouse with Built-In Cable – Perfect for Travel
I’ve been using this Anker Zolo Power Bank daily for a few weeks, and it’s become my go-to charger. The 20,000mAh capacity easily gives me multiple charges for my phone (Pixel 7) and still has enough juice left for my earbuds or tablet.What really sets this model apart is the built-in USB-C cable—no more forgetting cords. It also supports 30W fast charging, which is enough to quickly top off my phone and even give my Steam Deck a solid boost. The pass-through charging feature is a nice bonus when I’m juggling devices.The build quality is solid—feels premium and not overly bulky for the power it packs. Fits nicely in my backpack and doesn’t overheat under load.Pros:✔ Built-in cable is super convenient✔ 30W fast charging works great for phones and tablets✔ High capacity—4+ full phone charges✔ Sleek design and durable finishCons:✘ Would love a built-in USB-A cable too✘ Slightly heavier than smaller capacity models (but that’s expected)Final thoughts:If you travel a lot or use power-hungry devices, this is an excellent investment. Anker continues to impress with thoughtful design and performance.

Good quality!
Charges my phone pretty quickly and was able to charge my headphones and my phone at the same time—using the built in cord and the small usb-c to usb-c cord included.

Good power bank before the recall
This was one of my favorite power banks until it was recalled. The cord length was prefect for charging my S22 ultra. One of the few charges that supports super fast charging on samsung phones. Great power capacity. Charges my phone in an hour from 0. Compatible with all my devices. The only reason it gets 4 stars is due to the recall. Anker quickly replaced it with a comparable model that was heavier and bigger. I appreciate the quick support from Anker but preferred this charger over the new one.

Portable and Easy to Use!
Honestly, this charger is perfect.It has a USB C cord attached to the unit, which can both charge the battery and charge your phone/tablet/etc. The USB A port on the side is a great little feature, since I have a USB A charger attached to my earbud charger case. This charged everything I needed for school and trips. This mighty guy is quite big and bulky, but can charge my iPhone 16 at least 5 times and eliminated the need to carry an extra few cords.The chord also acted a bit like a keychain, since its grip is really strong and durable. All you would really need is a wall adapter for this. This can charge in my car and charge my phone without the need for bringing anything else with me.(My JLABs have a built in cord and my hearing aid case uses USB C in the photo)

Great little power bank as well as great customer service.
This is (was) a great little power bank. Could charge my phone multiple times over and also power my laptop in a pinch via USB-C.The only quirk is that you can’t do USB-C PD output and 5V USB-A at the same time. USB-A 5v will take precedence and the USB-C output will shut off. It also cycles power to the ports if you connect another device (not a big deal unless you’re powering something power-sensitive like a Raspberry Pi from it).You’ll notice the review says it “was” a good power bank. That’s because the unit I got was recalled. While I had no issues with mine, I was notified by both Amazon and by Anker that there was a potential fire hazard with a limited batch of products and that this one was affected.The replacement process was extremely painless, and I had the new one direct from Anker within 3 days of submitting the claim. A+ for the customer service there.Unlike the many no-name power banks you can buy, when a potential fire hazard was identified with these, they were prompt to address it. That speaks very well of the manufacturer, and I will continue to praise Anker in that regard.As a bonus, the model they replaced it with is actually nicer than the one I bought, so absolutely no complaints from me.

Très satisfait de cet achat, chargement rapide et complet de mon GSM (Samsung S20) jusqu’à 5 fois avec l’autonomie de cette Power Bank. Pour 25 Euros en promotion c’est vraiment une bonne affaire, plus qu’à voir sur la durée mais je n’ai déjà aucune crainte quant à la solidité de cet appareil. Il semble en effet très robuste et il ne chauffe absolument pas durant l’utilisation. Le cable USB intégré permet de s’assure de ne pas l’oublier et l’affichage du niveau de charge est pratique et utile. Pas de gadget inutile, bien pensé.

Anker has become a solid name within the electrical products market, their power banks are among the best, i have used this on a few adventures for charging my Gopro and it last ages. It doesn’t have loads of ports but it has what you need, one dedicated usb c output lead ( so built in ), not very long so it’s design to be stuck in a bag with the device needing charged, it does have a usb c port and a usb port, both act as outputs and inputs ( charge device and charge power bank ), it’s not a light power bank but then you wouldn’t expect that given it’s 20,000mah size and that’s plenty charge for alot of devices. It only has 30w charging which covers lower end needs like certain smart phones. It feels really premium and solid in the hand. One of the key features other than the dedicated usb-c charge lead inbuilt is the two charge rates it has, double pressing the power button will make a green dot appear next to the charge remaining number, this is designed for lower power consuming devices to safely charge them at slower rates. I would really recommend this power bank. Well it seems Ankers product and safety testing is very low! Recall on this model, this gives me very little confidence in their products and will actively avoid them as a brand.
