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 2.5 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, allowing it to be recharged while it charges devices likesmartphones simultaneously.
Can I bring it on a plane?
Yes, in general, power banks with a battery capacity under 27,027 mAh (100 watt-hours) can be legally and safely carried on planes.
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).
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.

Compact, fast and genuinely convenient to use
Picked this up as an everyday power bank and it’s honestly one of the better ones I’ve used. The size is spot on, small enough to carry around easily but still packs enough power to charge a phone a couple of times, which makes it ideal for work or traveling. A 10,000mAh capacity is usually good for around 2 full charges depending on the phone, and that’s pretty much what I’ve found in real useThe built-in USB-C cable is probably the best feature. It sounds simple, but not having to carry a separate cable makes a big difference day to day. It also feels solid and well made, designed to handle a lot of use without wearing out quicklyCharging speed is genuinely good as well. The 30W output means it charges phones quickly, and it can push a decent amount of power compared to cheaper banks. It’s fast enough that you actually notice it topping your phone up quickly rather than just slowly maintaining itBuild quality is what you’d expect from Anker, feels reliable and well put together. It’s not super light, but that’s the trade-off for having a decent battery inside. Still perfectly portable and easy to throw in a bag or even a large pocket.If I had to be picky, it’s not going to power laptops properly and it’s more focused on phones and smaller devices. Also, like most 10K banks, you’ll still need to recharge it regularly if you’re using it heavily.Overall, really solid bit of kit. Fast, convenient and good value for money. Perfect for everyday use where you just want something reliable that works without hassle. Would definitely recommend.

Good quality as expected from this manufacturer
Compact, & a nice weight so easily transported, it’s a good quality charger. Long battery life, fully compatible with my apple ipad, feels very durable, comfortable to handle with nice rounded edges.Shows a digital display of battery life when on charge, & also when in use. Easy to use and a good design. Recommended

Great power bank with built-in cable
Absolutely love this power bank. It shows the battery percentage, which makes it easy to keep track and top up when needed. It’s lightweight and really convenient to carry around.The built-in USB-C cable is a big plus, and you can still use the USB port as well. It’s handy being able to charge multiple devices at once, although it does slow down slightly when doing this.I use it with an iPhone 17 Pro and get around two full charges from it. I liked it that much I bought another for myself and a couple for family members

Good piece of kit!
I really like this power bank. It stores a good amount of power: I can charge my phone fully twice with this and it feels sturdy, which I appreciate when on the move.In terms of portability, it is a bit on the heavy and chunky side and might not be the right fir some someone looking for something sleek and lightweight.It fits into small pockets in a bag or bagpack and does not get hot when charging or being charged.

Thick but excellent quality
At 1 inch thick, it’s quite thick. And to be honest, it can’t fit in small pockets or pockets with other stuff in. What it *can* do really easily is go in a large coat pocket or rucksack without adding much weight.The exterior feels nice. The built-in cable clicks into its storage slot solidly. There’s an extra bit that helps it stay clicked in, so using the storage slot won’t degrade your connector. It’s strong enough that you could carry it around by the cable loop without worry. I probably wouldn’t sling it to a bag by the loop though, just in case it took a big jolt and came open.It holds charge while on standby really well. I charged it to 80% 7 days ago now, and it’s still at 80%.At 10,000 mAh raw capacity and 6,000 mAh effective capacity, it’ll hold roughly 1.5 full charges of the average phone.At 30W max output, it’ll charge your phone at a good pace, and keep charging up even when you’re doing heavier stuff like Google Maps. The power bank supports a wide range of Voltage/Amperage combos, so you should reach the full 30W on a lot of devices.At 20W input, it charges quickly for a 10,000 mAh power bank. I bought an Anker Zolo 50W charger to charge the power bank and the second USB C port on that delivers 9V/2.22A, which is one way of ensuring you get the full 20W. Many other chargers will also get you the full speed, of course, I just like that one.You should buy this power bank if:* You need a power bank for a rucksack or a big coat pocket.* You want at least a full charge of your phone ready.* You want a built-in cable.

Absolutely perfect – Compact and powerful
I’ve been using the 10,000 mAh power bank for 4 months now and do not have a single fault with it. It can charge my 6 year old phone multiple times over and has been a lifesaver on long days out/working. Originally, I was sceptical of the built in cable being a weak point, but now I’m 100% sold on it, it’s so much easier than having to carry around an extra cable. The USB A port is also great for using with a micro USB cable for a couple of older devices I own. The battery display indicator is very helpful, much better than cheaper devices with only a couple of status LEDs. For £15 I really cannot fault it.

Charges sevices quickly
Excellent product – charges devices quickly and holds multiple charges. Is a little heavy but great when travelling

Excellent power bank
Great little power bank. The integral charging cable is a clever idea. It’s compatible with usb-c phones. Charges up quickly and is fast to charge my phone. There is a digital display showing the charge level. It’s sturdy and doesn’t get hot. Anker is a trusted brand and although their products aren’t the cheapest, you can guarantee they perform brilliantly

As expected. Really good, good quality. I have an iphone 15 pro and I can charge it aprox 2.5 times.

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 😉

Uso questo powerbank da circa 4 mesi. Scelto per le dimensioni a saponetta e per la possibilità del cavo integrato. Comprato prima dell’estate, da allora lo porto sempre con me nella mia sling da 2 litri. I 10.000mah sono il giusto compromesso tra capacità energetica, peso e dimensioni soprattutto se viene usato per ricaricare i dispositivi di una sola persona. Ci carico uno smartphone con una batteria da 5000 circa due volte considerando però che non arrivo mai con una batteria mai al di sotto del 30/35%. È possibile caricare contemporaneamente 3 dispositivi e in confezione viene fornito un ulteriore cavo usb-c usb-c, corto ma sempre meglio di niente. Cosa importante è che può essere ricaricato mentre a sua volta carica altri dispositivi.Il display è minimale e mostra solo lo stato di carica delle batterie interne.Le uniche pecche, a mio avviso, sono le plastiche che si graffiano facilmente e la sua ricarica a soli 20W che fa si che una sua carica completa duri circa 2.30h. Per il resto è un ottimo prodotto offerto ad un buon prezzo.
