Specs: Capacity: 5,000mAh USB-C Input: 5V⎓3A / 9V⎓2A (18W Max) USB-C Output: 5V⎓3A / 9V⎓2.22A / 10V⎓2.25A (22.5W Max) Total Output: 18W Max Weight: 3.5 oz (100 g)
Why is my power bank providing fewer charges than expected?
The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker Nano Power Bank offers an estimated 2,750mAh to 3,500mAh to power devices.
How can I estimate the number of charges for my device?
To estimate the number of charges: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity. For example, a 5,000mAh power bank gives an iPhone 15 (3,877mAh) about 0.8 charges, and an iPhone 15 Pro Max (4,852mAh) about 0.64 charges.
How can I charge an iPhone 14 Pro Max with this power bank?
To charge iPhones prior to the iPhone 15 series, an additional USB-C to Lightning cable is required (not included).
Is it normal for the power bank to get slightly warm during use?
Yes, it is normal. The product meets safety standards with a maximum temperature rise of 118°F (48°C).

Very convenient and portable
Small, lightweight, and easy to use. The built-in connector is very convenient, and it charges my phone reliably. Great quality as expected from Anker. Perfect for everyday use.

Pocket-sized battery, great to keep in a pocket or bag for emergencies
I see a bunch of one-star reviews, mostly from people who seem confused about battery capacity, energy, power, voltage, current, etc.People complain that this little pocket-size battery won’t fully charge their iPad. That’s like buying a little one-gallon gasoline can for emergencies, and then complaining that it when you poured it into your truck’s empty gasoline tank it didn’t fill the tank all the way to the top.The cell inside the Anker Nano Power Bank is advertised as having a capacity of 5000 mAh. That means the cell can (for example) supply 5 A for one hour, or 2.5 A for two hours, or 1 A for five hours. Battery engineers like talking about mAh because it is useful for their circuit designs, but for the rest of us it’s not very useful, because knowing the energy in 5000 mAh depends on knowing what voltage we are talking about. For end users, it is more useful to compare batteries based on the energy they store rather than the amount of current they use to deliver that energy. So that means talking about watt-hours (Wh) instead of mAh.For this battery the cell voltage is about 3.6 V, so 5000 mAh gives you 18 Wh.But phones aren’t designed to take power at 3.6 V. Phones require 5 V (or higher). Voltage conversion circuitry is not perfectly efficient. The text on the battery itself claims, “2600 mAh @ 5V x 2.4 A,” which means it can deliver 2.6 x 5 = 13 Wh of energy. This means that the voltage conversion circuitry inside the Anker Nano is about 72% efficient, so the 18 Wh at 3.6 V becomes 13 Wh at 5V (28% of the energy is wasted as heat). In practice, measuring a couple of Anker Nano Power Banks using a USB energy meter, I found they actually deliver 12 Wh (2.4 A @ 5V for one hour). 12 Wh is close to the 13 Wh that Anker claims, but not quite.My iPhone 15 Pro Max has a battery capacity of 17.32 Wh. Charging a battery is also not perfectly efficient — charging makes your phone get warm, and that heat is more wasted energy. If we assume that battery charging is also 72% efficient, then the 12 Wh from the Anker Nano becomes 8.64 Wh in the phone battery, or about half of the my iPhone 15 Pro Max battery capacity. In my experience the Anker Nano does indeed charge my phone from empty to around 50%.Because the Anker Nano supports USB C voltage negotiation, phones that support higher voltages can request up to 10V, allowing the Anker Nano supply up to 22 W for faster charging than a normal USB 5 V supply.The Anker Nano Power Bank is great for unplanned situations where you unexpectedly find your phone battery is drained. The Anker Nano is a small battery that easily fits in a pocket or a bag, and you don’t need to remember to carry a cable with it, because the built-in USB C plug connects directly to the device being charged. If you prefer to use a cable, it also has a USB C socket for that.Last year at the end of a day of skiing I found myself trapped for two hours in a broken-down gondola with four other people. All of their phone batteries were drained, and they were concerned about how they could tell their friends where they were. I pulled the little Anker Nano out of my pocket and passed it around. Within a few minutes everyone had charged their phone 10-15%, enough to call their friends and let them know what was happening.

Charging speed and battery life
I’ve been using this portable charger for a little while now, and it has become something I always keep with me. It’s lightweight, compact, and fits easily in my bag without taking up much space. The charging speed is impressive — it boosts my phone quickly, even when I’m on the go.The battery capacity is also solid. I can get multiple charges out of it before needing to plug it back in, which is great for long days or travel. The display/indicator makes it easy to see how much power is left.Overall, it’s a reliable and convenient charger that does exactly what you need it to. Definitely worth the purchase if you want something dependable for everyday use or trips.

Very good phone charger, but stand-by power is limited on newer model
This Anker Nano Power Bank has been excellent for fast-charging my smartphone, much faster than any of my other phone chargers, and of course, very handy since a cable is not needed. My only disappointment has been with an “off-label” function that has changed.I bought my first Anker Power Bank in December 2023 after reading a review that its functionality included a 25-30 minute stand-by period, much longer than cheaper power banks that usually had a 30-second stand-by period. In other words, if the power bank was being used to power something intermittently – like a card shuffler being used every 10-15 minutes – it would remain active and the On button would not need to be pressed each time before use. Unfortunately, I lost my first power bank on vacation and purchased a replacement in June 2025. The replacement was still an excellent phone charger, but it had lost the ability to remain on stand-by for 25+ minutes, and only offered a brief stand-by period of 20-30 seconds, the same as the cheaper power banks. I contacted Anker and they said that there was probably a firmware or hardware change that had been made between December 2023 and June 2025, in the interest of minimizing even any tiny extra drain during stand-by. So … still a great phone charger, but without the extra functionality that was useful for certain other USB-C powered things.

Puts the “power!” in power bank
This power bank much like the wall chargers can conceal its c-plug in order to prevent it from being damaged. Its a slow charge but an even faster charger and last for a long time. It took my phone from 15% to 30% in a jiffy. Its also worth the value for your money. Its sleek slim design is honestly unique to this brand alone. This power bank puts the power first. It is also travel friendly for those who take the plane a lot. All in all its worth it I give it a 10/10 and highly recommend.

Handy but fragile
Charges fast and well. Can’t say it fills up my Pixel 8 Pro more than 50%. Size factor is great, very convenient. However, the little flip out connector is flimsy and fragile. I dropped the phone once and the connector broke and is now dangling.

Good for on the go
Nice, small, portable charger. I use it for a Samsung Galaxy FE25 and it works well. Good for when you need a quick charge.

Compré este cargador portátil de Anker buscando algo extremadamente ligero y fácil de llevar, y este modelo de 5000 mAh superó mis expectativas en portabilidad.✅ Lo que me encantaUltra-Portátil: La característica que más me gustó es que prácticamente no pesa. Es ideal para meter en el bolsillo o un bolso pequeño sin que se sienta voluminoso.Diseño Perfecto: El diseño es compacto y ergonómico. Se adapta muy bien al teléfono mientras está cargando, lo que me permite seguir usando el móvil cómodamente.Carga Fiable: Cumple su función principal: carga bien y de forma consistente, dándome la energía extra que necesito para terminar el día.⚠️ El único “pero”Mi única crítica tiene que ver con la relación capacidad-precio. Siento que, por lo que cuesta, Anker podría ofrecer un poco más de capacidad (quizás 7000 a 10000 mAh) para hacerlo una opción perfecta.💡 ConclusiónSi tu prioridad es la portabilidad absoluta y la confianza de una marca como Anker, este Power Bank es una compra excelente. Si necesitas cargar tu teléfono dos o tres veces al día, quizás debas buscar un modelo de mayor capacidad, pero si solo buscas una carga de emergencia fiable, ¡es perfecto!

The Anker Nano Power Bank is a compact and reliable charging solution for on-the-go use. Despite its small size, it delivers fast and efficient charging, thanks to Anker’s PowerIQ technology. Its lightweight design makes it easy to slip into a pocket or bag, perfect for travel or daily carry. While it may not have the highest capacity for multiple full-device charges, it excels as a quick top-up solution for smartphones and small devices. Overall, it’s a sleek, dependable power bank that balances portability and performance.

I use 2 of these. Haven’t needed to use them both on the same day, so I’m assuming the power is enough to get you through 1 day.It’s small and portable. No need for a cable.It’s my favorite power bank and I always have 1 on me.
