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.

This is small and compact. Easily fits into my day pack without taking up much space or adding weight. I bought this as a second battery for when I'm traveling and exploring, and need to rely on having my phone charged up to access maps, directions, reservations, etc. I've only been able to test this a few times with my Google Pixel phone. Starting from 10% phone charge remaining, this battery was able to charge my phone all the way up while the screen was on and playing YouTube videos over WiFi before the battery was fully drained. To be completely fair, the battery was fully spent by the time it got the phone completely charged. With the screen off and the phone doing nothing, I bet this would charge the phone fully at least 1.5 times?

The USB connection broke off after about 5 months. I talked to the support team at anchor and they sent me a new power charger. I received it within 2 days. This company is above and beyond. I will definitely buy again. Thank you Anker.

Super portable, light, and charges my Samsung S22 Ultra at a pretty good rate of charge. With a small battery I didn't expect it to charge all the way up to 100% (as is advertised). In the beginning the battery held a charge longer but now it can only charge my phone up to about 60%. It's enough in an emergency. Wish it held the charge longer like when you first get it. I do love the design though, where you can flip down the USB-C part. The quality seems good and it's super portable and pretty light. I have a light case on my phone and don't have any issues charging it with the case on.

Anker is my go-to brand for these power banks and cables. This one is awesome for two reasons - the size is perfect to stick in a pocket and carry around, and the built-in USB-C connector means no more worrying about cables. It sort of extends the bottom of the phone when it's plugged in which makes it very easy to use the phone while charging it. Of course, since it's small it has limited capacity, but it's enough to pretty much give me one full charge and that's all I really need routinely.

Like the size and that it plugs directly into my phone without a cord. Meets my needs for charging.

The main selling point is the form factor: It sits at the bottom of a phone and roughly fits the device's profile. Everything else about the product is mediocre, and compared to other Amazon products, bad. The price to capacity is low and the plug is a design flaw. I've only experienced two USB-C connector issues in my life, and this is one of them. The way the weight of the product relies on the grip of the device damages the connectors. To USB-C's credit, but not Anker's, the device's port works fine with other USB-C connectors, and the powerbank will connect to another device fine, but after prolonged use with the same device/charger pair I experienced problems with two different devices. It's not that no one should buy this product, but that Anker has better stuff.

I bought this primarily to charge my Nintendo Switch Lite. I can confirm it works well (see photo provided which confirms in the top right hand corner it is charging). At 5,000 mAh vs the Switch Lite's internal 3,570 mAh battery, it more than doubles gaming time when connected (and starting with a full charge). You can also charge the external battery whilst it is connected to the Switch (and it will still charge the Switch at the same time). No issues with battery life yet but only had it a few days. I will update my review if I find any issues with this.
