Portable Charger, Nano Power Bank with Built-in USB C Connector, 5,000mAh Portable Charger 22.5W, for iPhone 17/16/15 Series, Samsung S22/23 Series, iPad Pro/Air, AirPods, and More

This is an amazing power bank! Very affordable while coming from a very trustworthy and reliable brand like Anker. It isn’t enough to charge my IPhone 15 from 0-100 but it can charge it about 40-50 which is great for the size. I love having the built in connector so I don’t have to dig for a cable and untangle it. This is. 5/5 power bank great to keep in a purse, bag, or anywhere else you may need emergency charge. I also love its usb c so I can charge anything from my phone to my cordless hot glue gun!

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.

I've used the similar Anker 5,000 mAh power bank (portable battery charger) that has the lightning connector for my iPhone 13, but my newer iPhone 17 has a USB-C port for charging. Therefore I ordered this USB-C power bank. Other than the connector type they seem the same. I like them because the are small and need no cord for attaching to your phone or other device. (They do use a cord when recharging the power bank itself through the port on the side.) The USB-C port on the side can also charge a device through a cord; it is an In/Out C-port. It can therefore charge devices that don't have a C-port as long as your cord has a C-connector on one end and your device's connector type on the other end. At 5,000 mAh this will provide about one full phone charge or top off a few devices. The smaller power capacity allows it to be more compact and lighter. This one charges devices fast and recharges fast, by my standards. Airlines allow power banks of up to 20,000 mAh so this one is well within TSA allowed limits. All power banks must go in carry-on bags, never in checked luggage because of the fire hazard of all lithium-ion batteries. I considered the thin, flat magnetic Anker power bank that sticks to the back of the phone, but decided on this one instead because this one is faster and can also be used to charge my earbuds, Kindle, and Fire tablets. Anker is a brand that is generally trusted for this type of device. A note on the blue colors... My old lightning-connector power bank was a very light aqua-tinted or sky blue, but this one is a truer blue and a little deeper color. Both are pretty colors for my blue iPhones.

Updated : This review is for Anker Portable Charger Model # A1653 Outcome: Good charger but clunky. Perfect for carrying where space is issue. Fast charging test on iPhone 16 - Test1 : 10% to 60% in 35 min ( charger was half down to 2 dots ) Test2 : 20% to 70% in 40min ( charger was half down ) Gets warm not hot but that was expected. I do see charger is slow in charging itself. I felt connection to phone is not snug tight but its ok as i didnot see any issue with charging my iPhone. Does not lay flat as others have complained due to its thickness which is double size of phone so connecters wouldn’t align, turn it other side for charging if your like. if you r carrying in a bag it will not matter. Its a keeper for me like the folding connector its nice.

Great charger. Light weight & not super heavy. Love that the port folds. Takes a while to charge but charged my phone to 100% once and another 30-50% a second time before it fully ran out of battery. It was great to have for traveling.

This product has been excellent in giving my iPad an additional boost of emergency battery life when needed. It has a heavy and durable construction and has light bars to indicate how much battery life is at your disposal. My research indicated that Anker was the one of the better brands and I highly agree. My expectations were met. No charger in this price zone/category will give a full, instant charge to your device but the power extended is more than acceptable for my usage. I paid a bit more than other devices but was well worth the investment. Great value. Glad I didn’t go cheap.

Easy to charge and easy to use. Small enough to be easily portable and doesn’t really get in the way much while using it. That said, I was disappointed at the speed that it charged my phone (which is fine, cause I know it’s just a portable bank…) but I was very disappointed that even with a full charge, the barely charged my phone to 50%. Ankers used to be so great, but these last two I ordered have been extremely underwhelming.

UPDATE: I've changed my review from 2 stars to 4 stars. Anker seems to be a legitimate honest copy -- they contacted me shortly after my review and offered to refund my money back. They seem to care about their customers, which is a rare thing nowadays with most other companies. So A+ on the customer service! It appears the item I received had a faulty battery. Since Anker stands by their product, and communicates back with the buyer and is honest, I wouldn't hesitate to try buying from this company again. It seems I was one of the rare 3 or 4 people out of a thousand to get a faulty battery. I guess it wasn't my day. OLD: I tested the “Anker Nano Power Bank with built in USB-C connector” and the results were not impressive at all. However, it's possible this maybe because I got a bad charger. Here's what my test showed: Using the power bank charged fully to 100%, I plugged the Anker power bank into my phone. My phone has a 5000mah capacity battery – the same amount of power that Anker claims the Nano can provide. The power bank charged exactly 1 hour and 8 minutes before it died at 0%. My phone was at 27% battery life before charging. After charging my phone with the Anker Nano, it was only able to get my phones battery up to 91% from 27%. So, that’s 27% to 91%. That means this Anker Nano power bank only provided 64% of charge... Doing the math, that means that this is either a bad product; there’s been some false claims, or I received a half functioning dud with a bad battery If the Anker Nano I received isn’t a dud, then that means this power bank is only capable of 3200mah and not the 5000mah power Anker claims or advertises. However, I understand most power banks will be about 10 to 15% off from the mah power that manufactures claim. But since the Anker Nano could only provide my 5000mah phone with 64% juice, that equals out to 36% deficiency in it’s mah power claims. That’s pretty high seeming this is suppose to be a well known and trusted top company. So overall, I’m not impressed at all and feel a little cheated after testing it out. There are several other brand options I could've choose from in around the same price range, so I’m not feeling certain I made the right choice and feel pretty dissapointed. PROS: -It’s compact. It looks nice. CONS: -1 hour and 8 minutes charge time before power bank dies. -Provides only 64% juice to a 5000mah phone battery before it dies. -Doing the math, 64% = 3200mah of power, not 5000mah of power as described by Anker’s description. (...however, it is possible mine may be a dud??) Conclusion: I plan to test some more Anker and other branded products in the future, and I will update once my comparison is complete. I am still searching for a lightweight charging option that works with at least 80% efficiency, as most good power banks do.

Batería pequeña, puedes llevarla en el bolsillo y para lo que quería que es para un apuro te carga el móvil perfectamente. Además es bastante rápida la carga y no necesitas cable

Very handy for charging on the go. Fast

Ich habe die Anker Nano Powerbank im November 2025 gekauft und schreibe diese Rezension bewusst erst jetzt, nach gut 6 Monaten intensiver Nutzung. Ich bin der Meinung, dass Rezensionen, die direkt nach dem Auspacken verfasst werden, kaum Aussagekraft haben. Erst der Alltagstest zeigt, was ein Akku wirklich taugt. Hier ist mein ehrliches Fazit nach einem halben Jahr: Das hat mich überzeugt: Der faltbare USB-C-Stecker ist top. Man braucht kein extra Kabel und der Klappmechanismus hält auch nach 6 Monaten noch fest und leiert nicht aus. Die Powerbank ist extrem klein und leicht. Sie verschwindet problemlos in der Hosentasche oder Handtasche und fällt kaum ins Gewicht. Ladegeschwindigkeit: Mit den 22.5W lädt sie mein Smartphone (und sogar das iPad) angenehm flott auf. Für den schnellen Energieschub zwischendurch ideal. Das sollte man vor dem Kauf wissen: Die Kapazität (5000mAh): Man muss sich bewusst sein, was 5000mAh bedeuten. Durch den natürlichen Energieverlust beim Laden reicht eine Ladung im Alltag aus, um ein modernes Smartphone 1-mal vollzuladen. Als "Lebensretter" für den Notfall perfekt, aber für ein langes Wochenende ohne Steckdose ist sie zu klein. Passform mit Hülle: Wenn man eine sehr dicke oder extrem robuste Schutzhülle (z. B. Outdoor-Cases) am Handy hat, kann es sein, dass der Stecker nicht tief genug reingeht. Bei normalen, dünneren Hüllen klappt es aber problemlos. Fazit nach 6 Monaten: Die Powerbank hält qualitativ, was Anker verspricht. Die Leistung hat nach dem halben Jahr nicht nachgelassen. Wer eine ultrakompakte Notfall-Powerbank ohne Kabelsalat sucht, macht hier absolut nichts falsch.

batterie de petit format, tres pratique et utile pour dépannage quand la batterie du téléphone et presque vide, permet de récupérer pas mal de charge et de tenir plus longtemps.

Parece que foi feito pra mim, era exatamente o que eu precisava! Um powerbank pequeno o suficiente pra caber tranquilamente no bolso da calça e com carga rápida (tanto fornecendo pro celular quanto carregando na tomada). E ainda de quebra nem precisa de cabo, que o conector já vem embutido. Simplesmente maravilhoso!
