The Anker Nano Power Bank 45W is Anker’s model A1638, sold as the Anker Nano Power Bank (10K, 45W, Built-In Retractable USB-C Cable). It packs a 10,000mAh battery, a USB-C cable that pulls out of the body and winds back in, a second USB-C port, a USB-A port and a small screen that shows the charge level and which way power is flowing. This listing is the Aurora White colour. The point of the design is simple: you never need to remember a separate cable for your phone.

Anker Nano Power Bank 45W: The Retractable Cable
The cable is the reason to choose the Anker Nano Power Bank 45W over an ordinary 10,000mAh pack. Anker lists it as a 2.3 ft (about 70 cm) USB-C cable built into the body. You pull it out to the length you need, and it retracts when you are done, so there is nothing loose in your bag and nothing to forget in a hotel room.
Anker states the cable was tested to withstand 20,000 bends and 20,000 pulls. That is a lab figure, not a promise that it can never fail, but it shows the cable was designed for daily use rather than as an occasional extra. A cable of 70 cm is long enough to keep using a phone while it charges from a pack sitting on a table or in a pocket.
Because the cable on the Anker Nano Power Bank 45W is USB-C at the end, it suits iPhone 15, 16 and 17, recent Samsung Galaxy and Pixel phones, iPads with USB-C and most wireless earbud cases. Older iPhones with a Lightning port need a separate adapter or cable, which Anker does not include.
How Much Power Each Output Gives
The Anker Nano Power Bank 45W reaches 45W only from the USB-C cable or the USB-C port, one device at a time. Anker is specific about the device limits: up to 45W for Samsung phones that support it, and up to 40W for the iPhone 17 series. The USB-A port gives up to 22.5W, which suits older phones, earbuds and smart watches.
When you charge more than one device, the total drops. Anker lists 22.5W combined when the cable and the USB-C port are used together, split as 15W to the cable and 7.5W to the port. With all three outputs in use, the total is still 22.5W, at 7.5W each. For the fastest charge on one phone, unplug everything else.
The Anker Nano Power Bank 45W also supports pass-through charging: it can charge your phone while it is itself plugged into the wall. That is handy overnight in a hotel with one socket.
Recharging the Pack and the Smart Display
The Anker Nano Power Bank 45W recharges at up to 30W through USB-C. Anker recommends a 30W or higher USB Power Delivery adapter for the best recharge speed. A slower phone charger will still work, only more slowly. Anker does not publish an exact full-recharge time for this model, so we do not quote one.
The display is light-sensitive, so it dims in a dark room and brightens outdoors. It shows the remaining battery and real-time power flow, which tells you whether the pack is charging, discharging or doing both. Anker also lists its ActiveShield 3.0 temperature monitoring, which checks the temperature during charging and adjusts power.
Aurora White: Size and Everyday Carry
Anker gives the size as 3.21 x 1.99 x 1.42 inches, about 81.5 x 50.5 x 36 mm, and the weight as 0.51 lb, about 231 g. Anker describes it as about as compact as two AirPods cases and close to the weight of an iPhone 17 Pro Max. The Anker Nano Power Bank 45W fits a jacket pocket or the front pocket of a backpack, but it is thicker than a slim magnetic pack.
On the Anker Nano Power Bank 45W, Aurora White is the lightest of the four colours Anker shows, next to Teal Oasis, Pink Aura and Misty Blue. White keeps the look clean next to a white or silver phone, but it also shows marks from bags and pockets sooner than a darker colour would. A slightly damp cloth cleans the shell; keep liquids away from the ports and the cable opening.
Who This Is Not For
Not for charging a laptop at full speed. The Anker Nano Power Bank 45W tops out at 45W from one USB-C output, and 10,000mAh is a phone-sized battery. It can top up a small USB-C laptop, but anyone who works away from a socket for hours needs a larger laptop power bank.
Not for anyone who needs to charge two phones quickly at the same time. With two or three outputs in use, the total output falls to 22.5W.
Not for Lightning-only iPhones without an adapter, and not the right pick if you want MagSafe-style magnetic charging, which this model does not have.
