Anker A1637 Nano 3-in-1 Portable Charger, 10,000mAh 30W

A built-in USB-C cable and foldable wall plug bring charging essentials together, so there’s less to pack for a trip or a day out. The Anker Nano A1637 also works as a 10,000mAh power bank. Its 30W two-way fast charging supports charging both the bank and connected devices.

Why it makes sense

Instead of carrying a wall charger, a separate cable, and a portable battery, this 3-in-1 design combines those functions in one device. Plug it in to charge, or use it as a power bank when an outlet isn’t handy. The integrated USB-C cable is ready to connect to compatible devices, while a separate USB-C port gives you another connection point.

That combination is useful when packing light matters: keep it in a travel bag for a short trip, or bring it along for a full day away from an outlet. Buyers frequently highlight the compact carry format, built-in cable and plug, and charging speed. Feedback about durability varies, so those impressions are best viewed as individual experiences rather than a guarantee.

The essentials

The 10,000mAh capacity gives you portable power, and the 30W output supports fast charging. Anker states that an iPhone 15 Pro can charge from 0% to 50% in 25 minutes, actual charging can vary with the device and conditions. The unit can charge two devices at once, making it handy when you need to top up a phone and another compatible device together.

It is designed for smartphones and is listed for the iPhone 15, 16, and 17 series. For iPhones before the 15 series, Anker says to use an additional USB-C to Lightning cable. The built-in cable is USB-C, so the connection you need depends on your device. A foldable wall plug makes the charger convenient for outlet use, while the battery supports charging away from a wall. Anker lists an approximate two-hour recharge time at 30W.

How to use it

For a quick top-up at a wall outlet, unfold the plug and connect the charger. When you’re heading out, take it along as a power bank and use the built-in USB-C cable or USB-C port to connect a compatible device. If two devices need power at once, connect them to the two available charging connections. This integrated approach suits travelers who prefer one compact charging setup over packing a separate wall adapter, cable, and battery.

Before you decide

Can it charge two devices at the same time? Yes. It has two charging connections and is designed to charge two devices simultaneously.

Can it charge an iPhone before the 15 series? Yes, with an additional USB-C to Lightning cable for those models.

Does it work as a wall charger as well as a power bank? Yes. Its foldable wall plug supports outlet use, and its 10,000mAh battery provides portable charging when you’re away from an outlet.

Should you buy it?

Choose the Anker Nano A1637 if you want a travel charger that combines a wall plug, built-in USB-C cable, and portable battery, rather than assembling those pieces separately. The 30W charging and ability to power two devices at once make it a practical fit for people carrying compatible phones and looking for a simpler everyday or travel charging kit.
