Who Should Buy This#
The Anker A1637 is ideal for people who hate juggling a wall charger, a cable, and a power bank every time they leave the house. It gives you one grab-and-go charging tool that can top up your phone on the train, recharge itself from the wall at the hotel, and still handle a second device when needed. If that sounds like your daily carry, View on Amazon is the easiest way to see the current listing.
Perfect for:
- Frequent travelers who want a power bank that can recharge itself in a hotel room without needing a separate charger
- Commuters who need reliable phone power and a built-in cable for quick top-ups between stops
- Remote workers who move between home, office, and cafes and want fewer loose charging accessories
- Minimalist packers who prefer one compact charging tool over a pouch full of bricks and cables
Design & Build Quality#
Anker gives this charger a more polished look than the average travel battery pack. The front panel is glossy with a large percentage readout, while the sides are textured for extra grip when you pull it from a bag or wall outlet. The built-in USB-C cable loops cleanly around the body and also works as a carry strap, so it feels intentional rather than tacked on.
The foldable plug is what makes the A1637 stand out. Instead of packing a separate wall charger just to refill the power bank, you flip out the prongs and plug it straight into the outlet. That all-in-one design is genuinely useful for short trips, airport layovers, and everyday desk hopping where convenience matters more than maximum battery capacity.
Key Features#
3-in-1 Charging That Cuts Down Your Kit#
The biggest advantage here is consolidation. You get a 10,000mAh power bank, a wall charger, and a built-in USB-C cable in one device, which means fewer things to forget before leaving home. For anyone who normally carries a charger brick plus a separate battery pack, this feels much cleaner in daily use.
30W Two-Way Fast Charging#
Anker rates the A1637 for 30W charging and 30W recharging, so it is fast enough for modern phones, tablets, handheld gaming gear, and lighter USB-C laptops that accept lower-watt top-ups. Anker says it can charge an iPhone 15 Pro to 50 percent in 25 minutes, which puts it comfortably ahead of older 18W-class travel batteries.
Built-In USB-C Cable With Carry Strap Function#
The built-in 0.82 ft cable is more useful than it sounds. It removes the usual hunt for a loose cable at the bottom of a bag, and it is long enough for natural phone-in-hand charging without turning the product into a cable mess. Because the cable doubles as a strap, it also makes the charger easier to grab quickly from a backpack pocket.
Foldable Plug for Easier Recharging#
The flip-out AC plug turns the A1637 into its own wall charger. That means you can recharge the pack directly from the outlet instead of packing an extra adapter just to refill it overnight. For travel and office use, this is the feature that makes the product feel smarter than a standard 10,000mAh battery.
Digital Battery Display and Dual-Device Charging#
The front display shows the remaining battery percentage, which is more practical than guessing from tiny LED dots when you are about to head out. Anker also supports charging two devices at once, so you can top up your phone and earbuds together without reaching for a second charger.
