    Handy backup but not a powerhouse

    Super handy for quick top-ups, especially when I’m out and about. The built-in USB-C connector is long enough to plug in without removing my phone case, and it folds away nicely when not in use. It charges fast and fits in a pocket or bag, though it’s a bit bulky for tight jeans. If you’re expecting full recharges, keep in mind it’s 5000mAh — great for emergencies, not all-day power. I grabbed it on sale, and for the price, it’s totally worth it.

    Anker Power Bank with Built-in Foldable USB-C Review Anker is known for its high-quality charging accessories, and their power bank with a built-in foldable USB-C connector is a game-changer for those who need portable and hassle-free charging. Design & Portability This power bank is compact and lightweight, making it ideal for travel or everyday carry. The built-in foldable USB-C connector eliminates the need to carry extra cables, making it even more convenient. The overall design is sleek and durable, with a premium matte finish that resists fingerprints and scratches. Charging Performance Anker’s power bank delivers fast charging with Power Delivery (PD) support, ensuring your devices charge quickly and efficiently. With a high-capacity battery (typically 10,000mAh or more, depending on the model), it can recharge most smartphones at least 1.5 to 2 times. The built-in USB-C connector is reinforced to prevent wear and tear, and some models even feature an additional USB-A or USB-C port for charging multiple devices simultaneously. Ease of Use The foldable USB-C plug is the standout feature, tucking away neatly when not in use. This prevents damage and enhances portability. The LED battery indicator lets you track the remaining charge, so you’re never caught off guard. Pros & Cons ✅ Pros: Built-in foldable USB-C connector (no extra cables needed) Fast charging with Power Delivery (PD) support Compact and lightweight for easy portability Durable design with a premium finish High capacity (charges most phones 1.5–2 times) Extra ports (on some models) for charging multiple devices ❌ Cons: No built-in Lightning connector (not ideal for Apple users unless they have a USB-C iPhone or adapter) May take longer to recharge itself compared to some larger power banks Slightly more expensive than standard power banks without built-in connectors Final Verdict The Anker Power Bank with Built-in Foldable USB-C is an excellent choice for Android users, USB-C-powered devices, and anyone looking for a clutter-free, cable-free charging experience. With fast charging, a portable design, and solid battery life, it’s a great investment for those on the go. While it may not be ideal for iPhone users without USB-C, it’s a must-have for travelers and commuters looking for a reliable and convenient. Rating: ⭐⭐⭐⭐⭐ (5/5)

    Honestly I just love how compact and pocketable it is while still offering fast charging to phones that support it. The battery is on the smaller side but for the price I think it's worth it.

    This battery is awesome, is small and easy to carry around, just plug in any device with an usb-c port and keep using it while it charges. For example: If you going to disneyland and want to use your phone all day for photos and video, but you also want to use it at genie+ check in, you dont have to juggle with cables, you wont lose balance of your phone, and you dont even feel it in your pocket like much. For it's small price is a great investment. And if you think you just going to use it once in your life, i'll bet you will change your mind the first time yo use it.

    By far one of my best purchases from Best Buy and I have bought a LOT from them. Only charges your phone one full time but with the battery in the iPhone 15 this is really all you need unless you use your phone 24/7 without putting it down. BUT if you play video games on console, it’s a game changer. You could probably charge a PS5 controller 10 times without having to charge the portable charger, granted this is an estimate but i’ve charged mine 3 times with the charger and it hasn’t gone down a single battery light. I usually don’t write long and detailed reviews but if you’re debating on getting this whether it’s for a phone, controller or anything that uses a USB-C, it’s 120% worth it. It is also a fast charger so when it does charge it charges FAST. Very impressed, might buy another one.

    The power charger is so small and compact that i can fit it in my pocket while still atrached to my phone, unlike other chargers, where their big and bulky with wires hanging out;attached to it. This little unit is just a plug in play. Best charger buy of the year IMO.

    This Nano power bank has quickly become the most-used charger in the house, even though there are already several larger power banks lying around. The built-in foldable USB‑C connector makes it incredibly easy to use on the go without needing to carry extra cables, and the compact size means it stays small and concealed in a pocket or bag while still giving roughly one full phone charge. The extra USB‑C port is a nice touch too, since it lets you either charge another device or recharge the power bank itself through either port, which adds flexibility for different setups. The only real downside is the small gap between the connector and the phone when it is plugged in, which raises a bit of concern about long-term stress on the charging port, especially if the phone is bumped while charging. Overall though, for everyday convenience and portability, this has been a very handy little charger and a great quick‑top‑off option when a full-size power bank is overkill.

    This Anker Nano Power Bank is exactly what I want in a portable charger—small, reliable, and thoughtfully designed. The built-in foldable USB-C connector is a game changer, eliminating the need to carry an extra cable, and it folds away cleanly when not in use. Despite its compact size, the 5,000mAh capacity is perfect for a quick top-up, and the 22.5W fast charging is impressively quick. It feels solid and well-made, like all Anker products, and slips easily into a pocket or bag. A great everyday power bank for travel or daily use.

    This power bank is great when you just need to give your phone a boost up abour 40-50%. Don’t expect it to give you 100% of 5000mAh due to energy lost in converting.

    Always wanted to buy this one. When the bb app notified about the price drop alert, i just grabbed it. I believe it comes in white as well but we should not be particular about colour. This tiny powerbank packs 5000mah. Anker made these with lightening port but had to ditch it when the fruit band went type c. Charges one phone once and can be charged simultaneously while charging the phone.

    What an awesome device to carry for extra life on a cell phone! While traveling, this device is light weight, small size, attaches to the phone easily, and recharges rather quickly between 1 to 1.5 hours. My cell phone gets two full charges from it. Pleased with this choice.
