10,000mAh portable battery with retractable cord

I always like spare batteries that come with charging cables. Not because we like "enough things", but because they make life much more convenient, simpler and lighter. No need to rummage through your bag to find cables, no need to remember to bring separate accessories, and no need to worry about forgetting cables when going out. Just one battery – and you're ready to go.

Shorten it and put it inside the battery.

Pull it out at any distance.

The pioneer with cables is RavPower's power bank. After this model, I don't see them making more. Next is Mophie. They chose a more clever way: clip the wires on both sides, keeping the battery body still elegant and beautiful. Mophie persistently pursued this philosophy for many years. Until now, they are still one of the most loyal names when it comes to portable batteries with built-in charging cables. It's not just about features, it's also about taking care of the user experience.

This model of Mophie is very beautiful and neat. Leather surface, beautiful finish...

Another low-cost model with cable also from Mophie.

This line also has 2 USB-C and Lightning cables available. Mophie still makes backup chargers with cables over the years. About four years ago, the trend changed again. The cable begins to "stick out" and turns into a convenient strap. Users can carry the battery around like a small bag. This solution is practical, easy to identify, but sometimes still makes the whole thing a bit rough.

A battery has an attached cable that when not in use becomes Anker's strap. Then in the last year or so, the technology has become more mature. Many companies launch portable batteries with cables that completely retract inside. The cord disappears when not in use, the battery body remains neat even though the capacity is up to 10,000 mAh. That is a significant step forward - both convenient and clean in appearance. However, looking back at the entire journey, I still see a gap. Most products today still have a technical quality: angular, rigid, "you know the technology when you see it". They solve the functional problem, but don't really touch the emotions.

Mazer also makes a 10,000mAh battery with a retractable cable. The cable is thin, soft and up to 80cm long so it is very convenient.

Cable length can be short or long depending on the user pulling it out.

Supports fast charging according to charging standards, including Samsung's own standard.

Anker also has a similar unit in terms of design and configuration.


However, the design of both Anker and Mazer is basic and complete. Other images:
