ELECOM has released the DE-C92-5000 series, a 5,000mAh power bank with a retractable USB Type-C cable built into the body, launched in mid-June[1]. The cable can be extended to any length up to about 62cm and stows neatly back into the body when not in use[1]. It supports USB Power Delivery output of up to 20W, and in addition to the integrated cable it has a USB Type-C port and a USB-A port, allowing up to three devices to be charged at the same time[1].
A built-in, retractable cable for easy carrying
The defining feature of the DE-C92-5000 series is the body-integrated retractable USB Type-C cable[1]. The cable length can be adjusted within a range of about 62cm, and when stored, even the connector tucks back into the body, so it does not add bulk inside a bag[1]. The integrated cable can be used not only to power devices but also to recharge the unit itself[1].
Power banks are convenient, but they have long carried a weakness: if you forget the dedicated cable, you cannot charge anything. By building the cable into the body, ELECOM aims to let users carry the unit every day without worrying about forgetting or losing a cable[1]. The connector on the integrated cable features a metal accent for a more refined look[1].
The body measures about 62mm wide, 27mm deep and 80mm tall and weighs around 150g, making it compact enough to fit in the palm of a hand[2]. Two color options are available: black, and a "Shiro-chan" model with a one-point design[1].
20W output, up to three devices at once, and Switch 2 support
For output, the integrated cable and the USB Type-C port deliver up to 20W via USB Power Delivery, while the USB-A port supplies up to 18W[1]. With the integrated cable plus one USB Type-C port and one USB-A port, up to three devices can be charged simultaneously[1]. Note that when multiple ports are used at once, a combined maximum of 15W is distributed among them, so per-port output drops[1].
Beyond smartphones and tablets, the unit can also charge the Nintendo Switch 2, Nintendo Switch and Nintendo Switch Lite[1]. ELECOM notes that depending on the operating mode, charging while playing may not be possible, and that for the Switch 2 and Switch, use together with a dock is not supported[1].
As a reference, the 5,000mAh capacity can charge a 1,800mAh smartphone about 1.6 times and a 3,000mAh smartphone about 0.9 times[1]. It uses a rechargeable lithium-ion battery rated for about 500 charge cycles[1].
A 1%-step battery display and a full set of charging features
The unit carries an LED panel that shows the remaining battery level in 1% increments[1]. This is handy when topping up the unit in advance and you want to track the level precisely[1].
The charging features are well rounded. It supports "charge-together" operation, which charges both a smartphone and the unit while the recharging cable is connected, as well as pass-through charging, which feeds power directly from the charger to the connected device without going through the battery, helping to limit battery wear[1]. The USB-A port also offers a low-current mode that charges small devices such as Bluetooth earbuds at an optimal current, plus an "auto" charging mode that identifies the connected device and adjusts the charge accordingly[1]. Charging the unit alone takes about 1 hour 30 minutes as a guide[2].
Note that an AC charger is not included, so one must be prepared separately[1]. ELECOM recommends an AC charger of 20W or more[1].
Safety design, eco considerations, and airline carry-on
For safety, the unit includes Thermal Protection that monitors and controls the temperature of the body, along with multi-layered protection that automatically stops operation when an abnormality is detected[1]. It clears the technical standards of Japan's Electrical Appliances and Materials Safety Act (PSE), and the built-in battery is designed to the JIS C 62133-2:2020 and JIS C 8715-2:2024 standards[1].
Because the battery capacity is at or below 160Wh (43,243mAh), the unit can be carried onto aircraft[1]. Easy portability for business trips and travel is an important point for a power bank, though ELECOM notes that exceptions may apply depending on each airline's rules[1].
In addition, the product is certified under ELECOM's in-house "THINK ECOLOGY" environmental standard, reflecting considerations such as the use of recycled materials and reduced packaging plastic[1].
Lineup and pricing
The lineup consists of two models: the black "DE-C92-5000BK" and the "Shiro-chan" model "DE-C92-5000WF," both at open pricing[1]. They are sold through retailers such as Biccamera.com and Yodobashi.com[1].
Power banks with built-in cables are now offered by many makers, but combining a retractable cable and two ports with a compact 5,000mAh capacity—prioritizing airline carry-on compatibility and everyday portability—appears to be this product's positioning.
Summary
The DE-C92-5000 series is a 5,000mAh power bank with a built-in retractable USB Type-C cable. It supports USB Power Delivery output of up to 20W and can charge up to three devices at once via the integrated cable and two ports, including the Nintendo Switch 2. With a 1%-step battery display, pass-through charging and airline carry-on compatibility, it is a practical unit built for easy daily carrying, and a strong candidate for anyone who wants to drop the hassle of carrying a separate cable.
