A compact charger with built-in cables looks like an easy answer. For a retailer or distributor, the harder question is what happens when customers plug in all those devices together.
The label “45W” is a useful starting point, but it does not describe every charging combination. Before adding a multiport charger to your range, ask for the information that helps your team explain the experience accurately.
Check the output for each connection scenario
Request a clear output table for one device, two devices and all supported connections in use. Confirm which cable or port receives priority and how the available power is shared. A maximum rating should never be presented as a promise that every connected device will receive that wattage at once.
USB Power Delivery is designed to let connected devices request the power they need; the final charging behavior also depends on the charger, cable and device. USB-IF’s documentation includes a separate shared-capacity interoperability test for USB-C chargers, which is a useful reminder that multiport behavior deserves its own check.
Test the mix your customers actually carry
Build a simple test set: a phone with a low battery, a tablet, earbuds and a second phone. Record what happens when each additional device is connected. Does charging continue as expected? Do customers understand which port to use for a larger device? Include the regional plug version and the devices common in your market.
Evaluate the cable experience, not only the power rating
For a travel charger with retractable cables, test whether the cables reach a bedside table or shared desk comfortably, retract smoothly and remain easy to put away. Inspect the cable ends and ask for the supplier's durability and service information. These details shape the daily experience and the questions your sales team will receive.
Precisely Introduces the Product
Mietubl lists the MTB-CS15E with built-in 1.2 m USB-C and Lightning retractable cables, two additional USB-C ports, support for up to four connected devices and up to 45W output.
The wall charger comes with 4 output,2 USB-C out put which both support Max 15W(5V/3A、9V/3A、12V/3A、15V/3A、20V/2.25A) output , 1 built-in USB-C cable which supports Max 15W(5V/3A、9V/3A、12V/3A、15V/3A、20V/2.25A) output and 1 built-in lightning cable supports 5V/3A、9V/3A、12V/2.25A、15V/1.8A、20V/1.35 output.
The retractable data cable design and supports simultaneous charging from all four ports. makes it ideal for travelers who need to charge multiple devices simultaneously.
For buyers, a strong product story begins with a real situation: fewer loose cables in a travel bag and one tidy place to charge at night. A verified output table and hands-on multi-device test then give that story the technical proof it needs.
