A propulsion battery may offer a separate outlet for personal electronics, but its main motor rating does not describe what that outlet can supply. Before treating a SUP power pack as a phone charger or an accessory power source, check the documented auxiliary output, the approved connection and the device’s requirements together.
Separate stored energy from the outlet rating
The current Bixpy PP-384 manufacturer page lists auxiliary 5V and 12V output options, a maximum-current figure of 2.0 A, and separately sold connectors. These are specifications of a named power pack. Its stored-energy figure in watt-hours is a different quantity from the voltage or current available at an auxiliary outlet.
A larger energy figure does not by itself demonstrate that an outlet supports a particular phone’s charging mode, a higher-powered accessory or several devices together. Ask how the stated current limit applies to the intended configuration. Do not assume a USB connector means a specific fast-charging protocol is supported when that protocol is not documented.
Read the accessory’s own limits as well
Bixpy’s separately named 5V USB cable for PP-333/378 batteries describes charging phones, tablets and cameras, while listing a 1 A maximum output. It also says the USB end is not waterproof. Those statements belong to that accessory and its named battery context; they do not establish compatibility with PP-384 or transfer the battery page’s higher figure to this cable.
The comparison illustrates two checks: an accessory can have its own output limit, and a battery’s environmental claim does not automatically cover the connected electronics. Get the maker to identify the approved accessory for the actual battery revision. This guide does not recommend adapters, exposed-terminal connections or improvised wiring.
Make a device-specific power request
Record the phone or accessory model and its documented input requirements. Add the battery model and revision, auxiliary outlet specification, proposed manufacturer accessory and the exact supported charging function. If several devices are intended, list them separately and ask whether the maker supports their combined use.
- Which documented voltage and current limits apply to the complete connection?
- Which charging functions are supported for the identified device?
- What environmental restrictions apply to each component and connection?
- Is simultaneous auxiliary-device and motor use documented for this exact system?
Leave an unanswered question open. A promotional photograph of a phone beside a power pack does not establish the connection, charging speed or permitted operating arrangement.
Keep endurance expectations separate
If propulsion and accessories draw from one battery, request the manufacturer’s evidence for the proposed combined load rather than treating a motor-only runtime claim as unchanged. No accessory-runtime deduction, phone-charge count or reserve-distance calculation has been measured by TRIMIX.
The TRIMIX SUP compatibility checklist covers the wider setup. To ask about actual supply and compatibility, include the board, fin-box, motor and adapter models plus the battery and intended device. TRIMIX has no current public SUP-motor listing; an inquiry confirms neither stock nor a supported connection or order.
Evidence and date notes
Evergreen practical guide checked October 29, 2026. Both primary manufacturer pages are undated. Current PP-384 output information and the separately named PP-333/378 accessory are not presented as one verified combination, a new launch or a TRIMIX test.
