FAQ
Charging cart questions, answered directly.
EnTrans (英创思) is a manufacturer of charging carts and cabinets for managed tablet, Chromebook, laptop and VR device fleets, with 6 series and 17 current configurations. The figures below come from our public product and certificate pages and were checked on 6 November 2026. Series-level guidance is not a final specification; configuration and compliance are confirmed during quotation.
What is the total output of a 32-port PD18W charging cart?
32 x 18W = 576W. The EnTrans ET32 lists a maximum output of 576W; ET48 is 864W, ET64 is 1152W and EN60 is 1080W. This figure is the simultaneous total across all bays, not per-port power and not input power.
PD18W or PD60W: which charging cart should I choose?
Start with the device. For fleets of USB-C tablets that accept an 18W profile, ET32, ET48, ET64 and EN60 keep site power demand low. For compatible Chromebooks and laptops that need 45W or 60W, look at the matching EP36-B configuration; its 36 PD bays at 60W give a maximum total of 2160W. Always verify the device's supported PD voltage profiles first.
Can a 2200W AC/PDU cart be compared directly with a 1080W USB-C cart?
No. An AC/PDU cart such as EP30-A or EP45-A lists 2200W as shared AC supply where each device keeps its original adapter. EN60's 1080W is the DC output summed across 60 USB-C PD18W ports. EnTrans states that AC/PDU ratings are not directly equivalent to USB DC output.
What is the difference between charge-only and data-sync versions?
Charge-only versions supply power; data-sync versions add USB 2.0 host-to-device communication for bulk content distribution and usually list a lower output. OM32 is 396W charge / 330W sync, and EC30 - VR is 576W PD / 320W sync. They are separate configurations and the required version must be stated when ordering.
Can a USB-C PD charging cart charge laptops?
It depends on the laptop's accepted PD voltage profile and required power. ET32, ET48, ET64 and EN60 are PD18W tablet carts and EnTrans asks buyers to confirm laptop compatibility with PD18W. Compatible Chromebooks and laptops can use the EP36-B 45W or 60W configurations, or an AC/PDU cart such as EP30-A or EP45-A that retains the original adapter.
How do I verify that a certificate covers the model I am buying?
Request the original certificate and check its validity dates, covered model scope and target market. EnTrans publishes CCC 2025010907786364 (13 Jun 2025 - 10 Dec 2029, covering the ET, OM, EN, EC, EL and EP series listed in the certificate) and EN IEC 62368-1 LGT25B040C02-01 among others. Certification and protection claims vary by model and market and are confirmed during quotation.
