The Bretford PowerSync D20 is a product which offers a basic sub-set of the features from a PowerPad15S so the two products are in some way comparable.

The major differences and things for/against each product are outlined below.

There is also a downloadable PDF comparison which gives more detail along with a simple side by side feature comparison.

—————

The Bretford D20 offers basic features at a premium price whereas the Cambrionix PowerPad15S does everything that the Bretford D20 does but in a more compact package, with less cost per port, with more safety certification plus the addition of port monitoring and control via either an application programming interface or GUI app.

—————

The Bretford D20 is aimed squarely at use within the classroom where having the power supply inside the box could mean one less thing to lose. The PowerPad15S is a more professional device offering features far in excess of the D20 for professional use.

—————

The Bretford D20 is certified for use in the USA (with its UL Listing and FCC Part 15 Certification) whereas the Cambrionix PowerPad15S is certified for use in many more countries across the globe including Europe.

—————

The D20 includes a set of cables for connection to iOS devices (you can choose either Lightning or the older 30way connector) whereas the PowerPad15S works will ALL USB chargeable devices, not just iOS devices. Cambrionix also believes that an extra set of cables is unnecessary cost which is included in the D20 price. We estimate the additional cost for the extra cables should be in the region of around £10 (~$13) per cable for a decent MFi Certified example.

—————

The ‘per-port’ cost of the Cambrionix PowerPad15S is less than half of the Bretford D20 even taking into account the D20 being shipped with cables. The per-port cost is an important cost comparison between products as many of them have different port numbers. To put this into perspective, if you were to invest the same amount of money as the D20 costs into PowerPad15S units, you would have over twice the amount of charge and sync ports. If you connect the PowerPad15S units to separate USB host controller ports on your host computer you will provision/update/restore more mobile devices in less time than the D20.

Both products work seamlessly with Apple Configurator.

—————

The Bretford D20 will not charge iOS devices during a sync (data transfer) process as there is no hardware support for CDP (Charging Downstream Port). This will mean than during an iOS update/restore/provisioning your iOS battery level will deplete. This is not ideal because sync tasks using a product such as Apple Configurator can take a long time to complete when so many iOS devices are connected. The Cambrionix PowerPad15S fully supports CDP as part of its firmware controlled suite of charging profiles. This means that whenever an iOS device (or any other device which supports CDP etc) is connected to the PowerPad15S it will be charging at the maximum rate that the manufacturer allows.

This brief review has been written by Cambrionix after our internal lab testing of the Bretford D20. We have tried to be as unbiassed as possible.

If you would like to verify any of the details within this review yourself you can find details of the Bretford D20 and Cambrionix PowerPad15S at the following links:

If sync speed is a priority to you, and you would like to perform iOS provisioning/updates/restores 10x faster than both the Bretford D20 or the PowerPad15S, the Cambrionix ThunderSync16 is a better choice. The link below takes you to the ThunderSync16 product page. Again, the ThunderSync16 offers all of the PowerPad15S features and adds an increased iOS charging level (2.4Amp/12W) and dual LEDs per port. ThunderSync16 is 10x faster than the D20 and also smaller and lower cost. ThunderSync16 uses Thunderbolt Technology to achieve incredibly fast sync speeds.
