With the addition of new BC 1.2 (USB-IF Battery Charging Standard) compatible charging hubs to our product line we wanted to shed some light on a bug we have discovered for Mac users. When using any of the following products an OS X pop-up error message may occur that claims the users iPad is not charging through the hub:
When checking charging status on the iPad itself, it shows that it is indeed charging and can also be confirmed in iTunes. To be completely sure, we test charging rates using a multimeter and confirmed the iPad was charging at the standard 1.5 amp BC 1.2 CDP (Charging Downstream Port) charge rate.
While this error message can be a nuisance, fortunately there is no cause for alarm as the iPad will be charging properly. For users who wish to disable this error message please see the steps below:
To turn off iPad notifications:
Open the Terminal application (found in the Utilities folder inside the Applications folder), then type the following:
Around the office, we’re constantly needing to connect and charge new devices. It’s always a struggle to find a power outlet with enough open spots, and getting many larger plugs to fit, and of course the battle in the dark to actually find an outlet while you’re crawling on the floor under your desk. Plugable’s new desk clamping surge protector helps avoid all of these frustrations thanks to the unique desk clamping design, the 2 oversized “wall-wart” capable outlets, and the 2-port 10.5W (2.1A shared) USB charger built in to eliminate the need for separate USB chargers.
No longer will you need to climb under your desk, searching in the dark to find an open outlet. Instead, just plug it in at arms height!
With up to 2100 joule protection, the PS6-USB2DC offers better surge suppression than many other bargain surge protectors. Joules are a measure of how large a surge is, so a higher joule rating means a protector is able to suppress a larger surge — so the higher the joule rating, the better protection a suppressor offers.
Battery charging over USB has become a standard practice but the actual charging behavior of different devices is often unpredictable and sometimes disappointing. The devices themselves decide how much current to draw and manufacturers haven’t settled on a single standard. We’ve been working to test our products with as many different devices as possible and publish the results so it’s easy to determine the charging behavior to expect from your device on each of our USB products. These are the results for the devices we’ve tested on this device so far.
The "MAX of mA with Host On" is a bit confusing at first glance. The easiest way to understand this is that these values are the maximum reported charging rate (mA) when connected to a computer (host) that is powered on. The "Max of mA with Host Off" is simply the opposite, it is the charging rate (mA) when there is no connected computer (host) or if the computer is turned off.
Some entries in the charging sheet contain blank spaces for the syncing capabilities, that is because we have not had a chance to test that device yet for syncing.
Note that some devices, may charge only at slow "trickle charge" rates, and not indicate they are charging. These are shown as a 0 charge rate.
Still don't see your device? We'd love to hear your experience. Enter your charging results into our charging form and we'll include it in our results data.
Not satisfied with how your devices charge?
Take a look at the USB-MC1 charging adapter. This charging adapter let's you turn any USB port on a powered USB hub or computer into a 1A charging port. The only limitations is that the AC adapter of the powered USB hub needs to be rated for at least 1A for each USB charging adapter. For instance, you won't be able to turn your 10 Port USB 2.0 Hub into a 10 port charging station as the USB hub comes with a 2.5A AC adapter. This means that you can charge at most 2 devices using the USB Charging Adapters, because each adapter will consume 1A leaving .5A for any other devices on the hub.
Let us know if you have any questions at all about our new product. And thanks for going out of your way for Plugable products!
Plugable 6 Outlet Power Surge Protector Clamping Desk Mountable with Built-In 10.5W 2-Port USB Charger for Android, ...
Plugable Technologies is excited to announce two new small, portable, bus-powered USB 3.0 hubs. They provide extra expansion, save wear and tear on your tablet or laptop, are easy to throw in a bag, and are plug and play compatible with Windows, Chromebook, Mac 10.9, and Linux 3.9+ systems.
Both hubs have been designed to fit easily in your bag for travel, with no removable cable to lose. A bulky external power adapter isn’t needed for either hub, as they are solely bus powered from the host computer’s USB port. Both hubs feature the VIA VL812 B2 chipset with the very latest 9091 firmware for maximum compatibility with almost all USB 3.0 equipped computers on the market. They’re also fully backwards compatible with USB 2.0/1.1 devices and hosts. With USB 3.0 SuperSpeed, data transfer rates up to 5Gbps are possible allowing data to move quickly between devices. These hubs are ideal for connecting peripheral items such as flash drives, USB video adapters, keyboards, mice, etc.
The model with Ethernet, in particular, has been engineered down to be the smallest, most portable option available on the market.
Either hub is a must have for any frequent traveler that needs more USB 3.0 ports on the go, but the USB3-HUB3ME is especially useful for computers like the Microsoft Surface Pro or Apple MacBook Air as they are lacking a built-in Ethernet port. Having a wired network adapter can be a life-saver in conference rooms and hotels with marginal WiFi coverage. Being able to use a wired connection instead of a weak wireless connection in these scenarios can drastically improve speeds.
Don’t put up with with several USB devices fighting for the few open ports on your computer. Extend the life of your ports with a USB hub like these.
