1.0 out of 5 stars Battery does not power up USB devices standalone, September 19, 2007

This review is from: CyberPower Mobile Battery Powered 4-Port USB Hub (CP-H420MP) (Personal Computers)

The reason I bought this product is so that I could power up USB devices and the hub with the included batteries. Unfortunately, the hub will not power any devices I tried nor operate as a hub without drawing power from a laptop or PC. The manual states that the red LED will extinguish when the batteries have discharged. However, even when I removed the batteries, the red LED remained on. Basically, there does not seem to be any way to determine if the batteries are doing anything. I am still looking for a true battery powered hub.

2.0 out of 5 stars Not Recommended, July 17, 2007

I don't recommend this unit for the following reasons:
1) The precision of the case is quite poor. I was almost unable to open the battery cover. I finally used my Swiss Knife to modify the battery cover to resolve the problem.
2) The battery indicator is only passive (switch on/off indicator only) and cannot tell you if the batteries are in use or not. Even without the batteries, the indicator can be still on. I cannot confidently say that this device does not draw power from my vulnerable VAIO UX280.
3) When using the Sennheiser USB adaptor on this device, the audio quality was significantly degraded. I assume that this device cannot keep data flow fast enough.

3.0 out of 5 stars CyberPowered Confusion, April 23, 2009

First off, I have to admit that I actually like this product a lot - it does work, and it is very convenient to own and use. However, there is no doubt some serious problems that need to be cleared up. This is NOT a portable "stand-a-lone" battery powered USB Hub.

It is a USB Hub with rechargeable batteries that you may "switch on" if your device draws too much current from the hub to operate properly. It will NOT re-charge or power your iPod independently without being plugged into your computer's USB port. That would be "way cool," but it is NOT happening with this product. Some of the confusion is on the part of the manufacturer. Unlabeled switches are NOT helpful and the instructions included could be more clear. To clarify:

If the hub is plugged into the computer there should be a blue indicator lit. In regards to the tiny switch on the side which controls when the batteries are in use, up is ON, and down is OFF in relationship to the unit. If the labels read right side up (front or back) then when the switch is up it is ON and the batteries will NOT recharge as they are being used to supply current to the hub.

If the switch is up, (ON) the red light is lit and the red light means the batteries are in use and are NOT charging. Until you switch the batteries OFF they will not re-charge. (If you remove the batteries the red light stays lit without the batteries because the charging voltage is still at the battery terminals and at the light. I believe this is a design flaw, but maybe it was intentional as a reminder that the batteries are not recharging. Note "First Time Use" instructions for charging the batteries.

Although the instructions are poor with a lack of proper labeling on the unit, the product itself is actually innovative, and a good addition to a notebook computer bag.
