The Idapt i1 Eco is the portable member of Idapt’s family of universal chargers: by using the same interchangeable tips as the dual and triple versions, the usefulness of the system is extended from the home to the car and travel.

If you aren’t familiar with Idapt, their system offers a wide selection of charging tips that are snapped into a charging station which has anything from one (i1 Eco) to three (i4) changeable charging points. The benefit is that the charging station can be uniquely customised to your mobile device usage. For example, your phone might have a micro-USB connector, your iPod has an Apple connector and your Nintendo DSi has its own connector. By using the relevant tips, all three devices can be charged at once. Geek News Central reviewed the Idapt i4 earlier in the year.

Within this context, let’s take a look at the i1 Eco. Out of the box, you get a the i1 unit itself, a mains power connector, a USB power connector, a car USB adaptor and three charging tips – mini-USB, micro-USB and Apple.

The main unit takes only one of these at a time, but there’s an additional full-size USB port on the side, so two devices can be charged simultaneously.

The i1 Eco can be powered either from the mains or from a USB power source: the cables interchange at the lime green coloured multi-connector. As you can see from the picture below, these are standard connector types, namely micro-USB and IEC “shotgun”.

The power transformer is incorporated into the body of the Eco 1 so there’s no “wall wart”, only an ordinary plug on the end of the cable. The advantage of this will become clear shortly and when buying the i1 Eco, UK, USA or Euro mains plugs can be specified.

At the other end of the Eco 1 is the socket for the charging tips. These pop in and out and are exactly the same as the ones used in the tabletop models, which is handy if you have invested in a range of tips.

The USB socket on the side is used to charge a second device via a cable, which is best used for tablets or other larger devices which can be unwieldy to connect on the end of the i1 Eco.

As might be guessed from the name, it’s intended to be a green charger. The packaging is all recycled cardboard and the body of the i1 Eco is made from recycled plastic. Even more unusual is the presence of a power button on the side of the i1 Eco, which is there to help save energy.

Most consumer electronics chargers don’t have an on-off switch and most gang extension sockets don’t have on-off switches either, which means that to fully turn off a charger, it has to be pulled out of the socket, which is pretty inconvenient and most of us don’t bother. The chargers continue to consume power even when there’s no device being charged and this power is completely wasted.

The i1 Eco eliminates this problem by having an on-off switch and by automatically powering off when the recharging gadgets are fully charged. This is a great feature and as a result, no power is wasted when gadgets are connected but fully charged and the Eco 1 can be safely plugged in all the time.

Overall, it’s all very clever, useful and green to boot!

Are there any downsides? There are a couple but nothing too serious. First of all, the USB car adaptor that goes in the cigarette lighter socket is a bit flimsy and lets the overall package down. For comparison, the Griffin PowerJolt is a far better adaptor.

Secondly, the auto-power off feature is sometimes a bit over-enthusiastic. On occasion I’d connect up my tablet (Motorola Xoom 2 ME) to charge and I’d come back later to find that the i1 Eco had switched off while the tablet was still only part charged. Other times it worked perfectly with the tablet and I had no problems with other devices (Bluetooth headset, mp3 player, ereader). To be fair, the included literature does mention that some smartphones can be incompatible with this feature so I guess this includes tablets too.

Update: Idapt contacted me to say that with troublesome devices, simply hold the on-off button down for about a second when turning the charger on and this reduces the auto-off sensitivity. I carried out some further testing of the i1 Eco with the tablet and can confirm that this solution works so problem solved. Thanks, Idapt.

The i1 Eco is a clever and flexible portable charging solution that will particularly appeal to those who have already bought into the Idapt way and have a full set of charging tips.

The i1 Eco is available from Idapt for £19.99 and extra tips are mostly £5.95.

Thanks to Idapt for providing the i1 Eco for review.
