Like magic, PompAdaptor claims to be able to take the old USB 2.0 standard 500mA (or more) and boost it up to 2.1A – suitable for tablets and an increasing range of devices that need more juice.
iTWire is not sure how it works – electronically that is – but tested a device back in 2013 with a similar claim, the iStyle PowerPill and it worked. It is no longer available.
PompAdaptor seems to be a later take on this – using a smart IC and a digital readout to show the amperage and voltage delivered. It is still a male/female USB-A adaptor, and you can plug in your existing USB, Lightning or USB-C cable.
The IC prevents overcharging – called smart detach – and can shorten charge times by providing a higher amperage. Electronically using a higher amperage should not harm the device – it is only concerned with getting the right voltage.
Indigogo is a crowdsourcing site – people contribute to good ideas that may or may not pay off. At present 229 backers have contributed US$11,340 and of course, PompAdaptor needs more - $35,000 is the goal.
For as little as $19 you can get a single adaptor, and that price includes worldwide shipping. They are looking for stockists (initial order 100) and distributors (initial order 200).
Given that the technology seems to work and given that there are so many generic 500mA chargers still in use it could be an interesting device.
