Although I was disappointed by the Nokia DT-900, I wasn’t ready to give up on wireless charging nirvana for my Nexus 4. With a bit of searching and review-reading, I plumped for a Zens Universal Qi Single Wireless Charging Plate which garners 4.5 stars on Amazon. Although unknown to me, Zens is a young Dutch company specialising in wireless charging products, and from first appearances, it looks like they’re doing a good job.
The Zens charging plate comes in a well-presented package but is surprisingly small. It’s bigger than the DT-900 but it’s still not large and I imagine that most large screen smartphones will overhang on one side or another. However, the extra size and the rubber covering mean that most smartphones will sit comfortably on the pad. As with the DT-900, it has a DC power supply – no USB charging here, either.
In use, the Zens charging plate is far better with the Nexus 4 than the DT-900. In most instances, simply placing the the Nexus onto the pad started charging and usually, I’d get a high rate of charge without any precise positioning. With a bit of practice, I was able to get a sweetspot that worked every time and an LED on the right side of the plate turns green when the pad starts charging.
The screenshot below shows the charging rate when everything is perfectly aligned and honestly, it’s not far off the rate when the Nexus is plugged in.
The plate also has a feature that when the phone is fully charged, the charging turns off until the the battery levels falls to about 93%. Here’s what it looks like in Battery+.
In my opinion, the Zens charging plate knocks the DT-900 into a cocked hat, especially if you have a Nexus 4. Both are priced a little under £45 here in the UK, though the Zens charger seems quite pricey in the US at $100 (Amazon). Update – have since discovered the Zens charger on other websites for a far more reasonable $50. Recommended for all UK Nexus 4 owners.
