I resurrected my four-years old (still snappy as new) Google Nexus 4 to be able to test these as my neither of my daily-drivers, Oneplus 2 and iPad mini use Micro USB. After thorough testing for over a week from most of the possible angles, I’ve reached conclusion for both the products – 3A Safety Car Charger and a one-meter USB to Micro USB cable.
Blaupunkt Micro USB Cable:
While the cable has not been rated to specific current ratings, it was able to efficiently deliver current up to 800 milli-amperes while charging (tested using Ampere App). This was tested using two stock wall bricks – 1.2A charger from Lenovo and 2A one from Oneplus. What this means is that a 2400 mAH (a unit for battery charge capacity) battery will be charged in at least 3 hours. There is no verbal indication of fast-charging capabilities.
Transfer speeds were in the range of 9.5mbps while sending data from PC to phone, and 16mbps from phone to PC. The cable’s MRP is marked at Rs. 499, but it is available for Rs. 249 on Amazon.in.
Given that other Micro USB cables with similar prices host options like fast charging up to 2.4A and transfer speeds of maximum 480mbps, this is one of the overpriced options available. On the pros side, the one-meter long cable seems durable.
Blaupunkt Dual Car Charger:
This energizes not just your battery but also your self-rescue missions in case of emergencies with a needle hammer for breaking the glass, as well as a seatbelt cutter. Not that of survival instincts fans? You can also use it to charge two devices simultaneously, with two ports – one on either side.
Each port charges without interference from others. While charging Nexus 4 with the Blaupunkt Micro USB Cable, the maximum current was clocked at nearly 800 mA, whereas it reached 1000 mA while charging my Oneplus Two using type-C cable. Now, this charging speed is not spectacular, but it can provide ample energy to keep your device from running out of juice, especially while navigation or other battery hungry tasks.
Again, following the trend, it is priced at maximum of Rs. 1,099, it is listed at nearly half i.e. Rs. 599 on Amazon.in. Each port is rated at max of 2.4A separately, while maximum output is 3A while charging two devices together, with no clear indication for Fast charging. So you better slow down if you have two power hungry devices beast batteries.
