Today I’m reviewing the Proporta Turbo Charger 7000 which was kindly given to me to review by Proporta. I’d like to thank them for giving me the opportunity to test this device, and enable me to share my experience of the device with the readers of this blog.
Proporta’s range of Turbo Chargers have been around for quite a while, steadily going up in capacity over time from 3400 mAh, to 5000 mAh, eventually to a massive 7000 mAh. Your average smartphone has a battery capacity between 1200mAh to 1600mAh.
I tested the Turbo Charger 7000 with my Lumia 800 (1430mAh) and my Nexus 7 tablet (4350mAh) during a weekend away. The aim was to get through two days without taking power from the mains. Keep reading to find out whether that was successful or not!
Packaging and Features
The Turbo Charger comes in high quality packaging, in which you’ll find a suede drawstring bag which is supplied to contain the charger, two retractable USB cables and a range of charging tips for those cables.
The charging tips supplied are: 1 x DS Lite, 1 x iPod, 1 x Nokia, 1 x Sony Ericsson, 1 x Micro USB and 1 x Mini USB. I feel that it might have been better to include two Micro-USB adapters and two Apple adapters. However, in most cases you can use your own USB cables and ignore the supplied equipment – especially if you are worried about losing such small parts. The only exception I found with cable compatibility was on the Nexus 7 tablet. It will only take power from the Turbo Charger with the retractable USB cable and Micro USB adapter supplied.
Having a drawstring bag is ideal given the size of the Turbo Charger and its accessories. However, I would suggest Proporta use a different type of material in the future, as the suede used here was shedding lots of fibres. For my trip away, I used my own nylon drawstring bag.
The Turbo Charger has two full-size USB ports which enables you to charge two devices simultaneously. One port is labelled as “Low Power” supplying 0.5 Amps as with a computer port, and the “High Power” port supplies a whopping 2.1 Amps which is required to quickly charge the large batteries found in tablet devices like the iPad and Nexus 7.
The Turbo Charger is charged via a Micro-USB socket, which is found between the two full-sized USB output ports. A mains charger isn’t supplied because you really don’t need one. The charger supplied with a smartphone, tablet, or indeed any USB charger is suitable to recharge the Turbo Charger. However, there is a “World Travel Pack” in which the Turbo Charger 7000 is supplied with an international USB mains adapter.
As you might expect, recharging the Turbo Charger takes quite some time. How long depends on your charger. If you were recharging from a PC port, then you’d need to leave it overnight. However, if you have a high power charger, such as supplied with tablet devices, then you can charge from empty in around three hours.
There’s just one button on the Turbo Charger which serves a dual purpose. When a device is connected to the Turbo Charger, you need to use this button to begin charging. Also, pressing the button either before a device is connected or during charging, will trigger the four blue LEDs to display the charge level to you.
With there being only four LEDs, there is effectively a precision of 25% in the battery reading, but in practice that did not prove to be a serious issue.
When I took the Turbo Charger on my journey, I used the Lumia 800 as a Wi-Fi hotspot for the Nexus 7, while travelling on the train. To keep the Lumia 800 powered, I connected it to the high power port on the Turbo Charger, and the Nexus 7 to the lower power port to keep its battery topped up. This worked great, and by the time I was packing up my equipment, both devices were fully charged, and the Turbo charger was still displaying all four LEDs.
The first evening I was away, I connected both devices (Nexus 7 on high power this time) to recharge and run on external power from the Turbo Charger overnight. By the time I awoke, the Turbo Charger was showing two LEDs out of four, which means I had somewhere between 50% and 75%, probably close to the former.
During that next day, the Turbo Charger was used to exclusively top-up the Lumia 800 which was on intense camera duty, and mostly out of signal range, which meant it was using more power to try to keep in touch with the 3G and GSM network. Several hours of keeping the Lumia 800 topped up in this situation finally had the Turbo Charger down to its last LED.
Had I returned home that day as planned, I’m confident the Turbo Charger would have kept my devices topped up throughout. However, since I decided to stay over a second night, I did have to recharge it from the mains. Using it to keep my Lumia 800 and Nexus 7 topped up overnight again, it was back down to the two LEDs level by the next morning.
I am impressed with the Proporta Turbo Charger 7000. So much so, it’s now part of my essential tech kit whenever I go away for more than a day. For example, if I were staying away for a single night to cover a tech event, I feel that the Turbo Charger would enable me to take my tablet and a Bluetooth keyboard instead of my laptop, without a mains adapter. Similarly, if you’re going away for a few days and only need to keep your phone powered, again, the Turbo Charger 7000 will be an excellent device.
The Turbo Charger 7000 also would be invaluable in the home, if kept fully charged it would keep you connected during a prolonged power cut. I would even suggest keeping one in the glove box of your car – it could be a real life saver.
