I have been putting the Nomad 16,000 mAh power bank through its paces. As you can imagine, it is a bit of a beast, and it has some tricks up its sleeve.
The Nomad power bank has four output options: 5V, 12V, 16V, and 19V. The 5V output is via USB cable, while the other three are available via a supplied cable and adapter ports for laptop charging.
Charging A Laptop
Charging a laptop requires a supplied cable and any of the supplied adapters. The test laptop was a HP Pavilion G6 with a 15.6-inch display, Intel Pentium 2.40 GHz, and 4GB RAM.
I have been unable to determine the battery rating. I eventually pulled out the laptop’s battery and confirmed the rating to be 4200 mAh. This should mean that the Nomad 16000 mAh power bank should be able to charge it full four times if the laptop is switched off during charging. But no-one hardly ever does that. Question is, how does it perform with the laptop on and running?
PC charging offers you three options: 12V, 16V and 19V. Toggling between the three when connected to the Pavilion yielded differing results, as follows:
- 12V: no impact at all on the laptop
- 16V: maintains the laptop at its current level
- 19V: charges the laptop
Apparently, the experience will differ from laptop to laptop. Also Note that the HP Pavilion G6 has the “ExpressCharge” feature that lets its battery charge super fast within 30 minutes to 1 hour.
So, pegging the output to 19V, charging took off at 3.51 pm with the laptop battery at 10%. The laptop was on and a number of software were open, including Chrome, Internet Explorer and File Manager. There was no active internet connection during the process though. The unit stopped charging at 4.55 pm when the laptop battery hit 76%. That’s one hour and 4 minutes of charging and the laptop indicating that it has 3 hours 39 minutes of usage left. This still left the power bank with enough juice to still charge my BlackBerry Z30 for another 20 minutes, at which point it was drained completely. Not bad.
Charging A Mobile Device
When charging a mobile device via the USB port, output is 5V. Most devices don’t need more than 5V, and that’s what most other power banks provide. The Nomad is able to charge up the Z30 at least 5 times if its switched off during charging. I haven’t pushed it hard for charging my Z30, but considering its capacity and how well it works with a laptop, I doubt that I have anything to worry about that.
The sales pack included a range of accessories, including a charging cable, PC power connecting cable, and a set of adapters.
The Nomad 16000 mAh power bank is clearly in a class of its own. It costs N18,000. To order your unit or any of the other models in the Nomad line up, call Tinitop Technologies on 08023249636.
