I get regular requests to review power banks, and so I only agree to review those that stand out. The Romoss Sense 6 LED power bank piqued my interest because of its huge capacity – a whopping 20,000 milliamp-hours (mAh).
I use my existing power banks regularly. Christine and I have one in each bag, so that we don’t have the risk of running out of phone battery when out and about. Seeing as we both play Pokémon Go, which uses a lot of battery power, having a power bank available is really important.
To put into context how big 20,000 mAh is, my iPhone 5S has a 1560 mAh battery. More modern smartphones have bigger batteries, like the Google Pixel XL, which has a 3,450 mAh battery. Still, the Romoss Sense 6 LED can charge even the newest phones several times over. It even claims to be able to charge a 9.7-inch iPad Pro 1.5 times.
This makes the Romoss Sense 6 LED ideal for trips where you will be away from mains electricity for extended periods of time, such as camping holidays or festivals. Though you may still want take a cheaper ‘festival phone’ for the latter.
Another feature which sets the Romoss Sense 6 LED aside from other power banks is its LED display, showing how much charge remains. This is a three digit display, showing 100 when fully charged, and a flashing ‘c’ whilst charging. Many other power banks have a simple row of LEDs that give an estimation of the charge, but this can be inaccurate by as much as 24%. And some don’t show their status at all. Being able to see exactly how much charge remains is really useful.
The large capacity of the Romoss Sense 6 LED power bank comes with a couple of trade-offs: size and weight. This is a big power bank: 16 x 8 cm (6.2 x 3.15 inches), and it weighs around half a kilo, or a little over one pound in old money. It feels a bit like an older laptop battery. It’ll also take around 13 hours to fully recharge.
That being said, it feels solidly built, with a white tactile plastic finish. Two USB ports are provided, one with a 1 Amp output and the second with a faster 2.1 Amp output. The microprocessor on board should be able to deliver the optimum current for each device, to minimise charging time. In my tests with my iPhone 5S, it charged just as fast as it would do plugged into a wall charger.
In the box with the power bank is a short manual and a USB type-A to micro-USB cable., This can be used for charging the power bank itself, or a device with a micro-USB port. You’ll need to use your existing cables for any other devices like iPhones.
The Romoss Sense 6 LED power bank is currently on sale at Amazon for £22, which is a bargain – you get a huge amount of power for your money. Weight aside, with this power bank you’re unlikely to ever need to scramble to find a AC power outlet when out and about again.
