The fast processors and large screens of modern day smartphones draw power like it’s going out of fashion. A battery that would have lasted several weeks in the Nokia 6210 now struggles to get through a day of calls, email and web surfing. And that’s before starting to play Ingress.
Desktop chargers have their place but sometimes it’s not possible to get back to a power outlet to plug in. External battery packs and chargers fill this space and on review here is the New Trent IMP120D external battery and charger. With a 12,000 mAh battery, it’s roughly 6 times the capacity of a smartphone battery and 3 times the size of a 7″ tablet’s. Physically, it’s around 9 x 9.5 x 2.5 cm and there’s bit of weight to it at 280g / 10 oz but it fits comfortably in the hand, especially with the soft curved edges of the 120D.
As the pictures show, it’s not unattractive for a battery pack and gets away from the standard rectangular brick. The black plastic enclosure has a blue central band with just four features – an on-off button, a power input socket and two USB ports. The on-off button lights up when charging and a short press of the button briefly shows the 120D’s charge level using three blue LEDs for low, medium and high.
Two USB sockets obviously allow two devices to be charged at once. One socket is rated at 1 A and the other at 2.1 A, which practically means that you can charge a phone and a tablet at the same time. In the box along with the IMP120D, there’s an AC wall charger, a USB to microUSB charging cable, a charging cable for Samsung devices and a soft carry pouch.
Unlike some other devices, it’s possible to charge both the IMP120D at the same time as it charges other devices, which means that when travelling, only the 120D’s charger needed to get everything charged up overnight – the battery pack plus two other devices. The 120D does take a good few hours to get itself charged up, which given the larger than average battery isn’t to be unexpected. There are some other handy features too. For example, the 120D automatically shuts off once attached devices are fully charged.
In use, the IMP120D can be simply used as a backup battery pack to recharge phones or other devices when their internal batteries get low. More usefully, the 120D can be used to extend the life of portable equipment such as personal wireless routers. My MiFi can run for a couple of hours on its own battery, but connect it up to the IMP120D and I can get a whole day of use out of the hotspot without any trouble at all.
Overall, the IMP120D is a very handy gadget, essential for any heavy smartphone user or frequent traveller. It’s competitively priced at around $70 in the USA or £40 in the UK. Recommended.
