Harmonica Style Portable External Battery Pack Power Bank

The concept of a portable power bank/emergency charger isn't new, of course, especially in these days of smartphones with sealed batteries, for which the only emergency option is usually to plug something in via microUSB. The Lumsing 10400mAh option is new and reviewed here - build quality is excellent and - I contend - the value for money utterly unrivalled.

 

The unit Build quality is tremendous, though the brushed aluminium effect for the fascia is actually just that, an effect, with the whole unit being plastic. It's very solid though, with no creaks or worries, and the visual contrast of the gloss body and the mock-aluminium is striking.

On the left is a standard microUSB port for charging the Lumsing unit, a process which is best done overnight, since there's 10400mAh of cells inside to charge up, which will take a while on a typical smartphone wall charger - best not to do this on a laptop USB connection, since it will take around a day!

There's no wall charger supplied with the Lumsing, which seems fair enough, given the price point, but it does mean that actual recharging times will vary hugely depending on your cable and charger.

Supplied with the power bank charger is a white USB to microUSB cable, which can be used for the aforementioned recharging, or to dispense charge via either of the two outputs (labelled 1A and 2.1A, the latter nominally for a tablet). Interestingly, it seems as if you can both recharge and charge at the same time, i.e. you can have the Lumsing 10400 mAh bank plugged into the wall, being topped up, while simultaneously charging two phones via two other cables. Then, when you want to head out, you grab just the Lumsing and one cable, etc.
