The latest foldable phone comes courtesy of Energizer

Phone manufacturers like Huawei and Samsung have already launched foldable phones this month, and joining them is now battery manufacturer Energizer.

At MWC 2019 in Barcelona, the company launched a slew of new phones including the Power Max 8100S which looks intriguing. That said, it probably won't pose much competition to the Samsung Galaxy Fold or Huawei Mate X.

The Energizer Power Max 8100S comes with a dual-lens rear camera consisting of a 48MP main sensor and 12MP secondary snapper. There's also a selfie-cam of 24MP. All of the cameras are visible on the same side of the device – the inside tablet screen therefore has no cameras.

Energizer's phones are unique for their massive batteries. The Power Max 8100S launched alongside the Power Max 18K Pop, which has a huge 18,000mAh battery. 

Energizer's foldable doesn't have that much power, but its 10,000mAh power pack is still likely to lap both the Samsung Galaxy Fold's 4,380mAh or the Huawei Mate X's 4,500mAh cells.

The device is powered by a Qualcomm Snapdragon 855 chipset, and has 8GB RAM as well as 256GB internal memory, which makes it just as powerful as its foldable rivals but with a little less storage.

The Energizer Power Max 8100S was unveiled behind a glass case, and so we couldn't get hands-on with the device to see how it runs. For now we can't tell if it'll totally suck or not.

Energizer doesn't always bring its phones to every market either. For example, last year's Power Max 16K Pro was an intriguing solution to solving your battery life woes, but it never arrived in the UK.

Curiously we weren't shown a glimpse of the larger foldable screen on the new device. Only the normal screen and rear of the device were visible. This 6-inch 18:9 display had no notch and the camera sits inside the top bezel, but the screen we saw was likely a sticker (judging by other phones Energizer had on display) so we can't really tell the quality of it. The unseen screen is a 8.1-inch 4:3 Full HD foldable display.

It may be a while until we can get our hands properly on the Power Max 8100S too as this is almost certainly a prototype on show at MWC.
