Need a phone with supreme battery life? Chinese smartphone maker Oukitel has released an Android handset with a 10,000mAh battery.

Battery life has emerged as one of the chief complaints about smartphones whose lithium-ion cells can't keep pace with ever more powerful devices and bigger displays.

Apple, an advocate of smaller batteries over thicker phones, has answered complaints about the iPhone 6 and iPhone 6s battery with the new $99 Smart Battery Case, offering it similar longevity to the iPhone 6/6s Plus.

Some Android OEMs have recently packed 4,000mAh capacity batteries into new models, such as Huawei's new Mate 8 phablet and Xiaomi's $140 Redmi Note 3 phablet.

Oukitel, a Chinese smartphone company, promises to blitz the competition with a 10,000mAh battery said to last around 15 days on a single charge. And just in case the headline feature wasn't obvious, Oukitel has dubbed its device 'the K10000' after the battery's specs.

The company has released a number of big battery devices before. The K6000 was also named after its 6,000mAh battery, which Oukitel claimed offers a 10-day battery life and supports fast charging.

What else can you do with the K10000's supersize battery? As with the K6000's USB OTG reverse charge function, the K10000 can be used to juice up other devices.

A marketing stunt by Oukitel shows off how 10 K10000s can be wired up to cook a pot of instant noodles on an electric stove.

As noted by NDTV, the device is available for pre-order for $240, though the online retailer indicates deliveries are delayed and won't arrive until January 30.

The K10000 features a 5.5-inch HD display with a 1GHz MediaTek MT6735 system on chip and 2GB RAM. It comes with 16GB onboard storage and a microSD card slot that supports up to 32GB additional storage.

Oukitel has previously claimed it will come with a 13-megapixel (MP) main camera and 5MP selfie-shooter.

However, according to specs published by the online retailer, those are software-enhanced specs for 8MP and 2MP sensors, respectively. The device supports 4G FDD-LTE 800/1,800/2,100/2,600MHz and ships with Android 5.1 Lollipop.
