Worry no more about dead batteries as Oukitel is releasing another phone with a ridiculously large battery in a small rigid casing!

The Energizer P18K is pretty thick to accommodate the large 18,000mAh battery. Oukitel has also released a phone with a large battery, the WP15.

Oukitel is a brand you may not be familiar with but they are a smartphone company mainly selling rugged phones. These phones are built to last, intended for outdoor or torturous situations. They often carry the highest IP ratings, a toughened back similar to a $2 hard case, and every part inside is watertight. They also almost always carry a military-level classification.

Oukitel made headlines as they announced releasing a phone with a huge-ass battery by the end of June. It’s called the WP19. Although, this isn’t the first time they have released something so outlandish, with the WP15 having a 15,600mAh battery. Also, if you can recall, Energizer announced a crowdfunding program intended to mass-produce a heavy, brick-like phone with an 18,000mAh battery. However, this crowdfunding failed and thus the phone was subsequently canceled.

Battery aside, the phone is a typical midranger (apart from the ruggedness of it). It has a 6.78″ FullHD+ (2400x1080px) IPS LCD screen with 90Hz refresh rate. The phone uses a now-aging Helio G95 chipset coupled with 8GB RAM and 256GB storage.

The cameras are similar to phones you are familiar with, with one exception. The primary camera has a 64MP resolution. The second camera is a 20MP IR night vision camera with 4 IR emitters with a range of 20 meters. The last camera is the basic 2mp macro. It comes with a punch-hole notch that is used for the 16mp snapper.

As a rugged phone, it comes with an IP69K classification, the highest attained for any type of device. It also has a MIL-STD-810G standard. This guarantees your phone won’t die if you somehow decide to toss it 15 meters away.

We all know about the 21,000mAh battery. But how fast does it charge? It has 27W fast charging. This might seem slow for a battery this large. (It is). However, at least it only takes four hours to charge and not an entire day, so that’s still impressive. According to GIzmoChina, on average, the phone should last about 94 days on standby, up to 122 hours of continuous calling, and we’re calling it quits if ever actually calls that long; and 36 hours of video playback. This is quite an impressive feat and should be expected. What we’re still confused about is how Oukitel managed to install a battery this large on an already-cramped space.

While it is not officially here in the Philippines, and never will be, it is available via AliExpress for USD 599.99 (~Php 31.7K) . Although, we’re expecting it to be available on Oukitel’s official Lazada store. Because Oukitel does not have a post here in the Philippines; servicing, warranty, and replacement are a huge liability. Oukitel sells the WP15 for Php15,999 and comes with a Dimensity 700 chipset. The WP19 is actually a downgrade in terms of performance, but the larger battery and better screen should compensate for it.

Oukitel is also holding a giveaway that will last until 27th June. The winner receives a FREE Oukitel WP19. Simply head to their website for details!
