What Makes the Energizer Power Max P18K Pop Worth Buying?
The Energizer Power Max P18K Pop is one of the most extreme battery phones ever announced. Revealed at MWC 2019, it grabbed headlines instantly — and for good reason. An 18,000 mAh battery in a smartphone is not a modest upgrade over the competition. It’s an entirely different category of device, one designed for people who measure battery anxiety in days, not hours.
To put that capacity in perspective: most flagship phones ship with batteries between 4,000 and 5,000 mAh. The P18K Pop carries more than three times that. For anyone who’s ever been stranded with a dead phone on a long trip, in the field, or at a multi-day event without reliable power access, the concept behind this phone is almost aspirational.
The spec sheet beyond the battery is genuinely solid for its era. It runs Android 9.0 Pie on a MediaTek Helio P70 chipset — a capable mid-range processor with four Cortex-A73 cores and four Cortex-A55 cores, all clocked at 2.0 GHz. The 6GB RAM and 128GB internal storage configuration is generous, and microSDXC expansion is supported for even more headroom. The 6.2-inch IPS LCD display runs at 1080 x 2280 pixels at ~407 ppi — crisp, detailed, and comfortable for long viewing sessions.
Camera coverage is respectable too. The rear triple-camera system leads with a 12 MP PDAF main sensor, supported by a 5 MP secondary lens and an auxiliary lens. On the front, a 16 MP wide-angle selfie camera pairs with a 2 MP depth sensor for portrait shots. There’s also 18W wired fast charging with PD 2.0 support, and a reverse charging feature at 2.5W that lets the phone top up other devices — essentially turning it into a power bank.

Things to Know Before Choosing the Energizer Power Max P18K Pop
The single most important thing to know about the Energizer Power Max P18K Pop: it was cancelled. Announced in February 2019, the device never made it to commercial release. Energizer cited manufacturing and engineering challenges — cramming an 18,000 mAh cell into a phone body was described as resulting in a device roughly 30–40 mm thick, which created real-world usability concerns. Anyone looking to purchase this phone should be aware that it is not available through official retail channels.
If a unit does appear on secondary markets, there are several practical limitations to keep in mind. The sheer physical size is unavoidable. A device 30–40 mm thick is closer to a small power bank with a phone screen than a conventional smartphone. It would be difficult to pocket, hold comfortably in one hand, or use with standard cases and accessories.
The software is another concern. Android 9.0 Pie was current in 2019, but it’s now several major Android versions behind. Security patches have long since stopped, and many modern apps no longer optimize for older Android releases. This is a significant drawback for anyone considering daily driver use.
There’s no NFC, which rules out contactless payments. The 3.5mm headphone jack is absent as well — a notable omission, especially on a phone where wireless audio would require Bluetooth. GPS and GLONASS are present, but more advanced satellite systems like Galileo and BDS are not listed. Video recording tops out at 1080p 30fps on both front and rear cameras, which is functional but not competitive with what most modern mid-range phones offer.
The reverse charging rate of 2.5W is also worth contextualizing: while the feature is conceptually appealing given the massive battery, 2.5W is extremely slow for charging another device. It works in a pinch, but it’s not a fast power bank replacement.
Is the Energizer Power Max P18K Pop Right for You?
Given its cancelled status, the P18K Pop is more of a collector’s curiosity and a fascinating engineering footnote than a practical daily phone recommendation. That said, understanding who the device was designed for helps frame what it was trying to achieve.
Extended field users — surveyors, expedition travelers, military personnel, or researchers working in remote areas — were clearly the target. A phone that could last a week or more without charging is genuinely transformative in situations where power infrastructure is unreliable or nonexistent.
Power bank enthusiasts who wanted one device to serve as both phone and external battery would have found the reverse charging feature conceptually compelling, even if the 2.5W output rate is modest.
Tech collectors and enthusiasts interested in extreme form-factor experiments will find the P18K Pop historically fascinating. It represents a moment where the question “how big can a smartphone battery get?” was pushed further than almost any other production-intended device.
For everyday buyers, students, gamers, or anyone seeking a capable modern smartphone, the P18K Pop is not the right choice — not only because of its cancelled status, but because its aged software, limited camera video resolution, absent NFC, and enormous physical dimensions would make it a frustrating daily companion by current standards.
Best Alternatives to the Energizer Power Max P18K Pop
For buyers drawn to the P18K Pop’s core appeal — extreme battery life — there are several active, purchasable options that deliver massive endurance without the compromises of a cancelled prototype:
- Oukitel WP22: A rugged Android phone with a 10,000 mAh battery, IP68/IP69K protection, infrared night vision camera, and MIL-STD-810H compliance — available and actively supported.
- Ulefone Power Armor 19:Â Another rugged contender with a large battery, modern Android, and outdoor-focused features including thermal imaging on select variants.
- Doogee V30:Â Offers a substantial battery with 5G connectivity, rugged build, and more current software support.
- Samsung Galaxy M53 5G: A mainstream option with a 5,000 mAh battery, 5G, and Samsung’s long-term update track record — better for general consumers who want longevity without the bulk.
Energizer Power Max P18K Pop Frequently Asked Questions
Is the Energizer Power Max P18K Pop available to buy?
No. The Energizer Power Max P18K Pop was announced in February 2019 but was ultimately cancelled before reaching commercial release. The primary challenge was its extraordinary thickness — estimated at 30–40 mm — which made mass production and practical daily use extremely difficult. It is not available through official retail channels, though rare units may occasionally surface on secondary markets.
How long would the 18,000 mAh battery actually last?
An 18,000 mAh battery in a mid-range phone would theoretically provide anywhere from five to ten days of regular use, depending on screen-on time, connectivity, and app usage. With the Helio P70 chipset and a 6.2-inch LCD display, light-to-moderate usage could realistically stretch a full week before needing a recharge. Heavy use — continuous streaming, navigation, or gaming — would drain it faster, but still far beyond what any standard smartphone offers.
Can the Energizer P18K Pop charge other devices?
Yes, it supports 2.5W reverse wired charging, which allows it to act as a power bank and top up other devices via the USB Type-C port. The rate is slow — 2.5W is not fast charging by any measure — but given the 18,000 mAh capacity, it can still meaningfully charge phones, earbuds, or other small accessories even at that output rate.
What Android version does the Energizer P18K Pop run?
The P18K Pop was announced running Android 9.0 Pie. As a cancelled device that never received official retail distribution, there is no update history or official upgrade path. Android 9 is now several major versions behind current releases, and most apps and security patches no longer actively support it.
Does the Energizer Power Max P18K Pop have NFC?
No. The P18K Pop does not include NFC, which means contactless payment systems like Google Pay are not supported. It also lacks an infrared port. The connectivity suite covers Wi-Fi 802.11 a/b/g/n/ac dual-band, Bluetooth 5.0 with A2DP and LE support, GPS, GLONASS, FM radio, and USB Type-C 2.0 with OTG.
