Waterproof smartphones are cool and all, but every gadget meets its match when the battery is dead and you’re miles away from the nearest outlet. If you’re out in the rough or near water, then carrying a fragile external battery is risky. Poseidon is a new rugged external battery designed to survive those tough environments.

Poseidon is, as far as we know, the first IP68, MIL-spec external battery out there. What this means is that the external battery is designed to be just as rugged as a Panasonic Toughbook, and waterproof. The unit can survive up to four minutes of submersion, as well as any drops or tumbles that any other external battery would likely shatter into pieces. In fact, the Poseidon even survived being blasted by a shotgun 35 feet away.

Dark Energy, the team that designed Poseidon, advertises it as a great choice for GoPro users, as it can go pretty much anywhere you’d take your GoPro. The Poseidon’s metal casing is designed to maximize your grip on it, but also makes us wonder what would happen if the Poseidon’s battery overheated – which usually causes devices like smartphones to explode.

If you’re interested, you can check out the Poseidon portable external battery on Kickstarter. At $89, it’s about four time what you’d pay for a waterproof external battery, but would probably last a lot longer (as long as the battery doesn’t fail). The folks behind it hope to deliver the product this summer in time for your beach and fishing trips.

Vivo V15 Pro impressions

Vivo has made another leap forward in battery charging technology with the introduction of Super FlashCharge 120w, which is capable of sending enough power through to your phone’s battery cell to recharge it in only 13 minutes. The new system has been introduced at MWC Shanghai, which is currently taking place in China.

The name gives away part of the reason Super FlashCharge is so powerful -- it delivers 120w of power to compatible phones and batteries, using a specially customized USB Type-C cable, and a Super FlashCharge travel charger wall plug. The system works on 20v/6A. In its tests, Vivo says a 4,000mAh battery has been recharged from zero to 100% in only 13 minutes, with 50% coming up in an almost unfeasibly quick five minutes.

The OnePlus Watch 2 is the Wear OS smartwatch I’ve been waiting for

The OnePlus Watch 2 -- the company's first Wear OS watch -- has entered a market that Samsung dominates. However, OnePlus' popularity as a smartphone brand can be expected to bring small, yet meaningful changes that benefit not only OnePlus users, but all of the Wear OS segment in general.

For almost a decade, Samsung and Apple have predominantly been the default options if you want a smartwatch that is actually useful and goes beyond flashy features. With Samsung shifting gears and migrating from its own Tizen OS to the (relatively) more universal Wear OS platform and Google releasing its own Pixel Watch after struggling with an identity crisis in the smartwatch world, the platform has much more traction than it did a few years ago. As OnePlus carves its way into the segment, it has the opportunity to entice people who don't wish to live within Samsung's limitations when using a Galaxy Watch with another brand's phone.
