HYDRALIGHT Oct 30 2016

Say goodbye to batteries — the Hydralight uses salt water to power its energy cells. This unique, patent pending technology aims to reduce battery waste and provide for an environmentally friendly power source that is both effective and reliable.

This new line of Hydralight products is powered by water-activated hydracell energy cells. The Hydralight incorporates a commonplace alloy and other eco-friendly elements that when hydrated instantly produce a steady flow of electric current. The current is maintained at the same level throughout the lifetime of the cell. No more fading headlamps and dimming flashlights — the Hydralight makes battery-powered woes obsolete.

The technology involves a simple ion exchange that is activated by ordinary salt water. To switch it on, simply remove the Hydralight cell from the lantern, dip it in salt water for 10-15 seconds, and replace it back into the hydracell for hours of instantaneous light and power. Just a few dips in water can charge the cell for days, providing over 250 hours of power.

The Hydralight is ideal for car camping trips, off-the-grid adventures, boating, and especially activities by the sea, as the ocean provides for an endless supply of power. And when you’re not near the sea, all you need to do is combine a cup of water with a few tablespoons of salt and dip in the hydracell for an equivalent source of power.

This eco-friendly, energy-efficient technology is delivered in a rugged, portable, and adaptable form. The products are designed to be used in any temperature or weather condition, rain or shine. Gone are the dark days when you realize you’ve forgotten your extra batteries for a camping trip — now you just add water.

These durable cells can be stored when dry prior to initial use for more than 25 years. Once activated, the cells can be dipped repeatedly, and are easily refurbished as well. Not only does the Hydralight provide for hours of light, but the product is integrated with USB ports for charging cell phones and other compatible devices.

The product line includes a supercell combination lantern/charger, personal lantern, utility lantern, utility downlight, and an accessory light. The company also offers two styles of flashlights as well as a utility powerpack. Everything is listed on the Hydralight website.

Best pressure washer deals: Up to $110 off Greenworks and Kärcher

The Greenworks GPW3001 Pro electric pressure washer, placed outside.

If you've been on the internet and seen a bunch of pressure washer clips and are now considering grabbing one yourself, you'll be happy to know that there is a huge range of them to pick from. That includes some great budget-oriented versions to dip your toe in and are still good for cleaning stains and cleaning up stuff. That's why we've gone out and collected some of our favorite washer deals for you below, including some of the best pressure washers for cars, which you do have to be a bit careful with not to strip the paint or clearcoat.
Greenworks Pressure Washer Combo Kit -- $110 $220 50% off

While this Greenworks power washer doesn't have as high a PSI, around 1,900 PSI, it is a lot more portable and a great option if you want something that's smaller and easier to take around with you. It comes with a 35-foot power chord and a 20-foot hose, so you get quite a bit of distance. If you are somewhere rural and need to clean stuff that doesn't have a power cable nearby, this is perfect. Besides that, we also appreciate that this comes with an 11-inch surface cleaner, which isn't something common with a lot of other power washers, even more expensive ones. Just be aware that you do need a My Best Buy subscription to be able to get the discount.

Juiced Bikes sold at auction for $1.2 million, report says

The Juiced Bikes Scorpion X2 adds more power, upgraded tires, and an improved battery to the popular moped style e-bike.

Juiced Bikes, the San Diego-based maker of e-bikes, has been sold on an auction website for $1,225,000, according to a report from Electrek.Digital Trends recently reported how the company was showing signs of being on the brink of bankruptcy. The company and its executives had remained silent, while customer inquiries went unanswered and its website showed all products were out of stock. In addition, there were numerous reports of layoffs at the company.Yet, the most convincing sign was that the company’s assets appeared as listed for sale on an auction website used by companies that go out of business.Now, it appears that Juiced Bikes’ assets, including a dozen patents, multiple URLs, and the company’s inventory in both the U.S. and China, have been sold at auction, according to the report. It is likely that the buyer, who remains unknown, can capitalize on the brand and the overall value of the 15-year old company. Founded in 2009 by Tora Harris, a U.S. high-jump Olympian, Juiced Bikes was one of the early pioneers of the direct-to-consumer e-bike brands in the U.S. market.
The company had quickly built a reputation for the versatility of its e-bikes and the durability of their batteries. Over the years, the popularity of models such as the CrossCurrent, HyperScrambler, and RipCurrent only bolstered the brand’s status.Last year, Digital Trends named the Juiced Bikes Scorpion X2 as the best moped-style e-bike for 2023, citing its versatility, rich feature set, and performance.Juiced Bikes’ getting sold quickly might be a sign of what consulting firm Houlihan Lokey says is a recovery in the North American e-bike market.
The industry has had a roller-coaster ride during and after the COVID-19 pandemic: A huge spike in demand for e-bikes had combined with disrupted supply chains to create a supply/demand mismatch of “historic proportions," Houlihan Lokey said.
