Rad Power’s Memorial Day Sale offers first cash savings on new e-bikes along with legacy models – starting from $1,299
Rad Power has launched its Memorial Day Sale through June 4, which is offering up to $500 off seven e-bikes, including the first cash discounts on four of its newest e-bikes that will be ending sooner on May 26. Among the new models, the one that has had my eye since its launch at the top of March is the Radster Road Commuter e-bike that is down at $1,999 shipped. This new model has been keeping to its $2,199 full price since hitting the market, with the only deals we’ve seen so far having been single add-on accessory promos during some past sales. You’ll now be able to save $200 off the going rate through next week’s holiday, setting the bar for future discounts that we might see down the road.
Launched alongside three other models, including a trail-trekking counterpart, Rad Power’s Radster Road e-bike is the latest of the brand’s commuter-focused solutions that boast a sizeable speed and mileage increase over its legacy models. It arrives equipped with a 750W rear hub motor that produces 100Nm of torque and a 720Wh Safe Shield semi-integrated battery, providing you with top speeds up to 28 MPH and up to 65+ miles of travel on a single charge with its 5 PAS levels activated (with those supported by a torque sensor).

This model, like its newer counterparts, comes stocked with some solid features beyond its initial performance, like the system locking via a passcode or an included security fob, providing added security, which is always my primary concern when taking mine out. There’s also the hydraulic suspension fork, hydraulic disc brakes, Kenda Kwick puncture-protected tires with fenders over each, the front LED headlight and integrated taillight with brake lighting and turn signals, a Shimano 8-speed derailleur, a rear cargo rack, a color display with a USB-C port to charge devices, and more.

Keep your outdoor adventures running with DJI’s Power 1000 1,024Wh LiFePO4 station down at $449
Through its official Amazon storefront, DJI is offering its Power 1000 Portable Power Station for $449 shipped. Despite carrying a $999 price tag elsewhere, we’ve been seeing it spend 2025 so far keeping posted at a $699 rate here at Amazon, with discounts having been completely absent since April began. While we have seen it dip down as low as $379 in the past, those rates were last seen in November and December, with the price here beaten out in the new year by one fall to $419 in March, giving you the second-best pricing of 2025 that saves you $250 off the going rate ($550 off its original MSRP). It’s even beating out the discount we’re seeing directly from DJI’s website, where it’s sitting $50 higher.
An ideal companion for folks who spend plenty of time out in the wilds of the world, particularly for photography, flying the brand’s drones, and the like, DJI’s Power 1000 station covers backup power needs with a 1,024Wh LiFePO4 capacity through eight port options. Those ports are quite versatile in output, as among the options you’ll have, the two AC outlets provide up to 2,200W of power (surging to 2,600W) in order to tackle larger appliance needs, while also promising fast-charging speeds for personal devices at up to 140W from the dual USB-Cs, plus the others.
By equipping this station with either an MPPT module or DJI’s power outlet to SDC power cable, you’ll be able to utilize its solar-charging capabilities, with the unit boasting a 1,600W max input that can put the battery back to full in 80 minutes. Of course, you could also plug it into a wall outlet for an 80% battery in 50 minutes, taking about 20 minutes longer to push it to full. Right now, there are two discounted solar-capable bundles, with the station getting a 100W panel and the appropriate cables for $688, down from $1,247, or, while it has been $300 less for most of the year, you can still save $300 off the MSRP for the station with a 200W panel at $1,356. There are other options on the same page for those just seeking the cables to connect existing solar panels, but they are keeping to their full prices at the moment.
Fell trees and cut up firewood with Husqvarna’s Power Axe 350i 18-inch electric chainsaw kit at $384
Amazon is offering the Husqvarna Power Axe 350i 18-inch Cordless Electric Chainsaw for $383.99 shipped. Normally going for $480 at full price, discounts are often less frequent on this brand’s tools as opposed to EGO, Greenworks, and others. In 2025, we’ve seen it fall to this same rate twice before, which has been the lowest tracked price so far in the last five months. We have seen it go as low as $359 at the end of 2023, and $379 in 2024, with today’s deal being the best of 2025 and the third-lowest price overall, saving you $96 off the going rate for as long as it lasts.
Unlike many other Husqvarna offers we see, which are usually tool-only deals, the brand’s Power Axe 350i actually comes with a 7.5Ah battery and charger, and is a larger yet still lightweight model perfect for felling trees, cutting up firewood, and the like with its 18-inch bar and chain. It has been given the brand’s X-cut chain that retains sharpness for longer periods over more standard designs, while also boasting a tool-less tensioning system that allows for easier adjustments at faster speeds with little effort. There’s even a boost mode that activates with a button press, ramping its output by 25%.

Get up to 30% off EcoFlow flash offers like the DELTA 3 Plus power station with a protective bag at $649 (Today only)
As part of EcoFlow’s ongoing Memorial Day Sale through May 28, the brand has launched the next round of 24-hour flash offers on three units through the rest of the day. The only one to include an actual power station gives you the DELTA 3 Plus with a protective bag for $649 shipped. We normally see this bundle with the bag on the standard predecessor model or elsewhere, with the power station often fetching $799 at full price. While we have seen the price go as low as $535 from a Wellbots exclusive deal last month (one of only two that we’ve secured), you’re still looking at a solid $150 markdown off the going rate on top of getting the accompanying bag, which is lacking at Amazon, where the pricing on the station matches.
While not as sizeable as some of its counterparts, EcoFlow’s DELTA 3 Plus is a mid-range option that gives you peace of mind while away from home with its 1,024Wh LiFePO4 capacity, which you can expand up to 5kWh with the appropriate expansion batteries for the DELTA 3, DELTA Pro 3, DELTA 2 Max, or the DELTA 2. The 13 ports provide ample support for devices and appliances, with the unit dishing out a steady 1,800W output that can surge as high as 3,600W thanks to the X-Boost. There are five methods to recharge this model (AC, solar, smart dual fuel generator, 800W alternator charger, and multi-charging), and it comes rated for 4,000 lifecycles, giving you nearly 11 years of usage, were you to charge and discharge its battery every single day.

The savings this week are also continuing to a collection of other markdowns. To the same tune as the offers above, these all help you take a more energy-conscious approach to your routine. Winter means you can lock in even better off-season price cuts on electric tools for the lawn while saving on EVs and tons of other gear.
Today was the official start of racing at the Electrek Formula Sun Grand Prix 2025! There was a tremendous energy (and heat) on the ground at NCM Motorsports Park as nearly a dozen teams took to the track. Currently, as of writing, Stanford is ranked #1 in the SOV (Single-Occupant Vehicle) class with 68 registered laps. However, the fastest lap so far belongs to UC Berkeley, which clocked a 4:45 on the 3.15-mile track. That’s an average speed of just under 40 mph on nothing but solar energy. Not bad!
In the MOV (Multi-Occupant Vehicle) class, Polytechnique Montréal is narrowly ahead of Appalachian State by just 4 laps. At last year’s formula sun race, Polytechnique Montréal took first place overall in this class, and the team hopes to repeat that success. It’s still too early for prediction though, and anything can happen between now and the final day of racing on Saturday.
Congrats to the teams that made it on track today. We look forward to seeing even more out there tomorrow. In the meantime, here are some shots from today via the event’s wonderful photographer Cora Kennedy.

Tesla has launched its new Oasis Supercharger, the long-promised EV charging station of the future, with a solar farm and off-grid batteries.
Early in the deployment of the Supercharger network, Tesla promised to add solar arrays and batteries to the Supercharger stations, and CEO Elon Musk even said that most stations would be able to operate off-grid.
While Tesla did add solar and batteries to a few stations, the vast majority of them don’t have their own power system or have only minimal solar canopies.
Back in 2016, I asked Musk about this, and he said that it would now happen as Tesla had the “pieces now in place” with Supercharger V3, Powerpack V2, and SolarCity:

All of these pieces have been in place for years, and Tesla has now discontinued the Powerpack in favor of the Megapack. The Supercharger network is also transitioning to V4 stations.
Yet, solar and battery deployment haven’t accelerated much in the decade since Musk made that comment, but it is finally happening.
Tesla has now unveiled the project and turned on most of the Supercharger stalls:
The project consists of 168 chargers, with half of them currently operational, making it one of the largest Supercharger stations in the world. However, that’s not even the most notable aspect of it.
The station is equipped with 11 MW of ground-mounted solar panels and canopies, spanning 30 acres of land, and 10 Tesla Megapacks with a total energy storage capacity of 39 MWh.
It can be operated off-grid, which is the case right now, according to Tesla.
With off-grid operations, Tesla was about to bring 84 stalls online just in time for the Fourth of July travel weekend. The rest of the stalls and a lounge are going to open later this year.
Electrek’s Take
This is awesome. A bit late, but awesome. This is what charging stations should be like: fully powered by renewable energy.
Unfortunately, it will be much harder to open those stations in the future due to legislation that Trump and the Republican Party have just passed, which removes incentives for solar and energy storage, adds taxes on them, and removes incentives to build batteries – all things that have helped Tesla considerably over the last few years.
The US is likely going to have a few tough years for EV adoption and renewable energy deployment.
