Prime Day may have come and gone, but we’re still seeing a series of notable offers in the green energy space. On tap today, the popular RadExpand 5 e-bike is falling to its best price yet at $1,399. That’s joined by some all-time lows on Jackery power stations at up to $700 off and so much more. Just don’t forget about all of the best e-bike discounts around.
Rad Power Bikes makes some of our favorite EVs across all of 9to5, and today we’re tracking a notable chance to save on one of its more compact offerings. The latest RadExpand 5 e-bike gets its name from a folding design that expands when it’s time to ride, and today you can expand some savings on the recent release. Normally the electric bike sells for $1,649, but right now you can bring it home for $1,399 shipped thanks to the summer savings this week. Those $250 in savings deliver a match of the all-time low for one of the first times while arriving at a new 2023 low.
Delivering a space-saving design, the RadExpand 5 merges all of the usual Rad Power Bikes features with a build that can fold closed when not in use. Its 750W electric motor can carry 275 pounds at up to 20 MPH over a 45-mile range, making it just as ideal for joyrides as it is for quick trips to the store. We found it to be a worthwhile option in our hands-on review from last spring. Though if you’re looking for something more full-featured, we highlight another discount below the fold.
Featured deal: Not to be outdone, EcoFlow is also offering some enticing Prime Day specials this year. Getting in on the summer saving festivities, the discounts this week deliver up to 51% in savings on the brand’s popular power stations, solar panels, and off-grid kits. The best prices of the year are live over the next several days, with the main Prime Day discounts launching for two days only on July 11 and 12.
We’re also able to offer an exclusive code electreckpd that adds an extra 5% in savings on top of the already-discounted items from EcoFlow.
Jackery power stations still at all-time lows
As part of its Prime Day 2023 deals, Amazon is offering the best prices of the year on Jackery portable power stations, solar panel kits, and more. Jackery makes some of our favorite portable power solutions at 9to5Toys, and now they’re even better values. Earlier this spring, Jackery expanded its lineup of popular portable power stations with the new Explorer 2000 Plus, and now its second-ever discount is arriving. Marked down by itself to $1,999 shipped, today’s offer arrives at $400 off. This is matching the Amazon all-time low and is only the second chance to save.
Everything with Jackery’s latest starts with the Explorer 2000 Plus itself. The new power station finally makes the switch away from the NCM batteries that have long been used by Jackery over to the longer lasting and safer LFP standard. As for how you’ll actually be able to leverage all of that power, the Jackery Explorer 2000 Plus comes outfitted with the kind of flagship roster of ports you’d expect from its latest and greatest. There’s four full AC outlets+ an RV friendly TT-30, as well as dual USB-A slots, a pair of 100W USB-C outputs, and a 12V car jack. There are also solar panel bundles at up to $700 off.
Featured deal: Bluetti is also stepping in to offer some notable Prime Day offers this week across its lineup of popular portable power stations and solar panels. Offering some of the best discounts to date, you’ll be able to secure a new off-grid package for tailgates and the like, as well as just having some extra power around the house.

After years of waiting and many falsestarts, Formula E is finally going to debut its mid-race charging system, which will give cars a quick boost of energy charging at a rate much faster than current road cars can.
For years now, we’ve been hearing about FIA plans to introduce charging stops to electric racing.
In gas car racing, some series allow mid-race fueling and some don’t. The World Endurance Championship, which runs the 24 Hours of Le Mans, obviously needs to fill up several times during the race. But Formula 1, which hosts shorter races, eliminated mid-race fueling in 2010.
But the FIA already had one electric racing series, Formula E, which had debuted in 2014. At the time, each driver had two cars, and would swap mid-race to a fresh car with new batteries.
Battery-swapping had been considered, but it would be too complicated to set up at temporary race facilities in city downtown areas, as many Formula E tracks are.
Then, in 2018, Formula E debuted a new “Gen 2” car which had a big enough battery not to need a charge mid-race, and later a “Gen 3” car in 2022, which had much stronger regenerative braking, capable of 600kW of braking power. Gen 3 also has an “Attack Mode” feature that lets cars unlock additional power for a short period each race, adding to strategy and mixing up the race order.
The issues involved building the charging system in temporary facilities and ensuring safety of the system (and of pit stops in general, which is always a concern when cars are driving rapidly near people). But after winter testing prior to this season, Formula E now says the system is ready to go.
So, once again, Formula E is ready to announce that mid-race charging is definitely, totally, positively, 100% certain at the upcoming Jeddah E-Prix, on February 14-15 in Jeddah, Saudi Arabia.
Formula E thinks that proving this high-power charging technology could help road cars to charge more quickly, which could have myriad benefits for electric cars in general.
The series is calling the system “Pit Boost,” and it will consist of a 34-second pit stop that provides around 10% additional charge to the cars (about 4kWh). While 10% isn’t a lot, 34 seconds is also not a lot of time. For comparison, one of the fastest-charging cars out there, the Ioniq 5, can charge from 10-80% in 18 minutes, which means 10% charge takes 2.5 minutes – five times as long as Formula E cars will manage the feat.
The stop will be mandatory for all drivers to take at some point in the race, and will mean new strategy options for drivers. Taking the stop means getting more energy, which means that your car won’t have to do as much energy saving to get to the end of the race – but it also means giving up your position on track, which can be hard to get back if you do it late in the race.
However, we’ve never seen it happen before, so it will be interesting to see what kind of strategic options develop.
If you’re interested in seeing how it turns out, tune in to the Jeddah E-Prix on February 14-15 to see what happens. It’s a doubleheader race weekend, with night races both on Saturday and Sunday, February 14-15, at 5pm UTC, 9am PST, 12pm EST, and 8pm local time. You can check out how to watch the race in your area by going to Formula E’s “Ways to Watch” section. In the US, Roku should be the most reliable way to watch.

JackRabbit, the maker of pint-sized electric microbikes, is back with a new product designed to quickly recharge their batteries from pure, uncut photons mainlined into an e-bike directly from the sun. In true independent charging form, the Solar Charging Kit from JackRabbit keeps riders rolling even when there’s not a convenient AC outlet in sight.
Unveiled this week, the Solar Charging Kit consists of a single folding solar panel and a tiny voltage converter that is configured to output 42.0V, which is the exact voltage required by JackRabbit’s little e-bike batteries. There’s also an added USB-A and a USB-C charging port for powering other devices in addition to charging JackRabbit batteries.
“This Solar Charging Kit plugs directly into your bike,” explained the company, “letting you recharge without needing an outlet, but with a speed comparable to the charger that comes with the OG/OG2 (42V, 2A).”
That would mean the panel outputs around 80W of solar power, which the company says can recharge its batteries in just three hours. That fairly quick recharging speed is helped by the fact that JackRabbit’s batteries are a mere 151 Wh, or around a third of the size of most e-bike batteries.
If that sounds small, then you’re right – it is. But JackRabbit is all about going micro, offering barely 25 lb rideables that are easy to store and bring on adventures, even when they aren’t actually being ridden.
With small batteries that fit under the 160Wh limit for many airlines in the US, the batteries can be quickly charged and taken to the widest number of locations. And for riders that want to go further than a single 10-mile (16-km) battery will allow, extra batteries are small enough to fit a pants pocket. The company also offers much larger Rangebuster batteries, though they won’t pass by TSA and make it onto an airplane in your personal item.
It sounds like the Solar Chargking Kit should be able to charge up JackRabbit’s large RangeBuster batteries, though likely in more than three hours.
The $349 Solar Charging Kit is a bit pricier than building something similar yourself, but it’s also safer and more convenient than hacking together your own battery charger since it’s designed to work with JackRabbit’s batteries right out of the box.
Technically it’s only inteded for JackRabbit’s micro e-bikes (themselves technically seated scooters, even if they look and feel more like a typical bike), but it’d probably work for just about any 36V e-bike that requires 42.0V to charge.
This isn’t the first time we’ve seen solar charging kits for electric bikes, and it’s a trend that is certainly appreciated by outdoors and camping enthusiasts, festival goers, or anyone who finds themself and their bike spending extended periods in the great, sunny outdoors.
