Seamless Solar Compatibility, Supercharged
Meet the world's first 4kW solar charge controller. The BLUETTI SolarX 4K takes 150–500V from nearly any rooftop or ground array and converts it into safe, sub-60V charging for BLUETTI power stations—up to 4,000W. That means faster charging, more stored energy, and reliable power whether you're backing up your home, running an off-grid cabin, or building your own solar farm.
Scalable Solar Power, 4 kW to 12 kW
SolarX 4K lets you decide how much solar power fits your life. Use one unit to cover daily essentials, or scale up to three for your whole home. It connects to your existing solar setup via AC coupling, keeping BLUETTI's DC input ports free for extra panels, so you get more energy, faster, without tying up your system.
Apex 300+B300K+SolarX 4K
Charge to full in just 1.9 hours with 4,000 W solar, fast enough to keep lights, small appliances, and everyday devices ready when needed.

Great gift
It’s really hard to find a wallet with a mesh ID window. This one looks great and fits very well in the back pocket.

Herschel is seriously the Best!
Color: Black Tonal
Got this for my teenage son & it was the perfect size for him. He didn’t want a bulky wallet, just something simple to carry his school ID, cash and his debit card. Herschel has amazing quality products, definitely can’t go wrong with them! Worth the price for sure :)

Nice and thin
Color: Black Tonal
Slim wallet. Made for a minimalist type of person. Ideally for only about five cards and some cash anything more the wallet will start to bulge.

Minimal and Magnificent
Color: Black Tonal
I've had more than a few front pocket wallets, and this one is up at the top. It's sturdy even though it's thin, and the stitching is even. Card retention is great with room for 1-2 cards per pocket, as well as room for a few bills to fit comfortably in the middle pocket. Probably going to buy another as a backup.

Perfect size, style, and material
Color: Ivy Green/Chicory Coffee
I love the Charlie wallet, it’s so sleek, fits everything you need, looks good, and made out of the best material. The amount of pockets plus the center fold makes this a really hard product to beat
