You get in the car on a cold morning, turn the key, and nothing happens, just a weak click or a slow crank that never catches.
It’s cold out, though. Do you really want to go digging for a portable jump starter and then stand in front of your car setting it up, hoping it actually charged since the last time you used it? The ANCEL BS200 means you don’t have to, because it’s already under the hood, monitoring conditions and ready to spring into action when your engine fails to crank.

Supercharge Your Jump Start
Most portable jump starters run on lithium batteries, so they only help if you remember to charge them ahead of time. The BS200, on the other hand, uses a supercapacitor. It’s also installed under the hood, so it’s always ready to go, meaning you don’t have to fish it out of the center console or your trunk.
A supercapacitor doesn’t need the same babying a lithium pack does. It’s rated for more than 500,000 charge and discharge cycles, operates across a wide temperature range from -40°F to 176°F, and draws 3mA or less on standby, so you won’t even notice it’s connected. Because it replenishes itself from the vehicle during normal driving, with USB-C available as a backup charging option, you don’t even have to get into the habit of charging it.
And it’ll deliver 700A of peak starting current, so even batteries on the brink of death get a real kick to get you on the road.
Always Ready & Permanently Installed
Unlike a portable jump starter that you need to remember to store, charge, and retrieve whenever you need it, the BS200 goes under your hood and stays connected to the vehicle after you install it. That means it’s already there when the battery struggles to start the engine, so you’ll never have to dig your jump starter out of the trunk or wonder if you charged it the last time you used it. The BS200 can also recharge itself as you drive, so it’s already set to help provide starting support the next time you need to use it!
Built for Winter Mornings Specifically
Cold weather is where batteries fail first, since AAA data shows a battery loses about 35% of its strength at 32°F and closer to 60% at 0°F. That means a battery that’s already struggling gets hit hardest exactly when it can least afford it, and it’s what the BS200 was built for.
You get in your car on a cold morning, the battery’s weaker than usual, and the engine barely turns over, but since it’s already connected and monitoring, it can offer starting support right then and there.

Kick Dying Batteries Back to Life, But Not Forever
The BS200 isn’t a replacement for a failing battery, so don’t treat it as one.
If your battery is starting to slow down, though, it’s perfect. You can pair an app with the device to track your battery and its starting behavior over time. This means you can actually watch changes building instead of just waiting for the morning your battery seemingly fails out of nowhere. If you’ve got an aging battery, or you’ve got vehicles that sit for long stretches between drives, it’s perfect.
Plus, when voltage has dropped further than a normal jump can handle, BS200’s Force Start feature offers another recovery option, though it can’t guarantee that every dead battery can be revived.
A Full Lineup For Different Starting-Current Needs
The BS200 is built to fit 12V gas and diesel vehicles, with a reference range up to 3.0L naturally aspirated or 2.5L turbocharged. A vehicle can still be compatible with the BS200 even if the engines are larger, it’s just a matter of the car’s actual starting-current requirement falling within 700A. Compatibility largely depends on the vehicle’s actual starting-current requirement, rather than simply its engine displacement or vehicle weight classification.
If you’ve got a full-size truck, a larger SUV, or a vehicle with a bigger starting load, ANCEL’s larger BS300 or BS400 units are what you’ll need instead.
But, if what you’re driving is a small- or mid-size car on daily commutes, in cold-climates, or you’ve got an aging-battery, the BS200 works, and it’ll be there when you turn the key and hear nothing but a series of sad clicks.
