Take your telescope anywhere with Celestron’s largest capacity portable, rechargeable power supply. Whether you have a computerized telescope or operate your telescope using motors, Celestron specially designed this product with the amateur astronomer in mind. First, you’ll find a 12V cigarette lighter port for your astronomy gear. This battery is compatible with all Celestron computerized telescopes for maximum versatility. You’ll also find two USB ports on board to keep your smartphone, tablet, GPS, or speaker charged and ready all night long. When your eyes are dark adapted, grab the removable red LED flashlight to navigate your observing site without sacrificing your night vision. When the session is over, turn on the bright white LED flashlight to illuminate your site and ensure no lens caps or eyepieces are left behind. There’s also an AM/FM radio and siren feature built right in. When you’re not observing, keep this battery charged and at the ready for unexpected emergencies. PowerTank can help you top off a weak car battery with the included positive and negative terminals. This sealed lead acid battery offers safer and more stable chemistry compared to low-quality lithium ion batteries, and features a built-in circuit breaker for even more safety.
