Es una bateria portatil excelente no solo para uso con telescopios motorizados, se puede usar por si sola para ir de campamento, su versatilidad es excelente.

Works well. A little heavy. Radio is pretty silly. But for why I got it, perfect.

Build quality is excellent. Many uses beyond astronomy. Keeps my phone charged all the while lowering my mount for several hours, with plenty of power to spare. I just keep it in my car for emergency road use. Includes charger that plugs into cig lighter in the back. Recommended.

Me hace un servicio muy bueno lo he usado para la monitorizacion del Goto de telescopio durante tres dias seguidos antes de necesitar volver a cargarlo. Un poco pesado pero es normal debido a su duracin entre cargas

Haven’t use it in any heavy duty conditions but so far it performed great. It comes with everything you need.

Works great with my CGEM DX 1100HD. The power will last at least 2 FULL nights before recharge. I don’t know how much longer because it’s never died.
Other details are listed.

An essential accessory for anyone with a telescope and a goto mount, unless you like stocking up on batteries!. All in one with plug-ins to fit most sockets and car cigarette plug-ins. Its a little heavier but very useful.

Does a good job. I use it selectively for my laptop heating pad and to power my mount. I have a deep discharge battery for other functions, but this unit is lighter and good for 2 hour local club star parties.

It may be too early to review this item as it has only been a month. I bought the 17Amp supply to power my Go-to scope and associated heaters, lights, GPS and etc. This unit replaced the Celestron 7amp battery which lasted 6 years. So far, all components/features (including the charger) work as advertised. I’ve used/recharged the supply 3 times with no problems. I would recommend it to anyone powering telescopes. So far, I’ve had a sour history with Celestron’s customer support, but their products are generally of good quality and this power supply is doing what it was designed for.

The title tells it all. I’ve had this for three years and find its meany features to be practical and 100% reliable. You just never know when you’ll need it, whether a power failure from a storm, a weak car battery, or just need a strong portable light or 12V plug-in source. I’ve seen a lot of things that purport to do some or all of what this product does but never one that comes as close to this one at doing it all so well. And I don’t even have a telescope!
