    "it works fine...The charge lasts a long time....I've been using this Celestron power tank 17 for over three months now and it's been working without issues....Would have given 5 stars, except for the "fidly" detachable light storage, the fact it did not come with a manual (had to download from Celestron), and you still have to order a separate power cord for the telescope."
