“Great light, charger does not work”

“I really like this lantern. The light output is good. You are supposed to run the battery down before charging it the first time. It put out light for a day and a half. The crank is easy. It is not too heavy. I connected my Samsung Instinct charger to it but it refuses to charge even though it is under the 4V limit of the lantern. I really bought this lantern as an emergency phone charger so that is a huge disappointment. I sent an email to egear but never heard back. I would give the lantern four stars but because of the charger issue it is getting three.”
