We had an outwell jupiter. Heap of junk. Both bulbs packed in just over the 1 year warranty period, the mains charger never worked, the car adaptor was tempremental and the battery lasted less than 1 evening.
We now have a pair of Ring lanterns, cost about £32 in most camping shops but you can get them for £19.49 from 7dayshop. Car-chargeable and wind-up if a boost is required. The light is a bit stark compared to a gas-mantle lantern but very useable. Also very light and compact.
