All are available at a reasonable price.Ĭase 1: Virtually silent, only heard very minor hiss when ear is pretty much on the unitĬase 2: Only noticeable hiss when you put your ears near the unitĬase 3: Loud whine lasting the only the first few seconds, faint charging noise after that.Ĭase 4: Loud whine, and it goes on for a few seconds and off for a few (voltage drop causing charging circuit to shut down)Ĭombo 1: Sony or Samsung charger + Sony or Samsung USB cable + extension cord = Case 4Ĭombo 2: Sony or Samsung charger + Any cable = Case 3Ĭombo 3: Apple 1A charger + Sony or Samsung USB cable = Case 2Ĭombo 4: Anker charger + Sony or Samsung USB cable = Case 2, slightly quieter than combo 3Ĭombo 5: Sony or Samsung charger + long 6ft Anker cable (same cable length as Combo 1) = Case 3Ĭombo 6: Apple 1A charger + Anker cable/ Chord Mojo's bundled cable = Case 1Ĭombo 7: Anker charger + Anker cable/ Chord Mojo's bundled cable = Case 1, slightly quieter than combo 6 directly compared, with no pattern to the noise (always the same loudness)Īnker PowerPort is tested at it's worse case scenario(unloaded), the ripple and spike measurements are better when the charger is fully loaded with devices. Chosen Anker PowerPort 5 for good measured performance and multi-port charging with Anker PowerLine due to good construction with braid + foil shielding.
Your hand alone will easily soon bring the unit down to a reasonable temperature.įurther testing on the charger and cable compatibility. In fact if it's feeling mildly hot at first to your hand. note the battery is safe to 150 degrees and the trips all operate up too a hundred degrees lower. If it is prevented from doing this perhaps by being insulated I some way it's temperature will rise until one of the three shut down trips operate. This can only work if there is a temperature differential between itself and its ambient surroundings if there is an insufficient gradient between them, the Mojos temperature will rise until there is a large enough difference to pass its heat to the air surrounding it. The Mojo's case can only shed its heat through convection or by radiating it away. However the electronics and battery are thermally bonded to the aluminium case. It's only about 1.7 watts and when it's charging it adds about another watt so its not much really. Picking up on an earlier post Mojo actually does not dissipate a lot of heat when it's working. Mojo actually has three independant thermal cut outs a special high temperature battery and very sophisticated charging circuitry.
