Description
Work out how many charges your power bank gives each device
Casumo
Ilquanderoz Charge answers the question every power bank owner eventually asks: how many full charges is this thing actually good for, and how long will each one take? Instead of guessing from the number printed on the casing, you get a clear figure for every device you own, worked out from real capacity, efficiency and the output wattage you have chosen.
Start by building your device library. Pick from the presets or enter your own hardware by hand, giving its capacity in mAh or its draw in watts. Phones, tablets, headphones, handhelds, a torch, a camera — anything you charge can sit in the library and stay there, ready for the next time you need a quick answer.
The main panel is where the power bank itself lives. Set its rated capacity, how much charge is left in it right now, the efficiency you want to assume and the output wattage you will be charging at. Every device card updates as you adjust those values, showing the number of charges available, the usable mAh behind that figure, the equivalent in watt-hours and the time to a full battery on that particular device. Raise the wattage and watch the hours fall; lower the efficiency to a more honest figure and watch the charge count follow.
Casumo
For the days when one device is not the whole story, order your hardware into a charging queue. The bank then drains step by step down the list, with cumulative hours building as you go and a clear marker at the point where it finally runs out. It is the fastest way to find out whether the bank in your bag will see the phone, the earbuds and the tablet through to the evening, or whether something will have to be left out.
Rearrange the queue, swap a device in or out, nudge the remaining charge down to where the indicator actually sits, and the numbers follow immediately. Planning a long journey, a day of filming, a weekend away from a socket or simply a long commute becomes a matter of reading the figures rather than hoping for the best.
Casumo
Ilquanderoz Charge keeps the maths out of sight and the results in plain view: capacity in, charges and hours out, for the exact devices you carry.
