How does charging the Mophie Juice Pack work?
The short answer is that you only have to charge the case. You can either do this with the iPhone in the case to charge both at the same time, or you can remove the iPhone and charge it separately.If the iPhone is inserted in the case when charging, the iPhone will be charged first, and once fully charged, the battery will then be topped up. If you are charging only the case without the iPhone inserted, then obviously only the battery itself is charged. Charging both together is generally the most convenient approach, and will probably work on a normal, daily basis just by leaving your iPhone in the case and plugged in overnight. However, if you're in a hurry, removing the iPhone and charging it separately will allow you to get both the iPhone and the case topped up more quickly. Remember that if the iPhone is in the case, then it gets charged first and then the battery in the case gets topped up after the iPhone is fully charged. By charging both separately, you can recharge the battery in the case while charging your iPhone simultaneously.
Does proximity to magnets damage or affect batteries?
I assume you are talking about portable cylindrical batteries like AA, 18650.Magnets do not seem to affect these batteries in any significant manner except in the event of a freak accident.The distance between the positive and negative is just a very small gap. In a freak accident a magnet could snap on the top end of a magnet and connect the positive and negative, that would cause a short circuit, the battery would heat up and could cause a fire.Usually there is some form of protection at the top end of the magnet to prevent this, but not all batteries have it, and for old batteries the protection might have been removed.In this kind of accident, any coin, paper clip or small conductive object will have the same effect as a magnet, but a magnet is more hazardous, because it snaps on and stay on, for a non-magnetic conductive object, any accidental connection could be for a very short time and the connection is on and off.
When I charge my power bank, the first light is blinking but not charging. Is it broken already?
This shows that the power bank got discharged too far, it has some bad batteries in it, or less likely, there is another fault. It is not very likely, but the charging cable may be too thin or too long. So try a different USB cable. Likewise, the charger might have an issue and be too wimpy. Try a different charger.The power bank circuitry is conceptually simple. The power bank engineers choose a maximum charge voltage, and a minimum voltage. When plugged into a charger, the power bank charges its batteries until it reaches the maximum charge voltage. When powering a load, the power bank provides power until it reaches the minimum voltage. At the minimum battery voltage, it shuts off to protect the batteries from being discharged too far. The lower you discharge a lithium ion battery, the shorter the battery life (in terms of charge/discharge cycles). Likewise, a higher maximum charge voltage also shortens the battery's life. There is no free lunch. The battery will support many more cycles if it isn't charged very high, nor discharged very low, but the battery pack will have a much lower capacity. The LEDs are a very non-linear voltage display. The battery datasheet includes charts showing the battery voltage as it discharges into a constant load. The power bank designers look at the discharge chart. The voltage where the power bank shuts off is 0%. The voltage where the power bank charger stops charging is 100%. The 3 intermediate voltages are just read off that chart. Your power bank will only blink one light, until the battery pack charges up to the voltage that corresponds to a 25% charge. If the battery was ever discharged too much, or the battery is defective, the charger in the power bank may never be able to get it up to a 25% charge.
How much time does it takes to charge the power bank 6000mAh for full charge?
Hi, thanks for A2A.The charging time basically depends on the charger you use. A formula to solve how long to charge a power bank:Charging time in hours = ( power bank capacity in mAh) /(charging rate in mA)Literally there are 2 factors will affect the charging rate : Output of charger & Input of power bankCurrently most power banks are designed with 5V 2A input standard, which stands for the biggest amount of flow it can accept.Theoretically USB port of the lpatop will deliver 0.5 A per hour.Applying the formula above the power bank 6000 mAh rated charging time = 6000 mAh / 500 mA = 12 hours.If you use charger of 1A, then it will take 6 hours for 6000 mAh power bank.If you use high rated current chargers, charging time will reduce.Hope it helps!
