How long does it take to charge?

CHARGING YOUR DEVICE

How long your power packs will last depend fully on what power pack you are using as well as the power usage of your device. For example, a tablet will take much longer and will take more power to charge than a smartphone.

CHARGING YOUR BATTERY PACK

Most electronics will be able to be recharged via solar power, however we recommend using an EnerPlex power pack as a buffer, since many electronics will stop charging if there is an interruption of power like if a cloud passes over.

How It Works?

Charging times from your solar chargers to Jumpr battery packs and electronic devices will be dependent on the amount of visible sun as well as what specific product you are charging.

EnerPlex solar products charge best in bright and clear sunny conditions, however these solar chargers are also able to operate and collect a charge in cloudy conditions. In cloudy conditions, you will notice the solar charging rate will be slower than in standard sunny conditions. To maximize charging capabilities, we recommend angling your solar panels towards the sun to receive the most direct sunlight.

Why to Charge a Battery Pack Instead of a Product Directly When Charging Via Solar

Overexposure to heat. Some products will shut down if they get too hot and it’s never safe to leave your electronics exposed in sunlight and heat for long periods of time
Cloud cover. If clouds pass by or weather changes, the charging can become interrupted. This means your phone could be plugged into your Kickr or Commandr and not charging. Portable batteries such as Generatrs and Jumprs give you a constant charge no matter the weather conditions and will always accept a charge via solar no matter how many clouds pass over
Transportation. It’s much easier to charge your phone via a portable power pack than sitting in the sun waiting for your device to fully charge. Portable power packs let you charge anywhere
Day vs Night. You can charge at any time while using a power pack while you can only charge via solar during the day when you have access to direct sunlight

How long will it take to charge my Jumpr?

This all depends on the size of the battery you’re trying to charge and the power source you’re using to charge it. The below table can give an idea of the approximate charge times for many of our batteries, when going from 0 – 100%:

EnerPlex Battery	Battery Size	Power source amps: 1000mA	Power source amps: 2000mA
Jumpr Bar	2,600mAh	3 hours	2 hours
Jumpr Flashlight	2,800mAh	3 hours	2 hours
Jumpr Max	10,000mAh	11 hours	5.5 hours
Jumpr Mini/Mini-Li	1,700mAh	2 hours	1 hour
Jumpr Prime 4400	4,400mAh	5 hours	3 hours
Jumpr Prime 7800	7,800mAh	8.5 hours	4 hours
Jumpr Prime 10400	10,400mAh	12.5 hours	6 hours
Jumpr Slate 10K	10,000mAh	11 hours	5.5 hours
Jumpr Slate 5K/5K-L	5,000mAh	5.5 hours	3 hours
Jumpr Stack 3	3,200mAh	3.5 hours	2 hours
Jumpr Stack 6	6,200mAh	7 hours	3.5 hours
Jumpr Stack 9	9,400mAh	10.5 hours	5 hours

Note: USB ports found on computers can vary greatly in their output amperage and may be anywhere from 50mA – 2000mA. Wall chargers that come with your Micro USB-powered phone may have an output of anywhere from 1000mA – 2000mA. This information can be found directly on the charger.
