Used Mobile 2 a handful of times. Put it away for a week or so. Took back out and the battery was dead. I charged on multiple different devices and only get a blinking green light and first light. Going on an assignment tomorrow and need help! Thanks!

When the battery gets very low on the osmo you need to charge it with a charger that is capable of at least 2amps of current.

Hi, sorry to know this, are you using a cable that has a capability of 5V and 2A? How long did you charge it? Did the Osmo mobile 2 respond after you unplug it?

This should be an FAQ (hey, DJI!), it gets asked so frequently.

As DJI says in the user manual (page 5):

"Charging Time: 2 hours (when charging at 2 A)".

USB ports on a computer can only deliver a limited amount of current. USB 1 and 2 ports can only deliver 300 to 500mA. USB 3 ports max out at 900mA. This means that charging on a USB port on a computer (Mac or Windows) will not be able to charge your device in two hours. Charging on a 300 mA USB 1 port will likely take about 14 hours, without interruption.

The only way to charge your device in two hours is to use an external charger capable of delivering 2 A (or 2,000mA).

The input voltage of the charger (110, 240, whatever) does not affect the charge time. The output voltage of a USB charger is always 5 Volts. Only the output current (the Amperage) of the charger matters.

Find a USB charger that puts out 2 Amps. Your device should charge in about two hours. Here's how:

Grab any charger you have with a USB port on it. Look at the label.  There, you'll see that it's rated at 5 Volts. This is the output voltage of all USB ports, and all USB chargers.

Now, look on the label for either A, Amps or mA (milliamps). This is the amount of current the charger can deliver. This is the determining factor for how fast your stuff (OSMO, phone, whatever), charges.

While your computer does have 5 Volt USB ports, the USB standard says that these ports can only deliver between 300mA (1/3 of an Amp) and 900  mA (almost 1 Amp, 1000mA). That's not a defect; it's literally a standard.

A standard iPhone USB charger can provide 1 Amp, so charging your OSMO  will still take more than four hours. Some iPad chargers provide more  than 1 Amp, so charging will be faster.

DJI's OSMO 2 manual says that your OSMO will charge in two hours, provided that the power source is capable of providing a full 2  Amps. Using math, we can assume then, that if your charger only provides 1 Amp, it will take at least twice as long to charge, so about four hours.

You can also charge your OSMO from an external battery or charge cell.  Some of these are capable of providing the full 2A required to get your  OSMO 2 charged in the advertised two hours.

Your OSMO is charging on whatever you've got it connected to (as indicated by the blinking, white LED), but that USB port on your computer isn't going to charge it in two hours.

Your options: wait for the OSMO to charge very slowly on whatever you have it connected to. Or find a USB charger capable of providing more amperage, ideally 2 Amps.

Hope that helps.

I don’t understand why there are not thousands of angry people wanting blood from DJI, they design the circuit to LOCK all their battery products once they go beneath a certain voltage, or what they call deep hibernation, it’s totally unacceptable . My Osmo pocket did it , my brother‘s Osmo pocket did it... and all DJI drone batteries are designed to lock after a certain voltage...They say its  for safety, but let’s face it , its a very convenient reason to MAKE you  buy a new one. I have had experts tell me the highest  majority of ( ANY DJI batteries cells ) are still perfect even though they’ve been  below a certain voltage and  locked , and how convenient, once out of warranty you have to buy new battery or a entire new device from them . I left my Sony and Olympus cameras battery go low over a year and they all charged up, Maybe not perfect and I understand about good battery management, but at least they weren’t forcefully locked
