PowerextraOsmo Action 4&3 Battery Set, 2 Pack 1850mAh Rechargeable Batteries with Fast Dual USB-C Charger Compatible with DJI Osmo Action 4/3 Camera Accessories

Work well good battery life

Look to be very good value.

I am taking my Osmo action camera everywhere and these batteries that come with the charging port are a very good addition to my gear.Besides the fact that the set has two 1850 mAh batteries, they are also rechargeable which allow me to have my camera ready for action at any time.I like the fact that the batteries hold a charge for quite a long amount of time which allows me to shoot videos and take photos without worrying that they will run out of power too quickly.The dual USB charger is fast and efficient and it can charge both batteries simultaneously which saves a lot of time especially when I have to prepare for a day of shooting.The actual set is very compact and lightweight which is very convenient considering that I have a lot of gear to carry with me one filament.These batteries are definitely very efficient for me and they are reliable solutions for my workflow and since I'm using them I did not have any issues and therefore I am very happy with how they are performing.

I requested these for use in my action 4 camera and I must say I am impressed.These are rated at 1850mAh where as my existing original battery is 1770 mAh, so that is a boost for a start, plus it means I now have more batteries to extend my shooting time and never have to worry about running out of power again.They obviously fit in the camera without a problem and I think for the price they are great. You do get a charging case, that is in the case does not charge the batteries but you can charge both batteries at once in the case using a USB C cable, the bonus is they accept a fast charge.In conclusion, for the current price at the time of review which is £39.59, there is also a 10% voucher which makes them even cheaper, that is a great price. These have got to be 5 stars all the way.

The two Li-ion rechargeable batteries provide long battery life, which is perfect for my long shooting sessions. The dual charging dock is incredibly convenient and supports fast charging, allowing me to charge both batteries simultaneously. I love that it can be charged anywhere—whether at home, in the car, or on location—with various charging options, including adapter, car, laptop, and power bank charging.The intelligent LED indicators on the charger are super helpful, clearly showing when each battery is charging (red light) and when they’re fully charged (green light). It takes the guesswork out of knowing the battery status, which is a great time saver.I also appreciate the multiple safety protections built into these batteries. The overvoltage, overcurrent, and overcharge protections give me peace of mind, knowing my camera is safe during use and charging.Overall, this battery kit is a must-have for any Osmo action camera user. It’s reliable, versatile, and offers great battery life. Highly recommended!

These Powerextra batteries work nearly as well as the oem ones. I've been getting well over an hour out of them on average when shooting for long periods on lower quality settings which seems inline with the product description.So far they've performed faultlessly and I've had no issues with them. Great to have some extra battery power available as a back up.

You really can't fault these for the money, and they're pretty much an essential accessory/addon for your Osmo.I've had many 'compatible' sets before, and while most have been OK, some have shown their true colours as being 'budget' alternatives soon after a few recharge cycles.This set falls into the first category... well made, reliable, and no worrying signs after several discharge/recharges.Good stuff, and on a quality/value-for-money basis.... 5-Stars.
