I purchased an Energen DroneMax A40 in September 2019. The Energen DroneMax A40 worked for about 10 months. Then, the Energen DroneMax A40 would not take a charge. I returned the device and was sent a replacement Energen DroneMax A40. That replacement Energen DroneMax A40 had the same problem, it would not take a charge. I have been trying since mid-August 2020 to try to get a repair or replacement. I have had nothing but the run-around from the Energen facility in California. I am writing this review to warn consumers that the Energen DroneMax A40 is not a dependable device and the Energen support operation is not helpful at all. If you want longer flight times, buy more batteries. The Energen DroneMax A40, and quite possible the entire product line of Energen charging devices, is not dependable and the support system is poor to non-existent. Please share this information with people in the drone community so that they can avoid spending a lot of money for the Energen DroneMax A40, a device that is not dependable with a support system that is not helpful. ### ⭐⭐⭐⭐⭐ Great Investment - Gives Me Over and Hour of Extra Flying Time *by J***Y on November 2, 2017* Great product - extremely well made, rugged, and powerful. I currently have six Phantom 4 Pro batteries and the A40 now makes it like I have ten. I get about 1 hour and 15 minutes of extra flying time by re-charging 4 batteries in the field. This has been a great investment! And...to top it all off, their customer service has been excellent! ### ⭐⭐⭐ Died after 3 months...customer service came through! *by R***R on October 17, 2018* After 3 months and occasional use I now have a very expensive paperweight. When it worked it was awesome. Unfortunately the DroneMax A40 that I purchased will no longer take a charge. Trying to get a response from the manufacturer but so far no luck.Update (Nov. 2018): Updated my initial review from 1 stars to 3 stars as Energen's customer service came through and I now have working A40. No indication was provided as to what was wrong with the original unit...just happy that I have a functioning charger again. ## Frequently Bought Together - Energen DroneMax A40 414WH Portable Drone Charging Station for DJI Mavic Pro/Phantom 3 / Phantom 4 / Yuneec Typhoon 4K / Typhoon H Drone Battery (Charge 4 Batteries & 2 USB Ports Simultaneously) - LORDONE Phantom 3 Battery, 15.2V 4480mAh Intelligent Flight Battery for DJI Phantom 3 Standard, DJI Phantom 3 Pro, DJI Phantom 3 Advanced, DJI Phantom 3 4K, DJI Phantom 3 SE Drone - 4 Pairs 9450 Self Tightening Drone Propeller(4CW+4CCW) for DJI Phantom 3 Professional, Advanced, Phantom 2 Series¡­ --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/55608085-dronemax-a40](https://www.desertcart.co.uk/products/55608085-dronemax-a40) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
