Travel Use
Meeting the challenges of worldwide voltage and European electrical sockets, you can easily charge up your AA and AAA rechargeable batteries using Synergy Digital’s Battery Charger at home and on the go. The compact, 1.5” W x 4.25” H x 2.75” L battery charger is outfitted with a standard, flip-out AC plug for easy charging, featuring universal 110-220 VAC voltage adjustment for worldwide travel use. Additionally, it also comes with a European adapter featuring two round pins to accommodate most continental European outlets.
High-Energy Density
Each Synergy Digital AA Battery provides 1.25 volts of power with 2800 mAh of capacity to provide long-lasting, continual use. Boasting a high-energy density and high-power capability at a more constant rate, the battery is made of Nickel Metal Hydride to provide long-lasting, reliable power. An Ni-MH battery delivers substantially more current than an alkaline battery and the high hydrogen content of Nickel Metal Hydride is double the battery capacity compared to nickel-cadmium batteries. Furthermore, each battery is made with high-quality Japanese cells to ensure long-lasting use so you never have to worry about draining off the battery the moment you really need it.
Suitable for NiMH and NiCd Batteries
Designed to replenish the energy capacity in your batteries quickly and efficiently, the Synergy Digital Battery Charger is suitable for NiMH and NiCd rechargeable AA and AAA batteries. Simply place your rechargeable batteries in the charger, flip open the AC plug and place the charger in your wall outlet. The voltage of the battery will increase during the charging process until the battery is fully charged, and the green light indicator will turn on when charging is complete.
Long-Term Value with Safer Usage
Unlike single-use batteries that have to be thrown out after a short period of time, Synergy Digital’s Ni-MH, 2800 mAh Ultra Hi-Capacity Rechargeable AA Batteries can be recharged up to 1,000 times so there’s less waste. Not only do you get more bang for your buck, but Nickel Metal Hydride is also free of toxic heavy metals to deliver ultra-strong power for your devices over and over again.
Four Pack of Batteries
The Synergy Digital Battery Charger comes complete with four, Ni-MH, 2800 mAh Ultra Hi-Capacity Rechargeable AA Batteries, allowing you to power up any device that accepts rechargeable AA batteries. With this 4-pack of Nickel Metal Hydride rechargeable batteries, you can power your household electronics, including digital cameras, photo equipment, flashlights, gaming devices, toys, clocks and more. For best performance, recharge whenever energy capacity drops 30- 50% below its peak capacity.

The item was brand new in perfect condition, the only thing I was wondering when charging batteries. Why if four batteries are charging why does the device show red indicator on one side and green on the other side , if take out 2 batteries still shows red and green??And batteries would be charging for like four hours , it is a fast charger ? I’m confused about this device ..
