Recently, XTAR released their new products - BC4 charger and UL1 USB light. I bought them. Now I’d like to share some opinions about these two items. XTAR BC4 charger Firstly, let’s see the package and appearance. In the package, there are: 1 x BC4 charger 1 x lanyard 1 x USB-C cable It has a translucent cover that is dustproof and drop-proof. A ribbon inside allows you to easily remove the batteries. This charger only has simple LED indicators to show the charging status. But that also makes the charger in a very small size, easy to carry. BC4 charger is completely different from other chargers of XTAR. It charges 1.5V Li-ion and 1.2V Ni-MH batteries. Of cause, the battery size only could be AA and AAA. The charging current is 0.5A. What I like is the charger will automatically cut-off when fully charged the batteries. The XTAR 1.5V AA lithium-ion battery has a capacity of 3300mWh and a discharge current of 2000mA. They can replace the 1.5V disposable batteries. I didn’t have any AA flashlight, so I use them to replace my Ikea batteries for the camera flash. There are two additional functions - USB output and LED light. When you need emergency charging for your phones or iPads, just install four batteries into the BC4 charger, and use the charger as a power bank. You’d better use AA batteries I think, because the capacity of AAA batteries is too small. The LED lighting is much bright than the phone flash. XTAR UL1 UL1 is a mini USB light. It is only 15g. There is no built-in battery, so you need to plug it on the power bank or wall plug. There is a metal hose that can be bent arbitrarily, which can realize multi-angle light source control. The switch key has single-click and double-click functions, the operation is simple: Long press for more than 2S to turn off Single-click to light up in turn the white light (60 lumens) / white light (120 lumens) / red light (35 lumens) / blue light (35 lumens) / green light (120 lumens) / red and blue flashing (351 lumens) Double-click to switch to white light strobe mode (120 lumens). It can be used as a night light. The white light flashing is used for self-defense, red and blue flashing for providing assistance signals. All light colors: White light flashing: Red and blue light flashing: I just did a simple test. There are more specifications of BC4 charger and UL1 USB light at the XTAR official website.
