V10 Universal Battery Charger for 18650, 26650, AA, AAA and USB Boost Output

If you own several rechargeable battery sizes and chemistries, a single charger that covers them all keeps things simple. The V10 universal charger accepts 3.7V Li-ion, 3.8V Li-ion, 3.2V Li-Fe and 1.2V NiMH cells, including common sizes such as 26650, 22650, 26500, 18650, 18490, 18350, 17670, 17500, 17355, 16340, 14500 and 10440 alongside NiMH AAA, AA, A, SC and S. It measures 113mm x 38mm x 29mm and runs from a 5V 1A adapter. A SELECT button lets you pick the right battery type and switch between 500mA and 1000mA charging current, while a four-stage LED shows 25%, 50%, 75% and 100% charge. The charger also offers a USB 5V boost output at 1000mA when powered by a 3.7V or 3.8V lithium battery.

Features and Construction

The charger combines multi-chemistry support, selectable current and a simple button and LED interface in a compact body. It is designed for users who want one unit to handle both cylindrical lithium cells and standard NiMH sizes, with intelligent voltage monitoring handling charge termination according to the chosen type.

Material and Build

The source text does not specify housing or contact materials, so this description sticks to what is confirmed: a unit measuring 113mm long, 38mm wide and 29mm high. It operates from a DC input of 5V–1A and charges at either 500mA or 1000mA. Battery charging ends through intelligent voltage monitoring rather than a fixed timer, with full-charge voltages listed as 1.42V–1.55V for NiMH, 4.25V for 3.7V Li-ion, 3.65V for Li-Fe and 4.35V for 3.8V Li-ion.

Size and Practical Fit

At 113mm by 38mm by 29mm, the charger has a small footprint that suits a desk, shelf or workshop bench. The dimensions come from the source text and give a clear idea of the space needed, but no weight or cable length is stated. The USB output is 5 ± 0.2V at 1000mA, and the charger supports a broad range of cell lengths because the listed battery types span 10440 up to 26650. That range means you can charge small camera or torch cells and larger high-capacity cells on the same unit, provided the correct mode is selected.

Uses and Placement

This charger suits households and professionals who regularly use rechargeable batteries in torches, cameras, clocks, remote controls, toys and similar devices. Its USB boost output adds a second use: drawing power from a 3.7V or 3.8V lithium battery to charge or run suitable mobile electronics when no other power source is available.

Event or Professional Use

For photographers, security staff, event crews and tradespeople who depend on charged batteries, the V10 can serve as a single charging point for several cell types. The four-stage LED indicator shows level at 25%, 50%, 75% and 100%, so you can see progress at a glance. The selectable current is useful when time matters: 1000mA charges faster than 500mA, while the lower setting may suit smaller cells, although the source text does not give charge-time figures for any battery size.

Everyday Home Use

At home, the charger keeps AA and AAA NiMH batteries ready for remote controls, wall clocks, wireless mice and children's toys, and handles 18650 and 26650 cells used in torches and power banks. Simply insert the battery in the correct direction, connect a 5V 1A adapter and choose the charging type; if you do not choose, the charger charges in its default mode. The SELECT button can be held during charging to change the current, and pressed to view the battery charging type.

Benefits and Buying Value

The main value is consolidation: one charger covers a long list of lithium and NiMH sizes, so you do not need separate units for each chemistry. The USB boost output adds standby power for mobile devices when running from a suitable lithium cell, though it is inactive while the charger is connected to an adapter.

Reuse and Low Maintenance

By charging 3.7V Li-ion, 3.8V Li-ion, 3.2V Li-Fe and 1.2V NiMH cells, the V10 supports repeated use of rechargeable batteries rather than disposable ones. Intelligent voltage monitoring manages termination for the selected chemistry. The source text does not give a lifespan, cycle count or warranty, so no claim is made about how long the charger or batteries will last. Keep the unit dry and use the specified 5V 1A adapter.

Why Choose This Product

Choose the V10 if you want a compact charger with a wide battery list, selectable 500mA or 1000mA current, a 25%/50%/75%/100% LED indicator and a USB 5V boost output for suitable mobile devices. It is important to select the correct charging mode for each battery, because Li-Fe and 3.8V Li-ion cells need their own setting. The source text notes that the USB output suits most mobile electronic devices on the market, but not all 5V products have been tested, so some may not be compatible.
