RoboLite

Anyone who packs for off-grid trips knows the pile: a flashlight, a lantern, a power bank, a charger, spare cells. RoboLite's premise is that adventurers need power delivered where it is needed rather than more gear. According to the maker, it consolidates lighting, device charging, DC power and battery charging into a single hub aimed at camping, car camping and power outages.

Five jobs, one system

• Spotlight
• Camp light
• Mobile power bank
• 5–30V variable DC output via DC5521
• AA and AAA battery charging

The light and power module includes a multi-purpose stand that doubles as a handle and adjusts through 360°, so the light can be aimed at a cooking area or swung toward the surroundings without being held, the maker says.

Scale by stacking

Rather than shipping one oversized battery, RoboLite lets users add power modules that join through a magnetic snap-fit interface. The maker states that a single module delivers up to 140W over USB-C and up to 150W over DC5521; connecting two raises DC5521 to up to 300W. Beyond that, per-port limits stay at 140W for USB-C and 300W for DC5521, while total battery capacity and overall system power grow with each added module. The standard power module holds four 21700 cells for 72Wh, and the lighting module accepts two 21700 cells, adding roughly 36Wh.

Variable DC and hybrid charging

The DC5521 port is adjustable from 5V to 30V. Common presets of 5V, 12V, 19V and 24V are available via a quick switch, with a finer mode stepping up to 30V. The campaign gives examples such as running a projector at 19V or a car fridge at 12V or 24V through a compatible adapter cable. Because the voltage is user-set, confirming a device's requirement before connecting is essential.

USB-C accepts solar panel input, and DC5521 supports bidirectional charging and discharging. With a compatible external source, incoming power can feed connected devices first and route any surplus into the internal battery. Stacked modules charge together through the bottom power module, which takes up to 140W input and passes up to 65W to modules above, according to the maker. Thermal management monitors internal temperature and balances power between lighting and discharge when both run at high load.
