Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a temporary emergency generator, safety means the protections the listing actually states, such as heat-dissipation holes; a pick that states none scores zero on that line. The Wtobybt listing states a 2 Year Manufacturer warranty, while the other listings state no usable warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Wtobybt 20W Hand Crank | 9.5 | 24 | 21 | 20 | 5 | 2 |
| Generic Hand Crank Generator | 9.5 | 26 | 20 | 20 | 6 | 0 |
| MENYAOCO 20W Hand Crank | 9.5 | 24 | 21 | 20 | 5 | 0 |
| Mahugde 20W Hand Crank | 9.3 | 23 | 19 | 19 | 0 | 0 |
Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree.
How to choose the best temporary emergency generator
Match watts to the load
The Wtobybt, Mahugde and MENYAOCO listings state a 20W maximum, which suits low-draw devices such as phones and radios. The Generic listing states no watt figure at all, so its place is with the small-device group. Start from the load you must keep running, then check the watts the listing states, and see the solar panel vs generator for cabin guide for the cabin side of the same choice.
Run time and fuel
The hand crank models carry no fuel at all: the MENYAOCO listing states plainly that its unit generates power only while cranking and stores no electricity internally, while the Generic listing states a built-in 1000mAh battery with a USB output. A hand crank model suits power with nothing to fill. See the best inverter generator for long run time guide for more long-run options.
Weight and size for carrying
The 20W hand crank models list 5 by 3.39 by 3.46 inches, with the Wtobybt and MENYAOCO listings stating 1.81 pounds, while the Generic listing states about 331g at 3.9 by 2.3 by 1.3 inches. The Mahugde listing states the same 5 by 3.39 by 3.46 inch size but no weight. If the generator must travel in a bag, pick a hand crank model.
Outlets and voltage options
The Wtobybt listing states outputs of 3V at 6.6A, 5V at 4A and 6V at 3.3A with a direct output voltage up to 28V, and the MENYAOCO listing states regulated settings of 3V, 5V, 6V, 9V, 12V and 15V plus about 28V direct output. The Generic listing states a USB output from its 1000mAh battery, and the Mahugde listing states multiple output ports with about 28V direct output. Set the regulator to 5V before using the USB port on the hand crank models, as the Wtobybt and MENYAOCO listings state.
| Generator | Voltage options | Storage |
|---|---|---|
| Wtobybt 20W Hand Crank | 3V, 5V, 6V outputs, up to 28V direct | Not stated |
| Generic Hand Crank Generator | USB output | 1000mAh battery |
| MENYAOCO 20W Hand Crank | 3V to 15V regulated, about 28V direct | None, cranking only |
| Mahugde 20W Hand Crank | Multiple output ports, about 28V direct | Not stated |
Read the warranty lines closely
The Wtobybt listing states a 2 Year Manufacturer warranty. The Generic listing gives a warranty description of “Generic”, the MENYAOCO listing gives “Standard warranty”, and the Mahugde listing gives “1” with no unit, so none of those state a usable term. Check the warranty description line before you buy.
