How we assign awards →The differences that matter
- Continuous output, 700 W vs 200 W → a resistive appliance such as a kettle or a hair dryer is outside the second one's limits.
- Capacity, 448 Wh vs 128 Wh → at a 100 W load the first lasts about 4.5 hours, the second a little over one.
- Weight, 6.7 kg vs 1.7 kg → the second fits in a bag; the first is carried by hand.
- Warranty, 5 years vs 3 → the first stays covered two years longer.
