Most units looks like chunk, if you compare them to the ecoflow product in the same price tag.
- Charging times at wallplug
- mppt solar charging capabilities
- strength of 110v / 220v Inverter (with X-Boost)
- USB-C 100 Watt Charging, the competiors mostly are limited to PD 60W
- battery technology (
LiFePO4)
- Internal Wall-Charger (you just need a cable)
the jackery 1500 is junk. Is just used by instagram/youtube travellers who got payed well for showing it (like Eva Beck).
Compare the tech specs against a ecoflow delte 2, any value is worse at the jackery. And the pricetag is high of the jackery.
I did wrote about the delta 2 and possible upgrades
recently. Too about, how you can use a booster for car charging.
