These times are estimates based on average usage for individual devices and appliances connected to one Dory Sentry.
If your energy requirements are higher, please consider purchasing additional Sentries.
Use one Sentry to directly back up critical devices and appliances. Link 2-3 Sentries to double or triple your backup time. You can connect one or more Sentries directly to your electrical panel for worry-free, whole-house backup.
Keep your electricity bill at bay when you’re at home or on the move. Easily recharge your Sentry via solar panels that connect directly to a built-in MPPT solar charger.
Power important devices and personal luxuries while off the grid. Meet every remote work deadline—so you can take your outdoor adventures to the next level.

Perfect battery for home backup
It works perfectly. After powering my refrigerator for 24 hours, the battery still has 48% of the remaining electricity. This product runs very quietly, with no noise at all in use. This is a compact and sturdy product, easy to carry around and use.
