The short answer
Buy Anker SOLIX if the battery stays in the house, you want the fastest refill, you need more inverter, or you need 240V.
Buy Jackery if the battery travels, if it will be charged where people are sleeping, or if you value a long cycle rating and a light case over raw output.
Neither brand is better. They have made different trades with the same cells, and both publish the numbers, which is more than can be said for much of this market.
Tier by tier, on published numbers
| Tier | Anker SOLIX | Jackery | Who wins, and why |
|---|
| Small (under 500Wh) | Power banks rather than stations | Explorer 300 — 292Wh, 300W, 8.3 lb | Jackery, on having a real product here |
|---|
| 1kWh | C1000 — 1,056Wh, 1,800W, full in 58 min | Explorer 1000 v2 — 1,070Wh, 1,500W, 24 lb | Anker on output and speed; Jackery on weight |
|---|
| 2kWh | Not covered on this site | Explorer 2000 v2 — 2,042Wh, 2,200W, 20ms UPS | Jackery, on the UPS switchover and quiet charging |
|---|
| 3kWh+ at 120V | F3000 — 3,072Wh, 120V only as one unit | HomePower 3000 — 3,072Wh, 3,000W, 6,000W surge | A tie; choose on recharge and outlets |
|---|
| 240V split-phase | F3800 — 3,840Wh, 6,000W, 120/240V | No portable equivalent | Anker, decisively |
|---|
Figures are each manufacturer's published specifications. Tiers with no entry mean this site does not carry a unit from that brand at that size, not that the brand has nothing.
What each brand optimizes
Anker optimizes for time. Across the range the recharge figures are the aggressive ones — 58 minutes to full at 1kWh, 20ms switchover on the big units, high solar ceilings. Anker also puts the larger inverter in the same size case, and it is the brand that took split-phase 240V into a portable box first among these two.
Jackery optimizes for living with it. Lightest unit in the class at 1kWh and at 2kWh, a published sub-30dB charging mode, and a panel ecosystem designed to plug in without adapters. Jackery also publishes the longer cycle rating at 1kWh: 4,000 cycles to 70% against Anker's 3,000.
Those are different customers, and the honest recommendation follows the customer rather than the brand.
Where the difference actually bites
1. The microwave line
At 1kWh, Anker gives 1,800W continuous and Jackery gives 1,500W. A standard 1,000W microwave draws about 1,500W at the wall, so that 300W is the difference between a working kitchen and a disappointed one. The microwave page explains why the door rating misleads.
2. The flicker test
If your grid drops and returns repeatedly, recharge speed is worth more than anything else on the sheet. Anker's 58-minute full charge refills in a single short window; 1.7 hours does not.
3. The stairs test
Twenty-four pounds goes up stairs, into a truck bed and out to a campsite without a second thought. Thirty-five does not. If the battery moves weekly, Jackery wins on the only specification you will feel every time.
4. The 240V wall
If a well pump, an electric range or a hardwired 240V circuit is on your list, the comparison ends. Jackery's portables are 120V machines. Anker's F3800 produces 120/240V split-phase from one box, and that is a capability no quantity of 120V units adds up to — the well pump page shows why.
What both brands do the same
- LiFePO4 across the current range. Both have moved off NMC in their mainstream stations, which is the change that made this class last — the chemistry page explains the difference.
- App monitoring. Wi-Fi or Bluetooth state-of-charge and output on both, which matters more than it sounds when the unit lives in a basement.
- Published specifications you can check. Both put real numbers on their product pages. Plenty of brands in this category do not.
The short version
- Same energy, same money, different priorities. Choose the priority, not the badge.
- Anker: faster refill, bigger inverter, and the only 240V portable between the two.
- Jackery: lighter, quieter, longer published cycle life at 1kWh, better small-tier product.
- If it never moves, buy Anker. If it moves weekly, buy Jackery. That single question settles most of these purchases.
